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
the amplifier itself, but not the car batteryDisconnect the negative
terminal of the battery before carrying out installation and
connection work.
Observe the vehicle manufacturer
bags, alarm systems, trip computers, vehicle immobilisers).
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
(battery
Fit the amplifier in a suitable location, e.g. beneath the seats or in the
trunk (Fig. 1). The mounting location must also be dry

passing cables through holes with sharp edges. Use loudspeakers with
an impedance of 2 to 4 Ω . Observe the max. power handling specifica-
tions (music output). Do not connect the loudspeakers to ground; only
use the terminals provided. The cross-section of the positive and nega-
tive cable must be at least 6 mm

. Run a
standard commercial positive cable to the battery and connect to the
fuse holder
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.

Connect remote amplifier connection to switchable
+12 V power source.
This enables the amplifier to be switched on and off with the radio’s On/
Off switch.
High-level inputs
The amplifier is equipped with high-level inputs to permit connection to
radios without preamp outputs (Fig. 5/5a). This enables direct connec-
tion to be made to the radio’s loudspeaker output.
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.
Important: Turning the gain control clockwise increases the input sen-
sitivity of the amplifier

not a volume control; an increase in volume is not achieved in
the maximum position, even if this subjectively appears to be the case.
The system merely increases the volume more quickly when the volu-
me is turned up on the radio.
T
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.
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. The same applies to the
negative (-) terminals. The left-hand amplifier channel must also be con-
nected to the left-hand loudspeaker and the right-hand amplifier chan-
nel to the right-hand loudspeaker. Loudspeaker

to use the amplifier for one or more subwoofer(s) or a mid-range spea-
ker. In this configuration the amplifier sums the right-hand and left-hand
channels, delivering a single channel (mono) output.
Note: The amplifier can sum the right- and left-hand signal information
only if both the right- and left-hand RCA

overheat or switch off. This can lead to permanent damage of the
unit.
Note: If the amplifier is to be used in the tri-mode configuration, the
crossover frequency selector switch must be set to „Flat“ in order to
make the full frequency range available.
