INPUT SENSITIVITY control
Set this control according to the pre-output
level of the center unit connected with this
unit, or to the maximum power output of
the genuine-accessory car stereo.
The sensitivities of amplifiers A and B can
be adjusted independently regardless of the
position of the input selector switch.
Use the diagram on
the right as a guide.
For the pre-output level or the maximum
power output, refer to the “Specifications”
in the instruction manual of the center unit.

OPERATION switch
The amplification methods of the signals
input to amplifiers A and B can be selected
independently according to the setting of
this switch.
• STEREO position:
The amplifier can be used as a stereo
amplifier.
• MONO (Lch) position:
Amplifies the signal input from the left side
only. Set to this position and make bridged
connections to use as a high-power
monaural amplifier. (The input right signal is
not output.)

FILTER switch
These switches allow filtering of the
speaker output signals.
• HPF(High Pass Filter) position:
Only frequencies of 150Hz or higher are
output. (Frequencies below 150Hz are cut.)
• LPF(Low Pass Filter) position:
Only frequencies of 80Hz or lower are
output. (Frequencies above 80Hz are cut.)
The Lch and Rch will be mixed before
output even if the operation switch is set to
STEREO.
• OFF position:
The original sound without filtering is
output.
