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 2Aeither 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.
Notice: Ifyou activate the remote control
in
the PC
tool software, the DIP switches no.5 and no.6 on
the PP 82DSP will automatically be disengaged.
To
reactivate them you have to cancel this option
in
the
PC tool software.
As long as the functions
of
the remote control have
not been changed
in
the PC tool software these are
defined as follows:
CONTROL
I:
Adjusting the volume
of
the AUX input
-eliminates the need to adjust the volume on the
external source
CONTROL
II:
Adjusting the subwoofer volume.
Each output that has been defined as a subwoofer
channel
in
the PC tool software will then be affected
by this control.
MODE switch: Toggling between the original sound
system without any DSP processing and your opti-
mized car specific DSP sound setup for demonstra-
tion purposes. The DSP and the output channels
E - H will be deactivated when the switch on the
remote is pressed.
Ifthe MODE switch no. 5 is set to ,ON" position, the

@
Status LED
The status LED indicates the operation mode
of
the
amplifier. Green means that setup 1 (af1) is loaded,
orange means that setup 2 (af2) is loaded. Ifit lights
up red constantly, the undervoltage protection is
active.
A flashing red light indicates that no setup is loaded.
In
that case please load a new setup via the PC tool
software or the internal microSD card reader.

Control pushbutton
The control pushbutton allows the user to toggle
between two loaded setups ,af1" and ,af2".
To
switch between the setups, the button has to be
pressed and held for approx. 1 second. Switching
is indicated by a singular red flash
of
the Status
LED. Pressing the button for 5 seconds completely
erases the internal memory. This is indicated by a
constant flashing
of
the Status LED.
Attention: After erasing the setups from memory
the PP 82DSP will not reproduce any audio output
until a new setup is loaded.
@
MicroSD card reader
The Micro SO card reader can be used to download
firmware and software updates as well as complete
DSP setup files containing all DSP settings. After
having inserted the MicroSD card into the card slot
of
the PP 82DSP, the file will be automatically co-
pied to the internal memory
of
the amplifier. While
the copy
is
in
progress, the status LED flashes red.
It changes to green or orange once the process is
finished. Now the microSD card can be safely re-
moved.
Attention: Never remove the MicroSD Card while
the copy process is
in
progress.
The PP 82DSP can manage two different setup
files. They are marked with the file extensions ,.af1"
I
,ac1" (stored
in
memory 1
of
the amplifier) or ,.af2"

,ac2" (stored
in
memory 2
of
the amplifier). Please
note: Do not store more than one "af1" or ,ac1" and
one "af2" or ,ac2" setup file on the microSD card
at a time.
With the control pushbutton you can toggle between
the two setups. Alternatively you can configure
