HI LEVEL INPUT
If your head unit does not have RCA preamp outputs, you can use the HI LEVEL INPUT. To do this,
simply connect the loudspeaker cables of the head unit to the included 10-pin cable harness.
NOTE: If you can hear background noises when using the high level inputs, connect the ground con-
nection of the cable plug to a ground point on the vehicle.

INPUT MODE
This switch can be used to set whether the amplifier should be controlled with just one stereo signal
(2CH) or with two stereo signals (4CH) from the head unit. The fader setting on the control unit is only
effective in switch position 4CH.
In switch position 2CH, the input signal is routed from the channel pair CH1/2 to CH3/4. This means
that only a stereo signal is required at the inputs CH1/CH2.

POWER/PROTECT
If the LED lights up in blue, the amplifier is ready for operation. If the LED lights up in red, there is a
malfunction. Refer in this case to chapter
TROUBLE SHOOTING
on page 26.

BASS LEVEL CONTROLLER
This 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 bass level remote controller only works in LPF/BPF mode (Low-Pass/Band-
pass) on channel pair CH3/4, in DUPE mode also on channel pair CH1/2.
