    Protect Your Hearing!
    We value you as a long-term customer. For
    that reason, we urge you to practice restraint in
    the operation of this product so as not to damage
    your hearing and that of others in your vehicle.
    Studies have shown that continuous exposure to
    high sound pressure levels can lead to permanent
    (irreparable) hearing loss. This and all other
    high-power amplifiers are capable of producing
    such high sound pressure levels when connected
    to a speaker system. Please limit your continuous
    exposure to high volume levels.
    While driving, operate your audio system in
    a manner that still allows you to hear necessary
    noises to operate your vehicle safely (horns,
    sirens, etc.).
    Serial Number
    In the event that your amplifier requires
    service or is ever stolen, you will need to
    have a record of the product’s serial number.
    Please take the time to enter that number in
    the space provided below. The serial number
    can be found on the bottom panel of the
    amplifier and on the amplifier packaging.

    Installation Applications
    This amplifier is designed for operation in
    vehicles with 12V, negative-ground electrical
    systems. Use of this product in vehicles with
    positive ground and/or voltages other than 12V
    may result in damage to the product and will void
    the warranty.
    This product is not certified or approved for
    use in aircraft.
    Do not attempt to “bridge” the outputs of this
    amplifier with the outputs of a second amplifier,
    including an identical one.
    Planning Your Installation
    It is important that you take the time to read
    this manual and that you plan out your
    installation carefully. The following are some
    considerations that you must take into account

    Cooling Efficiency Considerations:
    Your JL Audio amplifier employs an
    advanced type of heat management, called
    RealSink™. This feature takes advantage of
    convection and radiation effects to remove
    heat from the amplifier circuitry. For optimum
    cooling performance, the vertical heat sinks
    located at the sides of the amplifier should be
    exposed to as large a volume of air as possible.
    Enclosing the amplifier in a small, poorly
    ventilated chamber can lead to excessive heat
    build-up and degraded performance. If an
    installation calls for an enclosure around the
    amplifier, we recommend that this enclosure
    be ventilated with the aid of a fan. In normal
    applications, fan-cooling is not necessary.
    If mounting the amplifier under a seat,
    make sure there is at least 1 inch (2.5 cm) of
    space above the amplifier’s outer shell to permit
    proper cooling.

    Safety Considerations:
    Your amplifier needs to be installed in a dry,
    well-ventilated environment and in a manner
    which does not interfere with your vehicle’s safety
    equipment (air bags, seat belt systems, ABS brake
    systems, etc.). You should also take the time to
    securely mount the amplifier using appropriate
    hardware so that it does not come loose in the
    event of a collision or a sudden jolt to the vehicle.
    Stupid Mistakes to Avoid:
    • Check before drilling any holes in your vehicle
    to make sure that you will not be drilling
    through a gas tank, brake line, wiring harness or
    other vital vehicle system.
    • Do not run system wiring outside or underneath
    the vehicle. This is an extremely dangerous
    practice which can result in severe damage to
    your vehicle and person.
    • Protect all system wires from sharp metal
    edges and wear by carefully routing them,
    tying them down and using grommets and
    loom where appropriate.
    • Do not mount the amplifier in the engine
    compartment, under the vehicle, on the roof
    or in any other area that will expose the
    amplifier circuitry to the elements.

    Product Description
    The JL Audio HD1200/1 is a very powerful
    and compact monoblock (single channel),
    wide-range amplifier utilizing patented Single
    Cycle Control™ Class D technology. This
    groundbreaking technology delivers referencegrade sonic performance while requiring
    far less current from the vehicle’s electrical
    system than a conventional amplifier.
    Unlike most monoblock amplifiers, the
    HD1200/1 is a wide-range design, so it can
    be used as a subwoofer amplifier or as a very
    powerful mid-bass or mid-range amplifier,
    using a second 1200/1 to form a stereo pair.
    Its effective frequency response is from 6 Hz
    (very low bass) to 8 kHz (lower treble range).
    JL Audio’s exclusive R.I.P.S. power supply
    design optimizes the output the amplifier for any
    impedance between 1.5 and 4 ohms, allowing
    you to get full use of the HD1200/1’s performance
    capabilities with a wide range of speaker systems.
    The tightly regulated power supply design also
    means that the HD1200/1’s clean power output
    capability remains stable over a wide range of
    vehicle voltages, resulting in enhanced fidelity.
    A flexible input and crossover section permits
    operation with a wide variety of source units
    and system configurations. The HD1200/1’s
    preamp output can send pass-through signals
    from the inputs to feed additional amplifier(s).

