always mention the recommended subwoofer type.
When using a subwoofer, we strongly recommend
to connect the PP 52DSP directly to a 12 Volt sour-
ce. Refer to connection instructions
in
section 3b,
page 19.
@
AUX
Input
This input automatically detects input signals
of
ex-
ternal devices like MP3-players, navigation devices,
etc. and switches to "AUX mode". If there is no si-
gnal for more than 2 seconds on the AUX 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

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
loudspeakers.
In
any case the warranty will be void!
@
Remote
Output
We strongly recommend to use this output for tur-
ning on/off additional amplifiers that are connected
to the line outputs
of
the PP 52DSP. 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.
@ USB
Input
Connect your personal computer to the PP 52DSP
using the provided USB cable. The required PC
software to configure this amplifier can be downloa-
ded from the Audiotec Fischer website.
Please note:
It is not possible to connect any USB
storage devices etc.

After erasing the setups from memory
the PP 52DSP will not reproduce any audio output
until a new setup is loaded.
®
MicroSD card reader
The microSD card reader allows the user to easily
copy car-specific setups to the amplifier. First you
have to download a sound setup (e.g. from our
website www.audiotec-fischer.com) and copy it to
a microSD card. After having inserted the microSD
card into the card slot
of
the PP 52DSP, the file will
be automatically copied to the internal memory
of
the amplifier. While the copy is
in
progress, the sta-
tus LED flashes red.
It
changes to green or orange
once the process is finished. Now the microSD card
can be safely removed.
Attention: Never remove the MicroSD Card while
the copy process is
in
progress.
The PP 52DSP 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.
You
can download the car-specific setup files to a
microSD card on www.audiotec-fischer.com.
Please be aware that it is not possible to modify the-
se setups with the PC-tool software! 15

Unique Features
of
the PP 52DSP
Power Save Mode
The Power Save Mode is incorporated
in
all car-
specific setups as well as
in
the basic setup
of
the
PC-tool software. It allows to significantly reduce
the power consumption
of
the PP 52DSP (or any
additional connected amplifier) once there's no in-
put 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 therefore the
PP
52DSP 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 52DSP and its "Remote Output"
will be turned off, thus reducing current draw to less
than 250 mA. 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

MCM power supply technology
This technology delivers a perfectly stabilized supp-
ly voltage for the internal amplifier stages indepen-
dent on any fluctuation
of
the battery voltage, even
during cranking the car's engine.
Like all other MATCH amplifiers the
PP
52DSP is
perfectly prepared for cars with start-/stop feature.
Please note:
Nevertheless the PP 52DSP 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).
MicroSD
The microSD card reader allows to easily configure
the DSP inside the amplifier without the need
of
directly connecting a personal computer. A large
number
of
car-specific setups is available for free
on www.audiotec-fischer.com. Simply download
your desired setup and copy it to any microSD card.
Finally insert the microSD card into the PP 52DSP
and the copy process will start automatically. After
that the amplifier is perfectly programmed to drama-
tically upgrade the sound quality
of
your car factory
audio system.
17

Installation
of
car specific sound setup files
The PP 52DSP offers the easy option
of
configuring the internal DSP amplifier to a specific vehicle type.
All you need is a MicroSD or MicroSDHC memory card. The card may contain other data such as photos
from a digital camera, however, note that it may contain only one "af1" and one "af2" setup file at a time.
The
3
most
important
steps:
www.audiotec-fischer.com
1. Access the Audiotec Fischer website. Select your
model ,
PP
52DSP amplifier" and finally your vehicle
make and model. Download and save the file to your
computer.
2. Transfer the downloaded setup onto your Mi-
croSD card. You'
ll
need less than 200 kB
of
free
memory space.
3. Finally, insert the card into the MicroSD slot
of
the PP 52DSP. The status LED will blink red for a
few seconds. When the blinking stops the setup file
is saved in the amplifier and the microSd card can
be removed

The MATCH
PP
52DSP
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
of
the MATCH cable harness,
see fig. 3
G)
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. There are two alternatives which are described
in
sections
3a
and 3b to connect the
PP
52DSP
to power. As long as a subwoofer is connected to
the PP 52DSP, we recommend to use alternative
3b (depending
on
wire gauge and fuse rating
of
the
vehicle's harness).
Short interrupts
in
music reproduction at high liste-
ning levels are an indicator for significant voltage
drops
on
the power supply due to insufficient vehi-
cle cable harness dimension.
3a. Power supply via vehicle cable harness:
In
this case the PP 52DSP will be directly powered
from the vehicles radio harness. Carefully check
its wire gauge and fuse rating first. Iffuse rating is
significantly lowerthan 20Athen we strongly recom-
mend
option 3b.
Depending on the vehicle type, the connections for
switched (ACC+) positive terminal and constant po-
sitive terminal can be different. The PP 52DSP must
not be powered using the switched positive terminal
as this might result
in
da-mage to the vehicle's elec-
tronic circuits. Verification
of
the right terminal must
be made prior to activation
of
the unit at connec-
tions
®
(yellow) and
®
(blue) with a voltmeter.
The constant positive wire is identified by a reading
of
12V even when the vehicle is turned off. After
measuring, connect cable
@to
the constant posi-
tive terminal (compare fig.
4).
If
you
are unable
to
identify
the
appropriate
wires, please
ask
your
dealer
for
help.
3b. Direct power supply via the battery:
Ifthe power supply
of
the PP 52DSP cannot be pro-
vided via the vehicle cable harness (max. 20A), you
have to connect it directly to the car battery.
To
do
so, disconnect
joints®
(ground) and
Q)
(+12V)
of
the MATCH harness (refer
to
fig.
5).
Next, the
ground cable (min. AWG14 I 2.5 mm2) should be
connected to a common ground reference point
(this is located where the negative terminal
of
the
battery is grounded to the metal body
of
the vehi-
cle), or to a prepared metal location
on
the vehi-
cle chassis, i.e.
an
area which has been cleaned
of
all paint residues.
Always
disconnect
the
car
battery's negative terminal before
you
execute
the
following
steps. Connect the +12V power ca-
ble (min.
AWG14/2.5
mm2) to the positive terminal
of
the battery. The positive wire from the battery to
the PP 52DSP harness connection needs to have
an inline fuse (20 A) at a distance
of
no more than
12
inches
(30 em)
from
the battery. Insulate the
now unused connections
of
the MATCH harness
with tape or other appropriate material.
You
can
now reconnect the car battery. If one
of
the cable
extensions PP-EC
11,
PP-EC25 or PP-EC40 will
be used, the separate power supply has to be con-
nected to the extension cable.
4.
Connect the MATCH harness to the MATCH PP
52DSP, see fig. 3
@.
Optimizing
the
amplifier
gain setting:
Turn the car radio
on
and the volume up gradual-
ly.
Maximum volume has been reached when lou-
dspeaker 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
52DSP. 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.
19

Caution:
The PP 52DSP amplifier typically has a higher
power output than the car radio itself. Most of
the OE speakers in the car will be able to handle
this extra power easily. Nevertheless please
take care when you crank up the volume. If you
hear strong distortion, please reduce the volu-
me to an appropriate level in order to avoid da-
maging your speakers.
Fig. 3 Connection of the amplifier to the car radio
Note -Cars equipped with MOST bus:
In cars equipped with MOST bus structure it is
mandatory to unplug the fiber-optic cable from
the original radio connector and insert it into the
radio connector of the MATCH cable harness,
which has a dedicated recess for this.
