Match M 5.4DSP micro Bedienungsanleitung Seite 35

The MATCH M 5.4DSP 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
1. Connecting the highlevel speaker inputs A -
D: The highlevel loudspeaker inputs (see
page 34, fig. 1, no. 1 - 4 and 11 - 14) can
be connected directly to the loudspeaker out-
puts of an OEM radio or aftermarket radio by
using the enclosed MATCH connection ca-
ble. It is not mandatory to use all highlevel
speaker inputs. It is sufficient if two of four
highlevel loudspeaker inputs are connected.
With the DSP PC-Tool software it is possible
to route the input signals to the nine output
channels individually.
Make sure that the polarity is correct. If one
or more connections have reversed polarity
it may affect the performance of the amplifi-
er. If this input is used the remote input (Re-
mote 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 A - D:
The loudspeaker outputs (see page 34,
fig. 1, no. 5 - 8 and 15 - 18) can be connect-
ed directly to the wires of the loudspeakers
by using the enclosed MATCH connection
cable. Never connect any of the loudspeak-
er cables to the chassis ground as this will
damage your amplifier and your speakers.
Ensure that the loudspeakers are correctly
connected (phase), i.e. plus to plus and mi-
nus to minus. Exchanging plus and minus
causes a total loss of bass reproduction. The
plus pole is indicated on most speakers. The
impedance per channel must not be lower
than 4 Ohms, otherwise the amplifier protec-
tion will be activated.
Attention: For connection, solely use only
the enclosed System Connector connection
cable or an appropriate cable harness from
the MATCH accessories program!
2. Connecting a digital signal source
If you have a signal source with an optical digi-
tal output you can connect it to the amplifier
using the appropriate input. In standard con-
figuration the manual activation via an optional
remote control is configured.
Alternatively you can activate the automatic
turn-on feature in the DCM menu of the DSP
PC-Tool software. The feature activates the
digital input as soon as a digital audio signal is
detected. The automatic turn-on function does
not work when a digital input is used. Therefore
it is mandatory to connect the remote input (Re-
mote In). A simultaneous use of the digital input
and the highlevel inputs is possible.
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
M 5.4DSP and your connected amplifiers. This
may cause severe damage to your speakers.
We strongly recommend to use an optional re-
mote control for adjusting the volume level of
the digital signal input!
Information: The MATCH M 5.4DSP can only
handle uncompressed digital stereo signals in
PCM format with a sample rate between 12 kHz
and 96 kHz and no Dolby-coded digital audio
stream!
3. Adjustment of the input sensitivity
Attention: It is mandatory to properly adapt
the input sensitivity of the M 5.4DSP to the
signal source in order to avoid damage to
the amplifier.
The input sensitivity can be optimally adapted
to the signal source using the DSP PC-Tool
software.
Input sensitivity is factory-set to 11 Volts. This is
definitely the best setting for most applications.
Only if the head unit / car radio doesn´t deliver
enough output level, the input sensitivity should
be increased.
Follow the subsequent steps to perfectly adapt
the amplifiers input sensitivity to your signal
source:
