INTRODUCTION
Macrom, who strive continually to achieve the ultimate in sound quality, have traditionally
been a synonym for the very best in European sound and music reproduction. The fact that
you have chosen this product means that you share our opinion. After reading this manual you
will be in an even better position to appreciate all the advanced features in this new Amplifier.
This Amplifier incorporates an exceptional set of technical features, and for this reason all
signal sources, loudspeakers and interconnecting elements must also be of the very highest
quality. We recommend the use of Macrom high quality main subassemblies, electronic
crossovers, loudspeaker systems, connecting leads and accessories. Similarly, because
integration of these products is an extremely complex task, we advise you to leave the
installation of this amplifier to your authorised MACROM dealer.
This Amplifier has no commands or controls that can be adjusted by the user, so read this
manual very carefully, to familiarise yourself with the special features and functions of your
new MACROM product. If in any doubt, contact your authorised MACROM dealer.
PRECAUTIONS
1. Just one faulty connection could damage the unit, so read the connection instructions
provided in this manual very carefully.
2. Connect the battery lead to the (+) battery terminal last of all, and only after having
completed and checked all the other connections.
3. Take care to install the amplifier in a position where both good air circulation and heat
dissipation are guaranteed.
4. The fuses must always be replaced with fuses of identical ampere rating in order to
prevent serious damage to the components. You should also first have the voltage
regulator of your car checked. Never attempt to repair the unit yourself. Entrust any
necessary repairs to a MACROM distributor or your local MACROM service centre.
5. To ensure the highest possible performance from this unit, try to obtain a temperature of
between -10°C and +60°C inside your car before switching on the amplifier.

1 • RCA input connectors: To connect the Pre output leads of the main unit to the amplifier
input. These inputs control the final stages.
2 • Adjustment of the gain of the Input: Adjusts input sensitivity of amplifier,
which can vary between 200 mV and 4V.
To adjust sensitivity, proceed as follows:
a)Set the volume control of your unit to 3/4 of its maximum output
b)Adjust the amplifier input gain controls until the maximum possible acoustic
pressure has been obtained without any distortion.
3 • Stereo/Mono switch: changes the output mode of the amplifier between
Stereo and Mono. If Mono is selected, the corresponding Left (mono) input is
used to operate the amplifier.
4 • Crossover switch: selects the output mode of the amplifier by activating the Low-pass or
High-pass filter.
a)Flat: the amplifier will reproduce the complete audio
range in relation to the signal applied to the input.
b)Low-pass: activation of the low-pass filter, i.e.
determination of the finishing-point of the low frequencies
present at the outputs .
c)High-pass: activation of the low-pass filter, i.e.
determination of the starting-point of the high frequencies
present at the outputs.
5 • Continuous adjustment/control of the Low-Pass or High-Pass
frequencies: once the low-pass or high-pass filter is inserted, the crossover
frequency can be adjusted in continuous mode between 30 Hz and 600 Hz.

6 • Speaker connectors: Outputs for connecting the loudspeakers.
The amplifier allows the loudspeakers to be connected with a minimum impedance of 2 Ohm
for a channel in stereo configuration, and with an impedance of 4 Ohm for a "bridged" mono
connection.
If the 3 channel configuration is to be used, the total impedance should not exceed the
minimum value of 2 Ohm.
Make sure that the polarity of the connection between the loudspeakers is correct. Do not

7 • Fuses: When replacing fuses, make sure that they are replaced with fuses of the same
ampere rating. Use of the wrong type of fuse could seriously damage the components.
8 • + BATT connector: Connect the positive "+" of the battery directly, by means of a fuse
located nearby, and use a lead having a sufficiently large cross-section to allow passage of the
current. Do not connect this terminal to the car's own electrical circuit.
9 • REMOTE-ON connector: Connect this to the remote-on start-up output lead (remote
starting switch) or to the automatic antenna wire running from the main unit. It will now be
possible to turn the amplifier on and off from the main unit.
allow inadequately insulated leads to come into contact with Ground,
any metallic parts of the car, or with each other.
10 • GND connector: Attach this Ground connector, using a lead of adequate section, to a
clean point on any metallic part of the car chassis, if possible to an already-installed screw.
Never attach this clamp directly to the negative point of the battery, which could give rise to an
unpleasant buzzing noise while the car is being driven.
11 • Check control indicator: This LED indicates the amplifier functioning status.
WHITE: The unit is switched off
GREEN: The amplifier is functioning perfectly
RED: the unit is in a state of protection.
The amplifier is equipped with three protection devices:
- Overheating: If errors have been made during installation, and the amplifier overheats, the
unit will enter into a state of protection before any damage can occur. Once the temperature
returns to normal and the errors have been rectified, the unit will automatically start to function
normally once again.
- Overloading: If several loudspeakers have been connected to the amplifier and the total
impedance drops below the 1 Ohm limit that it can handle, the amplifier goes into a state of
protection. The main unit will have to be switched off and on again in order to restore the
amplifier to normal functioning.
- Short circuit in an output: In the case of a short circuit in the loudspeaker outputs, the unit will
go into a state of protection to avoid serious damage to the final transistors. Normal
functioning will be restored when the short circuit has been dealt with and the main unit
switched on again.