    Typical Installation Sequence
    The following represents the sequence for
    a typical amplifier installation, using an
    aftermarket source unit or OEM Interface
    processor (like the CleanSweep® CL441dsp).
    Additional steps and different procedures may
    be required in some applications. If you have
    any questions, please contact your authorized
    JL Audio dealer for assistance.
      1) D
     isconnect the negative battery post
    connection and secure the disconnected cable
    to prevent accidental re-connection during
    installation. This step is not optional!
      2) R
     un power wire from the battery location to
    the amplifier mounting location, taking care
    to route it in such a way that it will not be
    damaged and will not interfere with vehicle
    operation. 2 AWG or larger is recommended
    for wire runs greater than 72 inches (180
    cm) in length. This 2 AWG wire needs
    to be reduced to 4 AWG within 36 wire
    inches of the amplifier using a distribution
    block. Use a 1/0 AWG or 1/0 AWG main
    power wire with a fused power distribution
    block when additional amplifiers are being
    installed with the HD1200/1 and are being
    powered from the same main power wire.
      3) C
     onnect power wire to the positive battery
    post. Fuse the wire with an appropriate fuse
    block (and connectors) within 18 inches (45
    cm) wire length of the positive battery post.
    This fuse is essential to protect the vehicle.
    Do not install the fuse until the power wire
    has been connected to the amplifier.
      4) R
     un signal cables (RCA cables) and remote
    turn-on wire from the source unit or interface
    processor to the amplifier mounting location.
      5) R
     un speaker wire from the speaker systems to
    the amplifier mounting location.
      6) Find a good, solid, bare metal grounding
    point close to the amplifier and connect the
    negative power wire to it using appropriate
    hardware. Use minimum 4 AWG power wire,
    no longer than 36 inches (90 cm). In some
    vehicles, it may be necessary to upgrade the
    battery’s ground wire as well. (See pages 6, 7
    for important notice).

      7) S ecurely mount the amplifier using
    appropriate hardware. (See page 8 for detailed
    mounting instructions).
    8) C
     onnect the remote turn-on wire and the
    positive and negative power wires to the
    amplifier’s power connector plug. Then insert
    the power connector plug into the amplifier’s
    power connector receptacle, pushing firmly.
      9) C
     onnect the RCA input cables
    to the amplifier.
    10) C
     onnect the speaker wires to the speaker
    connector plug and insert the plug firmly into
    the speaker connector receptacle.
    11) C
     arefully review the amplifier’s control
    settings to make sure that they are set
    according to the needs of the system.
    12) I nstall power wire fuse (100A for a
    single HD1200/1) and reconnect the negative
    battery post terminal.
    13) T
     urn on the source unit at a low level
    to double-check that the amplifier is
    configured correctly. Resist the temptation
    to crank it up until you have verified the
    control settings.
    14) M
     ake necessary adjustments to the input
    sensitivity controls to obtain the right
    overall output and the desired balance
    in the system. See Appendix C (pages 18, 19)
    for the recommended input sensitivity
    setting method.
    15) E
     njoy the fruits of your labor with your
    favorite music.

    Power and Turn-on Connections
    Before installing the amplifier, disconnect the
    negative (ground) wire from the vehicle’s battery.
    This will prevent accidental damage to the system,
    the vehicle and your body during installation.

    +12 VDC Ground

    Remote

    Please note that lower AWG numbers mean
    bigger wire and vice-versa (1/0 AWG is the largest,
    2 AWG is smaller, then 4 AWG, then 8 AWG, etc.).

    L
    Inputs
    R

    +12V Battery Connection
    You will need to connect a power wire to
    the vehicle’s positive battery terminal, using
    an appropriate power ring or specialized
    battery terminal connector, such as the JL
    Audio XB-BTU or XD-BTS. This connection
    must be tight and corrosion-free to ensure
    proper connectivity. This wire MUST be fused
    appropriately for safety. Any power wires run
    through metal barriers (such as firewalls), must
    be protected with a high quality insulating
    grommet to prevent damage to the insulation
    of the wire. Failure to do so may result in a
    dangerous short circuit.
    Power Wire Requirements
    The HD1200/1’s “+12 VDC” and “Ground”
    connections are designed to accept 4 AWG power
    wire. 2 AWG or 1/0 AWG pure copper wire is
    recommended for any power wire run longer
    than 72 inches (180 cm). This larger wire should
    be reduced to 4 AWG using a distribution block
    within 36 wire inches (90 cm) of the amplifier’s
    “+12 VDC” connector. For runs shorter than
    72 inches, 4 AWG pure copper power wire is
    acceptable.
    If you are installing the HD1200/1 with other
    amplifiers and wish to use a single main power
    wire, use 1/0 AWG pure copper wire as a main
    power wire. This 1/0 AWG power wire should
    terminate into a fused distribution block mounted
    as close to the amplifiers as possible and should
    connect to the HD1200/1 with 4 AWG pure
    copper power wire.

