Introduction
Congratulations on your purchase of a high-quality MP
amplifier
which delivers superlative reproduction quality
upgrading an existing system or using the MP
a new system, you are certain to notice immediate performance
benefits!
Recommendation:
A
installation will maximise the overall performance of your audio system.
We recommend that you have our product installed professionally
you decide to install the amplifier yourself, however
these instructions carefully
Finally
music in your car that sustained sound levels above 100 dB can damage
your hearing and may even result in total hearing loss. Modern high-
performance systems and high-quality loudspeaker configurations are
quite capable of generating noise levels above 130 dB
Safety precautions
Instructions for installation and connection
Fit a fuse in the amplifier power line no more than 30 cm from the vehicle
battery
between it and the power amplifier.

terminal of the battery before carrying out installation and
connection work.
Observe the vehicle manufacturer

The final stage must be installed professionally for reasons of safety
The mounting surface must be suitable for the screws provided, and
must provide firm support.
When drilling holes, take care to avoid damage to vehicle components

. Run a
standard commercial positive cable to the battery and connect to the
fuse holder. Use cable grommets when passing cables through holes
with sharp edges. Bolt a standard commercial negative cable to a ground
point free of induced noise (car body bolt, body panel) - not to the nega-
tive battery pole. Clean the contact surface of the ground point down to
bare metal and coat with antiseize graphite petroleum.
Integral fuses
The integral fuses within the amplifier protect the final stage and the
entire electrical system in the event of a fault. Never bridge fuses or
replace fuses with a higher current rating.

Gain control
The gain control enables the input sensitivity of the final stage to be
matched to the output voltage of your car radio preamp output.
The range of adjustment extends from 0.3 V to 4 V
to 2 V for Blaupunkt car radios.
Adjust the input sensitivity in accordance with the manufacturer
fications when connecting the amplifier to other radios.

MP
This facility enables the amplifier to be used simultaneously with stereo
satellite speakers (mid-range and tweeter) and a mono subwoofer
The connections are somewhat more complicated in this case, as they
require the use of passive crossover networks (not supplied with the
amplifier) which divide the frequency ranges between the various
loudspeakers. The requisite connections can be taken from the diagrams
below
If you do not wish to purchase and connect the components separately
a number of ready-assembled tri-mode crossover networks are availa-
ble.
CAUTION: In tri-mode (combined mono/stereo mode) the amplifier must
be presented with a load of at least 2 Ohms (stereo satellite speakers)
or 4 Ohms (mono subwoofers). Lower loads cause overheating of the
amplifier and may damage it permanently
Loudspeaker connections
(If the amplifier is to be connected in a bridged mode, proceed with the
section “Bridged loudspeaker connections”.)
As with any audio component, connection of the amplifier and speakers
with the correct polarity is essential for good bass reproduction. Ensure
therefore when connecting that the positive (+) amplifier terminal is con-
nected to the positive (+) loudspeaker terminal.
