1FILTER 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.

2OPERATION 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.)

3INPUT 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.

4FILTER FREQUENCY control (A.ch/B.ch)

Sets the cutoff frequency when the FILTER switch is set to LPF or HPF.

5INPUT 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.
