If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of the amplifier. This works
13
in two ways, which can be set at the AUTO TURN-ON switch:
DC: This method only works if you use the amplifier's HIGH LEVEL INPUT. The amplifier then detects a voltage rise to 6 volts
when the head unit is turned on by a so-called "DC offset" and then turns on the amplifier.
VOX: Select this method when using the INPUT RCA jacks. The amplifier then detects a voltage increase in the incoming audio
signal when switching on the head unit via the attached RCA cable and then switches on the amplifier.
Note: As soon as the head unit is switched off again, the amplifier switches itself off.
The terminal for the amplifier turn-on (page 17# 2, REM IN/OUT) can now be used to supply additional amplifiers with a turn-
on signal. Simply connect the REM terminals of the two amplifiers and make sure that the other amplifier is in "normal" turn-on
mode, which means that the AUTO TURN ON function is disabled.
The BASS BOOST controller adjusts the bass boost continuously from 0 dB to +18 dB at 40 Hz.

NOTE: Always use this controller with care. A permanently too high bass boost could damage your speakers!

The REMOTE port is for connecting the cable of the included bass level remote controller. With this, the bass level can be e.g.
be adjusted from the driver's seat. Only use the supplied bass remote controller and the associated cable.

The PHASE SHIFT controller allows to adjust the phase between 0° and 180°. Hence, you are able to adjust the subwoofer
perfect to the vehicle's acoustics.
NOTE
Installation of RCA/Audio signal cables and power supply cables.
Ensure while installation not to lead the audio cables between the head unit and the amplifier together with the power supply wires
on the same side of the vehicle. The best is a real separated installation on the left and right cable channel of the vehicle to avoid
interferences on the audio signal. This stands also for the enclosed bass-remote wire, which should not be installed together with the
power supply wires.