    6 | JL Audio - HD1200/1 Owner’s Manual

    We do not recommend the use of “copperclad aluminum wire” or
    “CCA” wire because
    L
    this wire is significantly less conductive than
    Preouts
    pure copper wire. Only
    useRemote

    Power Wire.
    Control
    R
    Tinned copper wire (silver color) is acceptable
    as the tin-plating is only a very minor
    component of the wire.
    Fuse Requirements
    The installation of a fuse on the main power
    wire, within 18 wire inches (45 cm) of the positive
    battery terminal is vital to protect the wire and
    the vehicle from fire in the event of a collision
    or short-circuit. The fuse value at each power
    wire should be just high enough for all of the
    equipment being run from that power wire. Do
    not use a fuse with a value that far exceeds the
    total fuse rating of the electronics connected to
    the wire.
    If only the HD1200/1 is being run
    from that power wire, we recommend a
    100A fuse be used. MaxiFuse™ (big plasticbody fuse) types are recommended.
    If other amplifiers are also being powered
    from a main power wire and all the amplifiers
    together exceed 100 amps in total fuse rating,
    we recommend the use of an ANL (large-blade)
    fuse and holder at the battery plus a fused
    distribution block near the amplifiers. Each
    amplifier must be fused independently at the
    outputs of the fused power distribution block.
    We recommend appropriately rated MaxiFuse™
    fuses and a JL Audio fused distribution block.
    Please consult with your JL Audio
    dealer to make sure that the wire, fuse
    holder and fuse ratings are appropriate
    for your system’s needs. The safety of
    your installation depends on appropriate
    power connections and fuse protection.

    Ground Connection
    The chassis ground connection must be made
    using 4 AWG pure copper wire and should
    be kept as short as possible, while accessing a
    solid piece of sheet metal in the vehicle. The
    surface of the sheet metal should be sanded at
    the contact point to create a clean, metal-tometal connection between the chassis and the
    termination of the ground wire with a brass or
    copper power ring. For optimal grounding, we
    recommend the use of a JL Audio master ground
    lug (XB-MGLU). Alternatively, a sheet metal
    screw or bolt can be used with a star washer.

    Many vehicles employ small (10 AWG - 6 AWG)
    wire to ground the battery to the vehicle chassis
    and to connect the alternator’s positive
    connection to the battery. To prevent voltage
    drops, these wires should  be upgraded to 4
    AWG pure copper wire (or larger) when
    installing amplifier systems with main fuse
    ratings above 60A.
    Turn-On Wire
    The HD1200/1 uses a conventional +12V
    remote turn-on wire, typically controlled by
    the source unit’s remote turn-on output. The
    amplifier will turn on when +12V is present at
    its “Remote” input and turn off when +12V is
    switched off. If a source unit does not have a
    dedicated remote turn-on output, the amplifier’s
    turn-on lead can be connected to +12V via a
    switch that derives power from an ignitionswitched circuit.

    The HD1200/1’s “Remote” turn-on connector
    is designed to accept 18 AWG – 12 AWG wire. 18
    AWG is more than adequate for this purpose.
    To connect the remote turn-on wire to the
    amplifier, first back out the set screw on the
    bottom of the Power Connector Plug, using the
    supplied 2.5 mm hex wrench. Strip 1/2 inch
    (12mm) of wire and insert the bare wire into the
    receptacle, seating it firmly so that no bare wire
    is exposed. When using smaller wire, it may
    be necessary to strip 1 inch of insulation from
    the wire and fold the bare wire in half prior to
    insertion. While holding the wire in the terminal,
    tighten the set screw firmly using the supplied
    2.5 mm hex wrench, taking care not to strip the
    head of the screw and making sure that the wire
    is firmly gripped by the set screw.
    Amplifier Power Connector Plug
    To connect the power wires and the remote
    turn-on wire to the amplifier, unplug the power
    connector plug from the amplifier chassis (pull
    back firmly) and back out the set screws on
    the connector plug, using the supplied 4 mm
    hex wrench for the “+12 VDC” and “Ground”
    connections and the supplied 2.5 mm hex wrench
    for the “Remote” connection. Strip 3/8 inch (10
    mm) of insulation from the end of each wire and
    insert the bare wire into the receptacle on power
    connector plug, seating it firmly so that no bare
    wire is exposed. While holding each wire in place,
    tighten each set screw firmly, taking care not to
    strip the head of the screw.

    Never make power connections with a “live”
    wire. Always disconnect the negative battery
    post before making any connections or
    adjustments to a 12V power connection!

