Dear Customer,
Congratulations on your purchase of this high-qua-
lity MATCH product.
With the PP 82DSP, MATCH is setting new stan-
dards
in the evolving plug & play market.
General installation instructions for MATCH
components
To prevent damage to the unit and possible injury,
read this manual carefully and follow all installati-
on instructions. This product has been checked for
proper function prior to shipping and is guaranteed
against manufacturing defects.
Before starting your installation, disconnect
the battery's negative terminal to prevent
damage to the unit, fire and/or risk of injury. For
a proper performance and to ensure full warranty
coverage, we strongly recommend to get this pro-
duct installed by an authorized MATCH dealer.
Install your PP 82DSP in a dry location with suf-
ficient air circulation for proper cooling
of the
equipment. The amplifier should be secured to
a solid mounting surface using proper mounting
hardware. Before mounting, carefully examine the
area around and behind the proposed installati-
on location to insure that there are no electrical
cables or components, hydraulic brake lines or any
part
of the fuel tank located behind the mounting
surface. Failure to do so may result
in unpredictable
damage to these components and possible costly
repairs to the vehicle.
We wish you many hours
of enjoyment with your
new MATCH PP 82DSP.
Yours,
AUDIOTEC FISCHER
General instruction for connecting the PP
82DSP amplifier
The PP 82DSP may only be installed in vehicles
which have a negative ground electrical system.
Any other system may cause damage to the
amplifier and the electrical system
of the vehicle.
Use only the provided MATCH cable for con-
nection of the
PP 82DSP. The use of other
cables can result in damage of the ampli-
fier, the head unit I radio or the connected
loudspeakers!
Prior to installation, plan the wire routing to
avoid any possible damage to the wire harness.
All cabling should be protected against possible
crushing or pinching hazards. Also avoid routing
cables close to potential noise sources such as
electric motors, high power accessories and other
vehicle harnesses.
The fuse may only be replaced by an
identically rated fuse (2 x 25 A) to avoid damage
of the amplifier.

Initial start-up and functions
CD Output channels E - H
You can directly connect a MATCH subwoofer to
this output, by using four
of the eight amplifierchan-
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 configure each channel indi-
vidually for other purposes via the PC tool software
(e.g. center speaker
or fully active configurations).
For the latter case a connector with flying leads is
included in delivery
of the PP 82DSP.
@ 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/offexter-
nal amplifiers 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 effecton the speakeroutputs
and line outputs
of the channels G and H!
@ 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 amplifier can only handle stereo input
signals and no Dolby-coded digital audio stream.
@) AUX Input
This input automatically detects signals of external
devices like MP3-players, navigation devices, etc.
and switches to "A
UX mode ". Ifthere is no signal for
more than 2 seconds on theAUX input,the amplifier
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.
@ System Connector
Please use this terminal only in combination with
the cable harness that is included in the delivery
of
the amplifier. 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 amplifier may cause severe
harm to the amplifier, your car radio and your lou-
dspeakers.
In any case the warranty will be void!
Important: This connector does not allow connec-
ting the amplifier to the car's battery. It is mandatory
to use the terminals (7) and (9) which are described
in the following.
@ Fuse
Ifa severe malfunction inside the amplifier will blow
the internal fuses the LED lights up red.
During normal operation this LED will remain off.
(J) +12V
Connect the +12 V power cable to the positive ter-
minal
of the battery. Recommended wire gauge: at
leastAWG 8
or 10 mm2.
@ Rem Out
We strongly recommend to use this output for tur-
ning on/off additional amplifiers 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 offwhen the "Power Save Mode" (see
page 17)
of the amplifier is active.
@ 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.
@ MODE Switches I DIP Switches
The six MODE switches allow adjusting the ampli-
fier gain and the functionality
of the optional remote
control when the PC-tool software is not used for
setting up the amplifier.
MODE switch nos. 1 and 2 are to adjust the overall
gain
of all amplifier channels including line outputs.
MODE switch nos. 3 and 4 are to adjust the gain
of
15

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.
@
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
function
of
the switch on the URC 2Awill 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 configure this amplifier can be down-
loaded from the Audiotec Fischer website. Please
16
note: It is not possible to connect any USB storage
devices.
@
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"
I
,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
in
the PC tool software the mode switch function
of
the

optional remote control URC 2A as "setup switch"
as well.
Notice: Firmware and software updates are availa-
ble
on our website www.audiotec-fischer.com
The PC tool software will automatically install the
latestfirmware on the last selected memory location
if your device is not up-to-date.

