This is a 4 channel amplifier including 2
stereo amplifiers in a body. One amplifier is
referred to as amplifier A and the other is
amplifier B. This unit is compatible with a
large variety of systems by combining the
switches and functions described in the
following.
1 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.
NOTE
For the pre-output level or the maximum
power output, refer to the "Specifications"
in the instruction manual of the center unit.
2 Bch BASS BOOST switch
Setting this switch to "ON" emphasizes the
bass.
You can use the BASS BOOST for amplifier
B only.
• ON position:
BASS BOOST is +6 dB.
• OFF position:
BASS BOOST is OFF.

3 FILTER switch
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.
4 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.)
5 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.