    AMPLIFIER MOUNTING OPTIONS
    The HD1200/1 has two mounting options to
    ease in installation.
    Standard Mounting

    ConTROL PAnel SECURITY CoVER
    The HD1200/1 features a Control Panel
    Security Cover. When installed, the cover ensures
    that your amplifier settings are not accidentally
    changed while creating a clean aesthetic for the
    amplifier and your installation. The control panel
    security cover is pre-installed at the factory and
    must be temporarily removed for access to the
    controls described throughout this manual.
    +12 VDC Ground

    The standard method of mounting requires
    removal of the four corner caps with the 4mm
    hex wrench included with your amplifier. Using
    appropriate mounting screws (not included),
    secure the amplifier in all four corners and
    replace the corner caps.
    Lateral Mounting Feet

    Lateral Mounting Feet are also included
    with your HD1200/1 to provide an alternative
    mounting option. Each mounting foot
    should be attached to the bottom of the
    amplifier by screwing the provided bolt into
    the bottom of the amplifier and up into the
    corner cap with the supplied 2.5mm hex
    wrench. Next, using appropriate mounting
    screws (not included), secure the amplifier
    by its four Lateral Mounting Feet.

    Check before drilling any holes in your vehicle
    to make sure that you will not be drilling
    through a gas tank, brake line, wiring harness
    or other vital vehicle system.

    8 | JL Audio - HD1200/1 Owner’s Manual

    The security cover is secured by a single 2.5
    mm hex-head screw at the far right of the panel.
    Loosen the hex-head screw to release the security
    cover (it is not necessary to completely remove the
    screw). To re-install the security cover once all
    adjustments have been made, insert the tongue on
    the cover’s left edge into the groove where the leftside heatsink meets the control panel, hinge the
    panel closed and secure the screw using the
    supplied 2.5 mm hex wrench. Do not overtighten
    the screw.

    AMPLIFIER INPuTS
    The HD1200/1 has a single input section
    consisting of a pair of RCA-type input jacks on
    the Connection Panel of the amplifier and a
    pair of input controls on the Control Panel of
    the amplifier: an “Input Voltage” switch and an
    “Input Sens.” rotary control.

    Inputs

    Preouts

    R

    R

    The HD1200/1 features stereo inputs, even
    though it is a mono amplifier. This has been
    done to permit the amplifier to sum stereo
    input signals to mono, which is particularly
    useful for driving subwoofers. Even if you
    have a dedicated mono subwoofer signal
    available or are feeding a left channel only or
    a right channel only into the amplifier, you
    must feed both inputs of the HD1200/1.
    Connection of only one RCA input will result
    in reduced power output, increased distortion
    and can cause the amplifier to overheat. To
    connect a mono signal to both inputs, use
    an RCA “Y-Adaptor” (sold separately).

    INPUT CONTROLS
    On the amplifier’s control panel you will find
    an “Input Voltage” range switch and a rotary
    control labeled “Input Sens.” (Input Sensitivity).
    These controls are designed to match the input
    sensitivity of the HD1200/1 to the specific signal
    source that is feeding it and must be adjusted,
    with care, following the procedures outlined in
    this manual. Failure to make correct adjustments
    can result in weak output, excessive distortion
    and/or undesirable noise in the audio output of
    Remotethe amplifier!
    Level
    Control

    “Input Voltage” Switch
    A wide range of signal input voltages can be
    accommodated by the HD1200/1’s differentialbalanced inputs (200mV – 8V RMS). This wide
    range is split up into two sub-ranges, accessible via
    the “Input Voltage” switch. The “Low” position
    on the “Input Voltage” switch selects an input
    sensitivity range between 200mV and 2V. This
    means that the “Input Sens.” rotary control will
    operate within that voltage window. If you are
    using an aftermarket source unit, with preamplevel outputs, this is most likely the position that
    you will use (regardless of what voltage output
    capability is claimed by the source unit).
    The “High” position on the “Input Voltage”
    switch selects an input sensitivity range between
    800mV and 8V. This is for use with speaker-level
    outputs from source units and small amplifiers
    found in many OEM (factory-installed) systems.
    To use speaker-level sources, splice the speaker
    output wires of the source unit or small amplifier
    onto a pair of RCA plugs for each input pair
    or use the JL Audio ECS Speaker Wire to RCA
    adaptor (XD-CLRAIC2-SW).

  • Page 6

    The output of the amplifier decreases for a
    given input voltage when the “Input Range”
    switch is placed in the “High” position. The
    output increases with the switch in the “Low”
    position. While this may sound counterintuitive, it is correct as described.
    “Input Sens.” Control
    Located to the left of the “Input Voltage”
    switch is a rotary control labeled “Input Sens.”.
    Once the appropriate “Input Voltage” range has
    been selected, this control can be used to match
    the source unit’s output voltage to the input stage
    of each pair of amplifier channels for maximum
    clean output. Rotating the control clockwise will
    result in higher sensitivity (louder for a given
    input voltage). Rotating the control counterclockwise will result in lower sensitivity (quieter
    for a given input voltage). To properly set the
    amplifier for maximum clean output, please refer
    to Appendix C (pages 18, 19) in this manual.

