Installation
The MATCH M 5DSP MK2 must be connected to
the head unit (car radio) as follows:
Caution:
Carrying out the following steps will re-
quire special tools and technical knowledge. In
order to avoid connection mistakes and / or dam
-
age, ask your dealer for assistance if you have any
questions and follow all instructions in this manual
(see page 17).
1. Connecting the highlevel loudspeaker in-
puts
The highlevel loudspeaker inputs (see fig. 1
page 23; no. 1 - 4 and 11 - 14) can be con-
nected directly to the loudspeaker outputs of an
OEM or aftermarket radio by using the enclosed
MATCH connection cable. It is not mandatory
to use all speaker inputs. It is sufficient if two of
four highlevel loudspeaker inputs are connect
-
ed. With the DSP PC-Tool software it is possible
to route the input signals to the five output chan
-
nels individually.
Make sure that the polarity is correct. If one or
more connections have reversed polarity it may
affect the performance of the amplifier. If this
input is used the remote input (
Remote In
) does
not need to be connected as the amplifier will
automatically turn on once a loudspeaker signal
is received.
2.
Connecting the loudspeaker outputs
The loudspeaker outputs (see fig. 1 page 23;
no. 5 - 8 and 15 - 18) can be connected directly
to the wires of the loudspeakers by using the
enclosed MATCH connection cable. Never
connect any of the loudspeaker cables with the
chassis ground as this will damage your ampli-
fier and your speakers. Ensure that the loud
-
speakers are correctly connected (phase), i.e.
plus to plus and minus to minus. Exchanging
plus and minus causes a total loss of bass re-
production. The plus pole is indicated on most
speakers. The impedance of each channel
must not be less than 4 Ohms, otherwise the
amplifier protection will be activated.
3.
Connecting a digital signal source
If you have a signal source with an optical digi
-
tal output you can connect it to the amplifier us
-
ing the appropriate input (
Optical Input
).
In standard configuration the MATCH
M 5DSP MK2 automatically activates the digital
input if a digital audio signal is detected. This
function can be deactivated via the DSP PC-
Tool software. Alternatively you can manual
-
ly activate the digital input if you are using an
optional remote control. The automatic turn-on
function does not work when the digital input is
used. Therefore it is mandatory to connect the
remote input (
Remote In
).
Please note that it is possible to connect a
source to the digital input and the highlevel
loudspeaker inputs at the same time.
Important:
The signal of a digital audio source
normally does not contain any information about
the volume level. Keep in mind that this will
lead to full level on the outputs of the MATCH
M 5DSP MK2 and your connected amplifiers.
This may cause severe damage to your speak
-
ers. We strongly recommend to use an optional
remote control for adjusting the volume level of
the digital signal input!
Information:
The M 5DSP MK2 can only han-
dle uncompressed digital stereo signals in PCM
format with a sample rate between 12 kHz and
96 kHz and no MP3- or Dolby-coded digital au-
dio stream!

Connection to power supply
Make sure to disconnect the battery before
installing the MATCH M 5DSP MK2!
Connect the +12 V power cable (yellow) to the
positive terminal of the battery. The positive wire
from the battery to the amplifier power terminals
needs to have an inline fuse at a distance of
no more than 12 inches (30 cm) from the bat-
tery. The value of the fuse is calculated from the
maximum total current input of the whole car
audio system.
If your power wires are short (less than 1m /
40”) then a wire gauge of 4 mm² / AWG 12 will
be sufficient. In all other cases we strongly rec
-
ommend gauges of min. 6 mm² / AWG 10!
The ground cable (black / same gauge as the
+12 V wire) should be connected to a common
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 pre
-
pared metal location on the vehicle chassis,
