1 FILTER switch (A.ch/B.ch)
This switch allows to apply high-pass or low-pass
filtering to the speaker outputs.
• HPF (High-Pass Filter) position:
The filter outputs the band of higher frequencies
than the frequency set with the FILTER
FREQUENCY control.
• OFF position:
The entire bandwidth is output without filtering.
• LPF (Low-Pass Filter) position:
The filter outputs the band of lower frequencies
than the frequency set with the FILTER
FREQUENCY control.
2 OPERATION switch (A.ch/B.ch)
This switch is used to select the operation mode
of the amplifier.
• 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.)
3 INPUT SELECTOR switch
This switch selects the input method of
the signals to be amplified by amplifiers A
and B.
• A B position:
Amplifies both of the signals input to
amplifiers A and B.
• A position:
Amplifies only signal input amplifier A with
both amplifiers A and B.
4 FILTER FREQUENCY control (A.ch/B.ch)
Sets the cutoff frequency when the FILTER switch
is set to LPF or HPF.
5 INPUT SENSITIVITY control (A.ch/B.ch)
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.
NOTE
For the pre-output level or the maximum power
output, refer to the <Specifications> in the
instruction manual of the center unit.