    CROSSOVER CONTROLS
    Crossovers are groups of electronic filters
    designed to control the frequency ranges
    that each speaker in a system will be tasked
    with reproducing. Proper crossover setup is
    critical to sound quality and reliability.
    The HD1200/1 has one filter, which can be
    configured as a high-pass filter (attenuates low
    frequencies) or as a low-pass filter (attenuates
    high frequencies). Additionally, the user can
    select from a shallow (12dB/octave) filter slope
    or a more aggressive (24dB/octave) slope.

    1) “Filter Mode” Control: this switch allows you
    to defeat or configure the filter into one of two
    filter types:
    “ Off”: Defeats the filter completely, allowing
    the full-range of frequencies present at the
    inputs to feed the amplifier. This is useful
    for systems utilizing outboard crossovers or
    requiring full-range reproduction.
    After using this procedure, you can then adjust
    the relative level by adjusting the input sensitivity
    downward, if it requires attenuation to achieve
    the desired system balance.
    Do not increase the “Input Sens.” setting for
    any amplifier in the system beyond the maximum
    level established during the procedure outlined in
    Appendix C (pages 18, 19). Doing so will result in
    audible distortion and possible speaker damage.

    “ HP” (High-Pass): Configures the filter
    to attenuate frequencies below the selected
    filter frequency. Useful for connection of
    component speakers in a bi-amplified system.
    “ LP” (Low-Pass): Attenuates frequencies
    above the selected filter frequency.
    Useful for connection of subwoofer(s)
    in a bi-amplified system.

    2) “ Filter Slope” Control: This switch allows you
    to select from two filter slopes:
    “12dB”: Configures the filter to attenuate
    frequencies above or below the selected
    filter frequency at a rate of 12 dB per octave
    (Butterworth alignment).

    INFRASONIC FILTER
    The “Infrasonic Filter” is a 24 dB/octave highpass filter, with a fixed cutoff frequency of 30 Hz.
    This filter is designed to conserve amplifier power
    and protect subwoofer systems, without audibly
    degrading the sub-bass output.

    “24dB”: Configures the filter to attenuate
    frequencies above or below the selected
    filter frequency at a rate of 24 dB per octave
    (Linkwitz-Riley alignment).
    Depending on the speaker system and the
    vehicle, different filter slopes may be required to
    produce a smooth transition between the sound
    of different speakers in the system.
    In high-pass mode, the sharper “24dB” setting
    will do a better job of protecting small speakers
    with limited power handling. In low-pass
    mode, the “24dB” setting can also help by more
    aggressively removing lower midrange output
    from a subwoofer system.
    The shallower “12dB” octave setting
    allows for more output overlap between
    the speakers being crossed over. In many
    cases, this will result in a smoother “blend”
    or transition between speaker systems.
    Experiment to find the slope or combination
    of slopes which best matches the acoustic
    requirements of your system.

    With ported enclosures, the use of the
    “Infrasonic Filter” is highly recommended to
    protect the speaker(s) from excessive excursion
    below box tuning.
    With sealed enclosures, the use of the filter
    is less necessary, but can still help protect the
    speaker system from excessive excursion.
    The “Infrasonic Filter” can be completely
    defeated by selecting the “Off” position on its
    switch. This bypasses all signal from flowing
    through the circuit.

    3) “Filter Freq. (Hz)” Control:
    This control selects the frequency at which the
    filter begins to attenuate the signal and refers
    specifically to the frequency at which output
    has been attenuated by -3dB.
    The filter frequency markings surrounding this
    rotary control are for reference purposes and are
    generally accurate to within 1/3 octave or better. If
    you would like to select the filter cutoff frequency
    with a higher level of precision, consult the charts
    in Appendix B (page 18) of this manual.

    OUTPUT POLARITY CONTROL
    Depending on the distance relationship of
    the mid-bass speakers and the subwoofers in a
    system, it can be desirable to reverse the polarity
    of the subwoofer system in order to produce
    a better transition between subwoofer and
    midbass speaker output. This is normally done
    by swapping the positive and negative wires
    connected to the subwoofer(s).

    Preamp Outputs
    The HD1200/1 incorporates a pass-through
    preamp output section, so that additional
    amplifiers can easily be connected to the same
    signal(s) feeding the HD1200/1. These preamp
    output signals are accessible via a stereo pair
    of RCA-type jacks, labeled “Preouts”, on the
    Connection Panel.

    The “Output Polarity” switch on the HD
    1200/1 allows you to quickly peform this polarity
    inversion without touching any wires. Simply
    flip the switch from the “0” (normal) to the “180
    deg.” (reversed) position.
    Neither switch position is “correct” for every
    system. Experiment to determine which polarity
    produces the best overall bass performance
    in your system, listening in particular to the
    mid-bass smoothness and impact to make your
    determination. If you change crossover slopes
    or crossover filter frequencies, you may need to
    revisit this control as these can affect the phase of
    the speaker systems in the overlap region.

