Stereo: If the head unit / car radio provides one ste-
reo output, both speaker outputs are supplied with
the corresponding input signal.
Stereo Summed: In this mode a sum signal is gen-
erated by the input signals of the channels A and B.
Mono: If only the
Line Input
resp.
Highlevel Input
of channel A is connected, both amplifier channels
are supplied with this signal. In this mode the input
signal of channel A is routed to channel B. Please
consider that the balance control of the head unit
has the same effect on channel B as on channel A.
8
Status LED
The
Status LED
indicates the operating mode of the
amplifier. The LED lights up
green
when the ampli-
fier is ready for operation.
Orange
means that one
channel of the
Line Input
or
High level Input
is over-
driven. If the Clipping LED already lights up orange,
you have to reduce the input sensitivity via control 1
(
Input Sensitivity
) until the LED turns green.
A
flashing orange
light indicates that the internal
fuse is destroyed.
Note:
The fuses may only be replaced by identically
rated fuses (30 A) to avoid damage of the amplifier.
If the LED
flashes red
a malfunction has occurred.
A malfunction may have different causes as the
MATCH M 2FX is equipped with different protec-
tion circuits. These protections shut off the amplifi
-
er in case of overheating, over- and undervoltage,
short-circuit on loudspeakers and false connection.
Please check for connecting failures such as
short-circuits, wrong connections, wrong adjust-
ments and over temperature.
If the amplifier does not turn on it is defective and
has to be send to your local authorized dealer for
repair service. A detailed description of the malfunc-
tion and the purchase receipt has to be attached.

+12 V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 6 mm² / AWG 10.
10
GND
The ground cable should be connected to a com-
mon ground reference point (this is located where
the negative terminal of the battery is grounded
to the metal body of the vehicle) or to a prepared
metal location on the vehicle chassis i.e. an area
which has been cleaned of all paint residues. Rec-
ommended cross section: min. 6 mm² / AWG 10.
11
REM
The remote lead should be connected to the remote
output / automatic antenna (aerial positive) output
of the head unit / car radio. This is only activated
if the head unit is switched on. Thus the amplifier
is switched on and off together with the head unit.
This input needn’t to be assigned if the
Highlevel
Input
is used.
12
Auto Remote
The M 2FX will be turned on automatically if the
highlevel inputs are used or if a signal is applied to
the remote input (
REM
) terminal. The Auto Remote
switch allows to activate / deactivate the automatic
turn-on feature via the
Highlevel Input
. The feature
should be deactivated if there are e.g. disturbing
noises while switching on/off the amplifier.
Note:
If the automatic turn-on function is deactivat-
ed it is mandatory to use the remote input to power
up the amplifier! The highlevel signal will be ignored
in this case.
