Initial start-up and functions
1
Output channels E - H
You can directly connect a MATCH subwoofer to
this output, by using four of the eight amplier chan-
nels of the PP 82DSP. Please make sure that in this
case the output signal of all these four channels is
identical.
Alternatively you can congure each channel indi-
vidually for other purposes via the PC tool software
(e.g. center speaker or fully active congurations).
For the latter case a connector with ying leads is
included in delivery of the PP 82DSP.
2
Line Output
The two Line Outputs A and B are oating-ground
low-level outputs (max 3 Vrms) for connecting ad-
ditional power ampliers. Specially designed „Ba-
lanced Dual Audio Transformers” avoid any ground-
loops that may cause undesired alternator noise.
Please make sure that you always turn on/off exter-
nal ampliers using the “Remote Output” of the PP
82DSP. Never directly control the external amps by
a signal from the ignition switch of your car!
Important: The outputs G and H deliver the same
audio signal as the speaker outputs G and H. Any
changes in the setup via the PC-Tool software will
always have the same effect on the speaker outputs
and line outputs of the channels G and H!
3
Optical Input
Optical input in SPDIF format for connection to si-
gnal sources with a digital audio output. The sam-
pling rate of this input must be between 6 and 192
kHz. The input signal is automatically adjusted to
the internal sample rate.
In order to activate this input the optional cable re-
mote control URC 2A is necessary.
Notice: This amplier can only handle stereo input
signals and no Dolby-coded digital audio stream.
4
AUX Input
This input automatically detects signals of external
devices like MP3-players, navigation devices, etc.
and switches to “AUX mode”. If there is no signal for
more than 2 seconds on the AUX input, the amplier
automatically switches back to the radio signal.
If the MODE switch no. 5 is set to “on” position, the
automatic input detection will be deactivated. In this
case it is possible to manually switch to AUX input
using the optionally available remote control URC
2A.
5
System Connector
Please use this terminal only in combination with
the cable harness that is included in the delivery of
the amplier. Never ever use any other harnesses
to connect the MATCH PP 82DSP to your car radio.
Caution: The use of other harnesses than the one
that is supplied with the amplier may cause severe
harm to the amplier, your car radio and your lou-
dspeakers. In any case the warranty will be void!
Important: This connector does not allow connec-
ting the amplier to the car’s battery. It is mandatory
to use the terminals (7) and (9) which are described
in the following.
6
Fuse
If a severe malfunction inside the amplier will blow
the internal fuses the LED lights up red.
During normal operation this LED will remain off.
7
+12V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended wire gauge: at
least AWG 8 or 10 mm².
8
Rem Out
We strongly recommend to use this output for tur-
ning on/off additional ampliers that are connected
to the line outputs of the PP 82DSP. This is essential
to avoid any undesired pop noises during DSP boot
or software update process. Additionally this output
will be turned off when the “Power Save Mode” (see
page 17) of the amplier is active.
9
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.
10
MODE Switches / DIP Switches
The six MODE switches allow adjusting the ampli-
er gain and the functionality of the optional remote
control when the PC-tool software is not used for
setting up the amplier.
MODE switch nos. 1 and 2 are to adjust the overall
gain of all amplier channels including line outputs.
MODE switch nos. 3 and 4 are to adjust the gain of