    The term “pass-through” refers to the fact that
    the Preamp Output signals are not affected by any
    crossover filter or input sensitivity setting selected
    on the HD1200/1 (if the input signal is full-range,
    the Preamp Output will be full-range). These
    preamp output signals are buffered to prevent
    noise and are always preamp level, regardless of
    the level of signals feeding the HD1200/1’s inputs.

    REmote level control (OPTIONAL)
    With the addition of the optional Remote Level
    Control (HD-RLC), you can control the volume of
    the HD1200/1 from the front of the vehicle. This
    is particularly useful for subwoofer level control.
    The HD-RLC connects to the jack labeled
    “Remote Level Control” on the Connection
    Panel of the amplifier using a standard telephone
    cable (supplied with the HD-RLC).

    Speaker CONNECTIONS
    The HD1200/1 employs JL Audio’s exclusive
    Regulated, Intelligent Power Supply (R.I.P.S.)
    design. This sophisticated power supply allows
    the amplifier to produce its optimum power (1200
    watts x 1) over a wide range of supply voltage and
    speaker impedances.

    Control

    Remote
    Level
    Control

    When connected to the amplifier, the HD-RLC
    operates as follows. At full counter-clockwise
    rotation, the audio will mute completely. At full
    clockwise rotation the level will be the same as if
    the HD-RLC was not connected at all. In other
    words, it operates strictly as a level attenuator.

    The RBC-1 Remote Bass Control used with
    JL Audio Slash, Slash v2, e-Series, A-Series and
    G-Series amplifiers is NOT compatible with the
    HD Series amplifiers. If you attempt to connect
    an RBC-1 to an HD amplifer, the control will
    not work. You must use the HD-RLC controller.

    Unlike conventional amplifiers that require
    a specific impedance to produce optimum
    power, the R.I.P.S.-equipped HD1200/1 gives
    you the freedom to use a variety of speaker
    configurations that achieve final nominal
    impedances between 1.5 – 4Ω (without
    sacrificing power output or sound quality).
    The operation of the R.I.P.S. circuitry is
    entirely automatic and adjusts itself every time the
    amplifier is turned on. There are no user controls
    to configure. The system operates through
    multiple stages of impedance optimization,
    choosing the stage most appropriate to the actual
    impedance of the speakers you connect to it.

    If you connect a load higher than 4Ω nominal,
    power will drop by half with every doubling of
    impedance above 4Ω stereo. If you connect a
    load lower than 1.5Ω nominal, the amplifier
    protection circuitry activates a “safe” mode
    which reduces amplifier power to protect the
    circuitry from failure (the LED status indicator
    on the control panel will light up amber to
    indicate that this has happened). See page 14
    for details.

    13



  • Page 8

    Speaker loads below 1.5Ω nominal are not
    recommended and may cause the amplifier
    output to distort excessively.
    Speaker Connector Plugs
    To connect the speaker wires to the amplifier,
    unplug the speaker connector plug from the
    amplifier chassis (pull back firmly) and back out
    the set screws on the connector plug, using the
    supplied 2.5 mm hex wrench. Strip 3/8 inch (10
    mm) of insulation from the end of each wire and
    insert the bare wire into the receptacle on the
    speaker connector plug, seating it firmly so that
    no bare wire is exposed. While holding each wire
    in place, tighten each set screw firmly, taking care
    not to strip the head of the screw.

    You will notice that there are two sets of “+” and
    “–” connections on the plug. This is to facilitate
    multiple speaker wiring to the HD1200/1’s mono
    output. The two positive and two negative
    connections are connected in parallel inside the
    amplifier. Connecting two speakers, each to
    one set of positive and negative terminals, will
    result in a parallel speaker connection. If only
    connecting one pair of speaker wires, it is not
    necessary to use both sets of connections.

    “Status” LED / Protection Circuitry
    There is a single multi-color LED on the
    control panel of the amplifier to indicate the
    amplifier’s operating status. This LED’s behavior
    is as follows:
    1) Flashing Green: amplifier is powering up,
    audio output is muted.
    2) Constant Green: amplifier is on and
    functioning normally, audio output is active.
    3) Constant Red: lights to indicate that the
    amplifier has exceeded its safe operating
    temperature, putting the amplifier into a
    self-protection mode, which reduces the
    peak power output of the amplifier. The red
    light will turn green and the amplifier will
    return to full-power operating mode when its
    temperature returns to a safe level.
    3) Constant Amber (yellow): lights to indicate
    that the impedance of the speaker load
    connected to the amplifier is lower than its
    optimum load impedance range. When this
    light is on, a protection circuit engages and
    reduces the power output of the amplifier.
    The amber indicator will also light when a
    short-circuit is detected in the speaker wiring
    (this can be a short between the positive and
    negative speaker wires or between either
    speaker wire and the vehicle chassis).

