LINE INPUT
Connect the LINE INPUT RCA jacks with the head unit by using appropriate audio signal cables. If
only the channels FL and FR are occupied, the INPUT MODE button should be in switch position 2CH.
7
HIGH LEVEL INPUT
If your head unit does not have RCA preamp outputs, you can use the HIGH LEVEL INPUT. Connect
the loudspeaker cables of the head unit to the included cable harness.
8
LINE OUTPUT
The LINE OUTPUT RCA jacks provide a linear full-range audio signal for driving additional amplifiers,
such as the ZXR1200/1 monoblock.
9
LEVEL
These controllers determine the input sensitivity (adaptation to the output signal of the head unit) for
each channel pair.
11
INPUT MODE
The INPUT MODE switch is used to set whether the amplifier should be driven by the head unit with
only one stereo signal (2CH) or with two stereo signals (4CH). Only in switch position 4CH, the so-
called fader function of the head unit is effective.
In switch position 2CH, the input signal from FRONT (FL/FR) is routed to REAR (RL/RR) and only a
stereo signal on LINE INPUT FR/FL is necessary.
10
FRONT X-OVER MODE
This switch selects the desired operating mode of channel pair FRONT:
FULL:
Full Range mode - the entire frequency range is amplified
HP:
High Pass mode adjustable with HIGH PASS - frequency is limited downwards
DUPE:
All settings made on REAR are then also effective on FRONT. This is particularly useful if
you want to operate the channel pairs FRONT and REAR bridged with two subwoofers.
The bass level remote controller is then also effective on FRONT.
