This switch allows to apply high-pass or low-pass
filtering to the speaker outputs.

2Battery terminal

3Ground terminal

4Power control terminal

Controls the unit ON/OFF.

NOTE

Controls the unit power. Be sure to connect it with all the systems.

5Speaker output terminals

•Stereo Connections:

When you wish to use the unit as a stereo amplifier, stereo connections are used.

The speakers to be connected should have an impedance of 2Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2Ω or greater for each channel.

•Bridged Connections:

When you wish to use the unit as a high-output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel

9 and the RIGHT channel · SPEAKER OUTPUT terminals.)

The speakers to be connected should have an impedance of 4Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4Ω or greater.

2CAUTION

The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result.

7LINE IN terminal

8LINE OUT terminal

The signal that’s input from the line input terminal is output.

9Power indicator

When the power is turned on, the Power indicator lights.

If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble. (See page 2)

0LPF FREQUENCY control

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

!HPF FREQUENCY control

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

@ISF (infrasonic filter) switch

Ultralow frequencies that cannot be reproduced even by a subwoofer speaker do not become sound but become unnecessary oscillations, which affect the sound by causing distortion, etc. Setting this switch to "15 Hz" or "25 Hz" cuts the frequencies below the respective frequency. This improves the reproduction performance

of the speakers by eliminating unnecessary oscillations which will not become sound.

frequencies than the frequency set with the

"HPF 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 "LPF

FREQUENCY" control.

The speaker output is automatically switched to

monaural (L+R).

$ OPERATION switch

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.)

%INPUT SENSITIVITY control

Set this control according to the pre-output level of the center unit connected with this unit.
