BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wire kits. Ensure a sufcient prole section
(at least 0,75 mm
2
), the suitable fuse rating (the processor must be protected with an external fuse with 2 A) and the conductivity of the
cables when you purchase your wiring kit. Clean and remove rust-streaked and oxidized areas on the contact points of the battery and
the ground connection. Make sure that all screws are xed tight after the installation, because loose connections cause malfunctions,
insufcient power supply or interferences.

REM OUT
The with the processor connected turn-on signal (REM IN) can be forwarded to other devices such as ampliers. Connect then
the REM OUT cable of the processor with the remote port (REM) of the amplier. Use therefor a suitable cable with a sufcient
cross section (0,5 mm
2
). Hereby the processor and the amplier turns on or off with your head unit.
REM IN
Connect the turn-on signal (e.g. automatic antenna) or the turn-on remote signal of your head unit with the REM-IN cable of the
processor. Use therefor a suitable cable with a sufcient cross section (0,5 mm
2
). Hereby the processor turns on or off with your
head unit.
AUTO TURN ON
If you operate the processor with the HIGH LEVEL INPUT, you must not connect the REM IN cable. The processor detects by
the so called ”DC Offset” (a voltage increase to 6 volts on the high level speaker outputs) if the head unit is turned on and the
processor turns automatically on. As soon as the head unit is turned off, the processor shuts down automatically after approx.
one minute.
NOTE: The AUTO TURN ON usually works with 90% of all headunits, because they are equipped with the ”High Power” outputs.
Only with a few older headunits the AUTO TURN ON function is not applicable.
The REM OUT cable (see #1) can also be used in AUTO TURN ON operation.

+12V
Connect the +12V-cable with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufcient cross section (at least
0,75 mm
2
) and install an external in-line fuse (2 A). For safety reasons the distance between the fuseblock and the battery should
be shorter than 30 cm. Do not set in the fuse into the fuseblock until the installation is accomplished.

GND
Connect this GND wire with a suitable contact ground point on the vehicle’s chassis. The ground wire must be as short as possi-
ble and must be connected to a blank metallic point at the vehicle’s chassis. Ensure that this ground point has a stable and safe
electric connection to the negative “–”pole of the battery. Check this ground wire from the battery to the ground point if possible
and enforce it, if required. Use a ground wire with a sufcient cross section (at least 0,75 mm
2
) and the same size like the plus
(+12V) power supply wire.