    4) Alternating Red and Green: lights to indicate
    that the amplifier is experiencing a fault
    that may require service of the amplifier, its
    wiring or the vehicle’s charging system. Audio
    is muted when this fault occurs. The most
    likely cause of this fault is a low supply voltage
    condition. If battery voltage drops below 8.5
    volts at any point, the amplifier (except for the
    “Status” LED) will shut itself off to protect itself
    and the vehicle’s charging system. If the voltage
    drops below 6 volts, the “Status” LED will also
    turn off.
    The amplifier will turn back on automatically
    when voltage climbs back above 9 volts. This
    shut-down and turn-on behavior may happen
    in a rapid cycle when bass-heavy program
    material causes a weak charging system to
    momentarily dip too low. If this is happening
    in your system, have your charging system
    inspected to make sure it is working properly.
    If no problem is found with the supply
    voltage to the amplifier and you are
    still seeing alternating Red and Green
    on the “Status” LED, it is likely that the
    amplifier is suffering from an internal
    fault that requires factory service.

    Servicing your JL Audio Amplifier
    If your amplifier fails or malfunctions, please
    return it to your authorized JL Audio dealer so
    that it may be sent in to JL Audio for service.
    There are no user serviceable parts or fuses inside
    the amplifier. The unique nature of the circuitry
    in the JL Audio amplifiers requires specifically
    trained service personnel. Do not attempt
    to service the amplifier yourself or through
    unauthorized repair facilities. This will not only
    void the warranty, but may result in the creation
    of more problems within the amplifier.

    If you have any questions about the installation or
    setup of the amplifier not covered in this manual,
    please contact your dealer or technical support.

    Appendix C:
    Input Sensitivity Level Setting
    JL Audio amplifiers utilizing the Regulated
    Intelligent Power Supply (R.I.P.S.) allow
    delivery of their rated power when connected
    to any load impedance from 1.5 - 4Ω per
    channel and when connected to a charging
    system with any voltage from 11 - 14.5V.
    This design is beneficial for many reasons.
    One of these reasons is ease of setup.
    Because each JL Audio amplifier will
    always deliver the same amount of power
    within its operational range of impedances
    and supply voltages, the maximum,
    unclipped output is very predictable.
    This makes setting the gain structure via the
    input sensitivity controls very simple. Following
    the directions below will allow the user to adjust
    the input sensitivity of the amplifier(s) simply
    and easily in just a few minutes using equipment
    which is commonly available in installation bays.
    Necessary Equipment
    • Digital AC Voltmeter
    • CD with a sine-wave test tone recorded at
    0 dB reference level in the frequency range
    to be amplified for that set of channels
    (50 Hz for subwoofer channels, 1 kHz for
    a midrange application). The CleanSweep®
    Calibration Disc contains the appropriate
    test tones and is available for sale at
    http://store.jlaudio.com Do not use attenuated
    test tones (-10 dB, -20 dB, etc.).

    Do not increase any “Input Sens.” setting in
    the system beyond the maximum level
    established during this procedure. Doing so
    will result in audible distortion and possible
    speaker damage.

    The Nine-Step Procedure
    1) D
     isconnect the Speaker Connector Plug.
    2) T
     urn off all processing on the source unit
    (bass/treble, loudness, EQ, etc.). Set fader
    control to center position and subwoofer
    level control to 3/4 of maximum (if used
    to drive the HD1200/1). Disconnect
    the HD-RLC Remote Level Control
    temporarily (if one is being used).
    3) S witch the “Input Voltage” to “Low” and turn
    the “Input Sens.” control all the way down.
    4) Set the source unit volume to 3/4 of full
    volume. If the amplifier is being driven by a
    source unit’s dedicated subwoofer output, also
    adjust the source unit’s subwoofer level control
    to 3/4 of maximum output. This will allow for
    reasonable gain overlap with moderate clipping
    at full volume.
    5) Using the chart below, determine the
    target voltage for input sensitivity
    adjustment according to the nominal
    impedance of the speaker system
    connected to each set of outputs.

    Nom.
    Impedance

    6) Verify that you have disconnected the Speaker
    Connector Plug before proceeding. Play a
    track with an appropriate sine wave (within
    the frequency range to be amplified by each
    set of channels) at 3/4 source unit volume.
    7) Connect the AC voltmeter to the Speaker
    Output contacts of the amplifier.
    8)Increase the “Input Sens.” control until the
    target voltage is delivered. If excessive voltage
    is read with the control at minimum (full
    counterclockwise), switch the “Input Voltage”
    switch to “High” and re-adjust.
    9) Once you have adjusted the amplifier to its
    maximum unclipped output level, reconnect
    the speaker(s). The “Input Sens.” controls can
    now be adjusted downward if the HD1200/1
    requires attenuation to achieve the desired
    system balance.

