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

REM OUT
1
The with the processor connected turn-on signal (REM IN) can be forwarded to other devices such as amplifiers. Connect then
the REM OUT cable of the processor with the remote port (REM) of the amplifier. Use therefor a suitable cable with a sufficient
cross section (0,5 mm
REM IN
2
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 sufficient cross section (0,5 mm
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.
GND
3
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 sufficient cross section (at least 0,75 mm
(+12V) power supply wire.
+12V
4
Connect the +12V-cable with the +12V pole of the vehicle's battery. Use a suitable cable with a sufficient cross section (at least
0,75 mm ) and install an external in-line fuse (2 A). For safety reasons the distance between the fuseblock and the battery should
2
be shorter than 30 cm. Do not set in the fuse into the fuseblock until the installation is accomplished.
