The
CH1/2 X-OVER switch
selects the required operation mode of the amplifier.
Position LP:
Lowpass mode (the higher frequencies will be eliminated. Adjustable by the lowpass controller.)
Position HP:
Highpass mode (the higher frequencies will be eliminate. Adjustable by the highpass controller.)
Position FULL:
Fullrange mode (the whole frequencies will be amplified).
5
The
LOW PASS controller
adjusts the cut-off point of the frequency range to above. The cut-off frequency is continuously
adjustable from 40 Hz to 150 Hz.

7
The
HIGH PASS controller
adjusts the cut-off point of the frequency range to below. The cut-off frequency is continuously
adjustable from 60 Hz to 1200 Hz (1.2 kHz).
8
The
LEVEL INPUT controller
adjusts the input sensitivity of the amplifier to align the audio signal from the head unit.
The input sensitivity is adjustable from 4 to 0.2 Volts.
The
LINE INPUT RCA jacks
must be connected with the RCA output jacks of the headunit.
9
The
LINE OUT RCA jacks
provide a linear fullrange audiosignal to supply an additional amplifier.
3
The
BASS BOOST controller
adjusts the bass boost enhancement continuously from 0dB to +12dB at 45 Hz.
The
High Level Input
is suitable to connect the amplifier inputs with speaker wires, if your headunit is not equipped with pre-
amplifier RCA outputs. Never use the High Level Input and the RCA inputs at the same time. This may damage the amplifier
seriously. Attend therefor the descriptions on page 28.
