For us at MACROM the achievement of the topmost sound quality is one of our greatest concerns.
By the fact that you chose to buy the new programmable Digital Ready amplifier by MACROM we
realize that this is also your concern.
This unit offers 30 Watt max. 4-channel at 4 Ohm or 2x60 Watt max. when mono-bridged, with pure
and stable sound qualities.
We advise you to read the following instructions very carefully in order to get the maximum out of
the outstanding performances and the advanced features and functions of the 44.13. Please report
any problem to the nearest MACROM dealer.
PRECAUTIONS
1. The unit may be damaged by wrong lead connection, therefore read carefully the
instructions of this manual for the correct connection of the leads.
2. The last lead to be connected is the one to the positive (+) terminal of the battery;
connect this lead only after having completed and checked all other connections.
3. Due to the power of the 44.13 it is imperative that all connections are clean and
secure in order to avoid damage to the unit.
4, Be sure to install the amplifier in à position with good air circulation and good heat
dissipation.
5. In case of fuse replacement make sure to replace it with a fuse of the same amperage.
The use of fuses with the wrong amperage may seriously damage the components
of the unit.
If fuses blow more than once, carefully check all electrical connections. Also have your
car's voltage regulator checked. Do not attempt to repair the unit yourself. If repairs
are ever needed, take the unit to your MACROM dealer or to your nearest MACRCM
service station.
6. In order to obtain the best possible performance from this unit, make sure that the
temperature inside your car is within the range of -10° C and +60°C before you switch
the unit on. Good air circulation is essential to prevent heat build-up inside the unit,
FEATURES
4/3/2 CHANNEL OPERATION
The power of the 44.13 can be subdivided as follows:
a) 30 W RMS for each of the four output channels
b) 30 W AMS on two stereo channels, and 60 W RMS mono
c) 60 W RMS on two stereo channels
NO AMPERAGE LIMITATIONS
The amperage limitation circuits incorporated in traditional amplifiers may cause untimely
clipping and a low transient response. The absence of such circuits ensures a low T.1.M. effect,
an excellent transient response and a perfect sound quality.
INPUT MODE SELECTOR
This selector allows the user to choose between 2 or 4 input signals to the amplifier. €
OUTPUT MODE SELECTOR
This selector allows the user to specify the number and the configuration of the outputs.
INDEPENDENT SELECTORS FOR NRASSOWVED FORA
This control allows for independent selection of the Low Pass and High Pass crossover
frequencies at 80 or 120 Hz.
REMOTE ON/OFF
On switching the head unit on or off, the amplifier is automatically switched on or off.
RCA INPUT SENSITIVITY
The sensitivity adjustment of this new amplifier is positioned at 500 mV for optimum coupling with
other MACROM sources. However, the continuous adjustment from 100 mV to 2 V is possible
for easy coupling of other sources available on the market.
STATUS INDICATOR
This LED shows the current status of the amplifier:
GREEN fix: The unit works perfectly well.
GREEN blinking: The unit is in the protection mode, something is wrong.
WHITE: The unit is off.
TRIPLE PROTECTION
Your unit is provided with three different protection devices, as befits all high-end products:
SOFT START: the amp powers gradually in order to avoid damage to the speakers in case the
head unit is switched on with the volume control set to maximum.
OVERHEATING: in case of wrong installation the unit enters the protection mode before being
damaged. As soon as the temperature returns to normal values, the unit resumes "a
operation,
OUTPUT SHORT CIRCUIT: in case of a short circuit at the speaker outlets the unit enters the
protection mode in order to avoid serious damage to the end-stage transistors. Normal operation
Is resumed on eliminating the short circuit.
FINAL STAGE WITH DISCREET COMPONENTS (TRANSISTORS)
MOS-FET SUPPLY UNIT
The high power of the 44.13 is obtained by the use of a highly sophisticated C-MOS-FET supply
unit giving constant performance, A efficiency in favour of lower current-consumption. The
results are excellent performance, a linear and ample frequency response with high dynamics.
CAPACITIVE / INDUCTIVE POWER SUPPLY FILTER
This filter reduces radio frequency interferences (RFI) and cuts off system noises (i.e. the whine
of the alternator).

INSTALLATION
INSTALLATION (Fig. 1, page 3)
Due to the high power of the amplifier a great amount of heat is generated when the unit is in use.
Therefore, it is necessary to install the unit in a place with good air circulation or otherwise the
amplifier will enter the protection mode. The most suitable place for installation is the boot; obviously,
the unit should not be covered with carpet floor or similar. |
1. Place the unit at the point of installation and mark the position of the four securing screws
provided.
2. Drill the screw holes. | |
3. Place the amplifier in the correct position and secure it by means of the four tapping screws
provided.
NOTE: Connect the ground lead to a screw already provided on the chassis of the car (marked with
an * in the figure).

CONNECTIONS
CONNECTIONS:
1. Battery lead: Connect the terminal BATT 18 to the battery cable of the car by means of a
(yellow) cable of adequate section.
Do not connect this lead to circuits existing within the electric system of the car. In order to avoid
damage to the car it is imperative that this lead be fitted with a fuse (not provided) as near as
possible to the battery. This connection is the to be carried out last.
Remote switch-on lead: Connect the remote switch-on lead (REMOTE) or the control lead of
the power antenna coming from the head unit (blue) to the REMOTE (20 terminal of the amplifier.
NOTE: In case this lead is not connected, the amplifier will not be switched on when the head
unitis switched on. If your head unit is not fitted with an outlet for a power antenna, a quick-break
lever switch (SPST) shall be installed between the power source (+12 V) and the remote switch-
a lead and connected to the REMOTE 20 terminal so as to provide for manual switch-on of
e amplifier,
Ground lead: Secure the ground lead (black) to a clean spot on the car chassis and to the GND
terminal 19). Make sure that there is electric continuity between this spot and the negative
terminal of the battery. The ground cable should be as short as possible; in case more than one
amps are used, connect all ground connectors to one spot.
Fuse: In case of fuse replacement make sure to replace it with a fuse of the same amperage.
The use of fuses with the wrong amperage may seriously damage the components of the unit.
Speaker outlet terminals: Make sure to keep the right polarity and phase on connecting the
speakers (+ and -).
NOTE: Non adequately isolated wires should never come into contact with each other, with
metallic parts of the car or with the ground lead.
RCA input connectors: Connect the Pre output leads of your head unit to the RCA input
connectors by means of RCA extension cables (90.05-90.10-90.25-90.50 by MACROM).
Make sure to observe the right channel designation: left L (white) and right R (red).

select the position “4CH" and connect the outputs to the amplifier inputs marked with the letters
A (left), B (right), C (left) and D (right). Thus, the amplifier can be used as a 4-channel stereo
system, front section A and B and rear section C and D, by using the speaker outputs A, B, Cc
and D. You can then activate independently the different sections of the built-in electronic
crossover to obtain the High-Pass outputs A and B and/or the Low-Pass outputs C and D.
