Control Input
This multi-functional connector is designed for
MATCH accessory products like the cable remote
control URC 2A. With this remote it is possible to
control several features of the amplifier. It consists
of two rotary controls and one toggle switch.
Note that it is necessary to activate a connected
URC 2A either by setting MODE switch no.6 to “ON”
position or by the appropriate command in the De-
vice Configuration Menu” of the PC-tool software.
As long as car-specific setups are used, the func
-
tions of the remote control are defined as follows
and cannot be changed:
CONTROL I: Adjusting the volume of the AUX input
– eliminates the need to adjust the volume on the
external source
CONTROL II: Adjusting the volume of the subwoo-
fer channels.
MODE switch: Toggling between the original sound
system
without any DSP processing and the optimized car
specific DSP sound setup for demonstration purpo
-
ses.
If the MODE switch no. 5 is set to „ON” position, the
function of the switch on the URC 2A will change.
In this case it is possible to manually activate the
AUX input.
If you create a DSP setup of your own then it will be
possible to change the remote’s functionality with
the PC-tool software.

MODE Switches / DIP Schalter
The six MODE switches allow adjusting the ampli-
fier gain and the functionality of the optional remote
control, which is especially important in combination
with car-specific setups where the PC-tool software
cannot be used.
MODE switch nos. 1 and 2 adjust the overall gain of
all amplifier channels including line outputs.
MODE switch nos. 3 and 4 adjust the gain of the
subwoofer channels
MODE switch no. 5 defines the function of the tog
-
gle switch on the remote control
MODE switch no. 6 activates/deactivates the remo-
te control.

Line Output
The two Line Outputs A and B are floating-ground
low-level outputs (max 3 Vrms) for connecting ad-
ditional power amplifiers. 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 amplifiers using the “Remote Output” of the PP
52DSP. Never directly control the external amps by
a signal from the ignition switch of your car!