Power Save Mode
The Power Save Mode
is
incorporated
in
the ba-
sic setup. It allows to significantly reduce the power
consumption of the
PP
82DSP (or any additional
connected amplifier) once there's no input signal for
more than 60 seconds. Please note that
in
many
up-to-date cars with "CAN" or any other internal bus
structures it may happen that the radio (and therefo-
re
the
PP
82DSP as well) remains "invisibly" turned
on
for up to 45 min. after leaving the car!
Once the "Power Save Mode
is
active the output
stages of the
PP
82DSP and its "Remote Output"
will
be
turned off, thus reducing current draw to less
than 250
rnA.
The amp will turn again to full operati-
on
within 2 sec. if a music signal is applied.
It
is
possible
to
either modify the turn-off time
of
60
sec. or completely deactivate the "Power Save
made" via the PC-tool
Class
HD
and P
3
S
power
supply
technology
For the first time the
PP
82DSP combines the ad-
vantages
of
a Class H technology with the principle
of
a class D amplifier. The result
is
an
unsurpassed
efficiency, which easily outperforms any conventio-
nal class D amplifier.
The new P
3
S power supply technology controls the
internal supply voltage for the output stages as a
function
of
the amplitude of the input signal. Thus
the average power dissipation of the amplifier
is
dramatically reduced.
Like all other MATCH amplifiers the
PP
82DSP is
perfectly prepared for cars with start-/stop feature.
Please note:
Nevertheless the
PP
82DSP has
an
undervoltage
protection. If the supply voltage drops below 9.6
volts for more than 5 seconds the amplifier goes to
"Protect mode" (Status LED lights up red)
in
order
to avoid any further discharge ofthe car's battery.

The MATCH
PP
82DSP
must
be connected
to
the head
unit
(radio) as
follows:
Caution: Carrying out the following steps will
require special tools and technical knowledge.
In
order to avoid connection mistakes and/or dama-
ge, ask your dealer for assistance if you have any
questions and follow all instructions
in
this manual
(see page 13).
1.
After removing the radio from the dash using
appropriate tools, disconnect the vehicle harness
from the radio. Next, connect the vehicle harness
to the male connector ofthe MATCH cable harness,
see fig. 3 (!)
Depending
on
your car
an
additional car-specific
adaptor may be required.
A list
of
all cars and the respective adaptors can
be
found
on
www.audiotec-fischer.com.
2.
Connect the female connector of the MATCH
cable harness or the car-specific adaptor to the ra-
dio, see fig. 3
®.
3.
In
case of the
PP
82DSP the included MATCH
cable harness cannot and must not be used for the
power supply. Always directly connect the massive
screw terminals ofthis amplifier to your car's battery
using appropriate wires (AWG
8/1
0 mm
2
or better).
Never use the power leads of the car radio itself!
Though the
PP
82DSP only has a limited average
power consumption, it may draw very high currents
(up to 50A) for the fraction of a second due to its
dynamically controlled internal power supply.
Important: You
may
risk
a severe damage
of
your
car
radio and
other
electronic
components
inside
your
vehicle
or
even a cable fire
if
you
use the
car
radio harness
for
the
power
supply
of
the
PP
82DSP!
Make
sure
to
disconnect
the battery before in-
stalling
the
PP
82DSP!
Connect the +12V power cable to the positive termi-
nal
of
the battery. The positive wire from the battery
to the
PP
82DSP power terminals needs to have
an
in
line fuse (50 A) at a distance of
no
more
than
12 inches (30 em)
from
the battery. If your power
wires are short (less than 1 m
/40")
then a wire gau-
ge
of
6
mm
2
I AWG 10 will be sufficient.
In
all other
cases we strongly recommend gauges of 1
0 - 16
mm
2
I AWG 6 -
8!
The ground cable (same gauge
as the +12V wire) 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.
4.
Connect the MATCH harness to the MATCH
PP
82DSP, see fig. 3
®·
Optimizing the
amplifier
gain setting:
Turn
on
the car radio and the volume up gradually.
Maximum volume has been reached when loud-
speaker distortion becomes audible.
To
increase
volume range of the radio use the MODE switches
nos. 1 and 2 (refer to page 17) to reduce the overall
gain of the
PP
82DSP. If your radio
is
at maximum
volume without any distortion being audible, you
can use the MODE switches to increase the am-
plifier overall gain by
+2
dB.
Be
careful when using
this function.
Caution:
The
PP
82DSP
amplifier
has a
significantly
hig-
her
power
output
than the
car
radio itself.
Most
of
the
OE
speakers in the
car
will
not
be able
to
handle
this
extra
power
permanently.
As
long
as
you
do
not
replace the
original
speakers
by
lou-
dspeakers
with
higher
power
handling please
be
very
careful when
you
crank
up
the volume.
If
you
hear
strong
distortion,
please reduce the
volume
to
an appropriate level in
order
to
avoid
damaging
your
speakers.
