INSTALLATION INSTRUCTIONS
General:
Run the wiring so that RCA cables are at least 18“ away from power and
speaker cables. Keep RCA cables away from electrical devices in the vehicle
that can cause electrical noise, such as electric fuel pumps, emission control
modules and other on-board electronic modules.
Power and ground connections:
Use a sufficient gauge power cable and ground cable using the chart below
as reference to what size wire you require. Discus series amplifiers require at
least 10 mm
2
power wire. In a multi amplifier system, add the total value of
the manufacture recommended fusing to get your total system amperage.
Some applications may require multiple runs of power wire to meet the system
requirements. In multi amplifier systems it is advisable to mount a large enough
fuse right at the battery, and run one or multiple +12 volt power cables to a
fused distribution block near the amplifiers. It is then a simple matter to
connect the +12 volt terminal of each amplifier to the distribution block.
During this process, please ensure that the main power fuse is removed to
avoid shorting the electrical system. The main fuse must be within 30 cm of
the vehicles battery. Ground each amplifier with as short a ground lead as
possible directly to the vehicle chassis using at least 10 mm
2
wire or equivalent
to the size of the amplifiers’ power wire. Use a ground distribution block, if
you wish, but it is extremely important to keep the main ground lead from this
distribution block to the chassis as short as possible , not more than 30 cm.
The ground connection integrity to the chassis is very important, and the best
way to achieve a good, solid electrical and mechanical contact is to use a large
round crimp lug, crimped and soldered to the ground cable. The next step is
to scrape the paint off the vehicle chassis , slightly larger than the ground lug,
at the connection point. Drill a clearance hole in the chassis, the same size as
the lug hole, and use a bolt, spring washer and nut to securely fasten the
ground lug. Use petroleum jelly to coat the bolt/lug connection, to prevent
oxidization with time.
TIP: Use the same approach when installing head units, equalizers or any audio
equipment for that matter - run short individual grounds from each piece
directly to the vehicle chassis, to minimize ground loops and system noise. All
power, ground and speaker connections should be crimped and soldered for
reliability. Make sure that none of the cable insulation can chafe against
exposed metal in the vehicle, causing short circuits to the chassis.
Safe connection sequence:
After all cables are run, connect speaker wires to the speakers and amplifiers,
then run and plug in RCA cables. Next, connect all power, ground, and remote
turn on leads. Now connect all +12 volt cables to the amplifier/s and distribution
blocks and fuse holders. Finally, connect the main +12 volt cable to the battery,
with the main fuse removed, and we are almost ready to power up the system.
Power up the system:
The following procedure may seem like overkill, but there is nothing more
frustrating when turning on a system for the first time, and it does not work
properly immediately. First, make sure the head unit is off, and turn all level
controls to minimum (counterclockwise), including the head unit volume
control. Set all equalizers to 0 dB (no boost), and all crossover frequency
controls at approximate frequencies, as recommended by the loudspeaker
manufacturer. Set all input selector and crossover switches as required for the
application. Remove all amplifier fuses, and insert the main fuse at the battery.
If the fuse does not blow, you can insert the fuse in one of the amplifiers, and
we are ready to turn on the system. Turn the head unit on, insert a CD, or select
a radio station, and increase the head unit volume control. If the system sounds
fine, turn off the head unit, and install fuses in the remaining amplifiers, one
by one, till the complete system is powered up and functioning properly.
General:
At this point you are ready to get more specific on the settings for your amplifier.
High Pass:
-When in Hi Pass operation, this setting acts as a low frequency cut off for
your system reproduction. The point that you set it at cuts off any frequencies
from reproduction beyond this point. The 12 o’clock position is a great starting
point. EXAMPLE: If you adjust the High Pass to 100Hz, the amplifier will not
play frequencies below 100Hz but will play frequencies from 100Hz to the
chosen Low Pass frequency.
-When in Low Pass/Bandpass operation, this setting acts as a low frequency
cut off for your system reproduction aka Subsonic Filter. The point that you
set it at cuts off any frequencies from reproduction beyond this point. The 12
o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass
to 25Hz, the amplifier will not play frequencies below 25Hz but will play
frequencies from 25Hz to the chosen Low Pass frequency.
-When in Flat/Full operation, the High Pass crossover is bypassed.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-9dB. This
feature provides impact to your bass, but if not adjusted correctly, it can be
over used and cause damage to your speakers and amplifiers. It is best to slowly
turn this setting clockwise until the desired punch is felt. It is not recommended
to exceed the 12 o’clock position unless listening at a low volume or a low
recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the
right of the desired setting to be reproduced. Turning the potentiometer all
the way to the right is a great starting point. EXAMPLE: If you adjust the Low
Pass to 120Hz, the amplifier will not play frequencies above 120Hz but will
play frequencies from 120Hz to the chosen Hi Pass or Subsonic frequency.
-When in Hi Pass operation, this setting is bypassed.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the
system on. Next you should insert a CD or cassette that you are familiar with
to use as a reference, and turn the head unit volume control to about 80% of
its full setting. The system sound level will of course be very low, and the
following procedures will help you to match the amplifier input sensitivities
properly to the head unit output signal level. It is important to match the
amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can
be located in the Radio/CD manual. If the Radio/CD output sensitivity is 2 volts,
then adjust the amplifier LEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these
general guide lines:
Turn the level control up slowly, till you hear distortion, then back off a few
degrees on the control. If at any point your amplifier goes into protection, you
will need to turn the Level to the left a bit and then try again. If you reach a
point where the output does not increase, stop turning the Level control to
the right as the amplifier/speaker combo has reached its maxx output in this
application.
2 or 3 way active systems (all):
Always start with the bass, or low frequency amplifier as a reference, by turning
its control up to the point where distortion is audible, and back it off some.
Now adjust the level control for the highs or tweeter channels in a 2 way
active system, to balance the highs to lows. In a 3 way active system, match
the midrange level to the bass, and then the highs to the midrange and bass.
It may be necessary to perform a few iterations of the midrange and highs
level control settings to achieve a satisfactory sound balance.
