The MATCH UP 7DSP must be installed and con-
nected 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 System Connector 1
1.
Connecting the highlevel speaker inputs:
The highlevel loudspeaker inputs (see fig. 1,
page 22; 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 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 eight 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 amplifier.
If this input is used the remote input (
REM
)
does not need to be connected as the am-
plifier will automatically turn on once a loud
-
speaker signal is received.
2.
Connecting the loudspeaker outputs: The
loudspeaker outputs (see fig. 1, page 22;
no. 5 - 8 and 15 - 18) can be connected di-
rectly to the wires of the loudspeakers by
using the enclosed MATCH connection ca-
ble. Never connect any of the loudspeaker
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.
2.
Connecting the System Connector 2
Two subwoofers and a center speaker can be
connected to
System Connector 2
by using the
enclosed MATCH connection cable (see fig. 1,
page 22; no. 22 - 28). Never connect any of the
loudspeaker cables to the chassis ground as
this will damage your amplifier and your speak
-
ers. Ensure that the loudspeakers are correctly
connected (phase), i.e. plus to plus and minus
to minus. Exchanging plus and minus causes
a total loss of bass reproduction. The plus pole
is indicated on most speakers. The impedance
of each channel must not be less than 2 Ohms,
otherwise the amplifier protection will be acti
-
vated.
Attention:
Solely use the connection cable with
the 8-pole connector and flying leads which is
included in delivery!
3. Adjustment of the input sensitivity
The
Gain
control (page 20, item 14) is used to
adapt the input sensitivity to the output voltage
of the connected head unit / car radio. Adjust-
ments with this control do not affect the opti-
cal input! This is not a volume control, it´s only
for adjusting the amplifiers gain. The ex works
setting of the highlevel input sensitivi ty of the
UP 7DSP is the maximum coun ter-clockwise
position. This is definitely the best setting for
most applications. Only if the car radio doesn’t
deliver enough output level, the input sensitivity
should be increased by turning the
Gain
control
carefully clockwise (max. 6 dB).
4. Connecting a digital signal source
If you have a signal source with an optical digital
output you can connect it to the amplifier using
the appropriate input. In standard configuration
the MATCH UP 7DSP automatically activates
the used digital input if a digital audio signal is
detected. This function can be deactivated via
the DSP PC-Tool software. Alternatively you
can manually activate the digital input if you are
using the optional remote control.
The automatic turn-on circuit does not work
when the digital input is used. Therefore it is
mandatory to connect the remote input (
REM
).
Please note that it is possible to connect a
source to the digital input and the highlevel in-