    It will be necessary to re-adjust the “Input
    Sens.” for the affected channels if any equalizer
    boost is activated after setting the “Input
    Sens.” with this procedure. This applies to any
    EQ boost circuit, source unit tone controls or EQ
    circuits. EQ cuts will not require re-adjustment.

    Appendix D: TROUBLESHOOTING
    “How do I properly set the input sensitivity on my amplifier”

    Please r efer to Appendix C (pages 18, 19) to set the input sensitivity
    for maximum, low-distortion output.
    “My amplifier doesn’t turn on”

    Check t he fuse(s), not just visually, but with a continuity meter. It
    is possible for a fuse to have poor internal connections that
    cannot be found by visual inspection. It is best to take the
    fuse out of the holder for testing. If no problem is found with
    the fuse, inspect the fuse-holder.

    Check t he integrity of the connections made to each of the
    “+12VDC”, “Ground”, and “Remote” terminals. Ensure
    that no wire insulation is pinched by the terminal set screw
    and that each connection is tight.

    Check t o make sure there is +12V at the “Remote” connection of the
    amplifier. In some cases, the turn-on lead from the source unit
    is insufficient to turn on multiple devices and the use of a relay
    is required. To test for this problem, jump the “+12VDC” wire
    to the “Remote” terminal to see if the amplifier turns on.

    “I get a distorted / attenuated sound coming out of the speaker(s)”

    Check t he speaker wires for a possible short, either between the
    positive and negative leads or between a speaker lead and
    the vehicle’s chassis ground. If a short is present, you will
    experience distorted and/or attenuated output. The “Status”
    LED will turn amber (yellow) in this situation. It may be
    helpful to disconnect the speaker wires from the amplifier
    and use a different set of wires connected to a test speaker.

    Check t he nominal load impedance to verify that the amplifier is
    driving a load equal to or greater than 1.5 ohms.

    Check t he input signal and input signal cables to make sure signal
    is present at the “Amplifier Inputs” and the cables are not
    pinched or loose. It may be helpful to try a different set of
    cables and/or a different signal source to be sure.

    Reset t he amplifier by removing the power plug, then wait ten
    seconds and reconnect the power plug.
    “My amplifier’s output fluctuates when I tap on it or hit a bump”

    Check t he connections to the amplifier. Make sure that the
    insulation for all wires has been stripped back far enough to
    allow a good contact area inside the connector plugs.

    Check t he input connectors to ensure that they all are making good
    contact with the input jacks on the amplifier.

    “My amplifier shuts off once in a while, usually at higher volumes”

    Check y our voltage source and grounding point. The power supply
    of the HD1200/1 will operate with charging system voltages
    down to 9V. Shutdown problems at higher volume levels
    can occur when the charging system voltage drops below
    9V. These dips can be of very short duration making them
    extremely difficult to detect with a common DC voltmeter.
    To ensure proper voltage, inspect all wiring and termination
    points. It may also be necessary to upgrade the ground
    wire connecting the battery to the vehicle’s chassis and the
    power wire connecting the alternator to the battery. Many
    vehicles employ small (10 AWG - 6 AWG) wire to ground the
    battery to the vehicle’s chassis and to connect the alternator to
    the battery. To prevent voltage drops, these wires should  be
    upgraded to 4 AWG (or larger) when installing amplifier
    systems with main fuse ratings above 60A. Grounding
    problems are the leading cause of misdiagnosed amplifier
    “failures.”
    “My amplifier turns on, but there is no output”

    Check t he input signal using an AC voltmeter to measure the
    voltage from the source unit while an appropriate test tone is
    played through the source unit (disconnect the input cables
    from the amplifier prior to this test). The frequency used
    should be in the range that is to be amplified by the amplifier
    (example: 50 Hz for a sub bass application or 1 kHz for a full
    range / high-pass application). A steady, sufficient voltage
    (between 200mV and 8.0-volts) should be present at the
    output of the signal cables.

    Check t he output of the amplifier. Using the procedure explained
    in the previous check item (after plugging the input cables
    back into the amplifier) test for output at the speaker outputs
    of the amplifier. Unless you enjoy test tones at high levels,
    it is a good idea to remove the Speaker Connector Plugs
    from the amplifier while doing this. Turn the volume up
    approximately half way. 5V or more should be measured
    at the speaker outputs. This output level can vary greatly
    between amplifiers but it should not be in the millivolt
    range with the source unit at half volume. If you are reading
    sufficient voltage, check your speaker connections as
    explained below.

    Check to ensure that the speaker wires are making a good
    connection with the metal inside the Speaker Connector
    Plugs. The speaker wire connectors are designed to accept up
    to 12 AWG wire. Make sure to strip the wire to allow for a
    sufficient connection with the metal inside each terminal.
