Initial start-up and functions
1
Auto Remote
The UP 7DSP will be turned on automatically if the
highlevel inputs of the System Connector 1 are
used or if a signal is applied to the remote input
(REM) terminal.
The Auto Remote switch allows to activate / de-
activate the automatic turn-on feature of the high-
level inputs of the System Connector 1. The feature
should be deactivated (Auto Remote = off) if there
are e.g. disturbing noises while switching on / off
the amplier.
Note: The automatic turn-on feature is activated ex
works (Auto Remote = on). If the automatic turn-on
function is deactivated it is mandatory to use the
remote input (REM) to power up the amplier! The
highlevel signal will be ignored in this case.
2
System Connector 2
This connector is used for connecting loudspeakers
and / or subwoofers. Solely use the connection ca-
ble with the 8-pole connector and ying leads which
is included in delivery to connect the loudspeakers /
subwoofers. The impedance per channel must not
be lower than 2 Ohms.
Caution: The use of other harnesses than the one
that is supplied with the amplier may cause severe
harm to the amplier, your head unit / car radio and
your loudspeakers. In any case the warranty will be
void!
3
Clipping LED
This LED lights up red if one of the four highlevel
inputs is overdriven. The LED has no function when
an input signal is applied to the digital input (Optical
Input) or to the MEC module.
4
System Connector 1
This connector is used as signal input from the OE
radio and as signal output of the amplier channels
A to D for connecting the loudspeakers. The imped-
ance per channel must not be lower than 4 Ohms.
Solely use this terminal only in combination with the
connection cable that is included in delivery of the
amplier or an appropriate cable harness from the
MATCH accessories program.
Caution: The use of other harnesses may cause
severe harm to the amplier, your head unit / car
radio and your loudspeakers. In any case the war-
ranty will be void!
5
Fuse LED
If a severe malfunction inside the amplier will blow
the internal fuses the LED lights up red. The fus-
es may only be replaced by identically rated fuses
(2 x 25 A) to avoid damage of the amplier.
6
+12 V
Connect the +12 V power cable to the positive ter-
minal of the battery. Recommended cross section:
min. 6 mm² / AWG 10.
7
GND
The ground cable 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 vehicle) or to a prepared metal lo-
cation on the vehicle chassis i.e. an area which has
been cleaned of all paint residues. Recommended
cross section: min. 6 mm² / AWG 10.
8
REM
This input has to be used to turn on / off the ampli-
er if the signal source which is connected to the
System Connector 1 is not activating the “automatic
turn-on” function (Auto Remote) or if the amplier
shall only be activated / deactivated by a remote
signal applied to the remote input.
The remote lead should be connected to the remote
output / automatic antenna (aerial positive) output
of the head unit / car radio. This is only activated
if the head unit / car radio is switched on. Thus the
amplier is switched on and off together with the
head unit / car radio.
Note: This input needn´t to be assigned if the high-
level inputs of the System Connector 1 are used.
9
USB Input
Connect your personal computer to the UP 7DSP
using the provided USB cable. The required
PC software to congure this amplier can be
downloaded from the Audiotec Fischer website
www.audiotec-scher.com.
Please note: It is not possible to connect any USB
storage devices.

Control pushbutton
The Control pushbutton allows the user to switch
between the two setup memory positions. To switch
between the setups the button has to be pressed
