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 amplier. 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 Conguration Menu” of the PC tool software.
Notice: If you 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
dened 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 dened 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 specic 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.
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. The AUX input is activated when the switch
on the remote is pressed.

USB Input
Connect your personal computer to the PP 82DSP
using the provided USB cable. The required PC
software to congure this amplier can be down-
loaded from the Audiotec Fischer website. Please
note: It is not possible to connect any USB storage
devices.

Status LED
The status LED indicates the operation mode of the
amplier. Green means that setup 1 (af1) is loaded,
orange means that setup 2 (af2) is loaded. If it lights
up red constantly, the undervoltage protection is
active.
A ashing 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 ash of the Status
LED. Pressing the button for 5 seconds completely
erases the internal memory. This is indicated by a
constant ashing 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.
15
MicroSD card reader
The Micro SD card reader can be used to download
rmware and software updates as well as complete
DSP setup les containing all DSP settings. After
having inserted the MicroSD card into the card slot
of the PP 82DSP, the le will be automatically co-
pied to the internal memory of the amplier. While
the copy is in progress, the status LED ashes red.
It changes to green or orange once the process is
nished. 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
les. They are marked with the le extensions „.af1“
/ „ac1“ (stored in memory 1 of the amplier) or „.af2“
/ „ac2“ (stored in memory 2 of the amplier). Please
note: Do not store more than one “af1” or „ac1“ and
one “af2” or „ac2“ setup le on the microSD card
at a time.
With the control pushbutton you can toggle between
the two setups. Alternatively you can congure in
the PC tool software the mode switch function of the
