9Power indicator

Lights when the POWER switch is turned On.

The indicator flashes several seconds when the POWER switch is turned On or when the Protection function is activated.

0MODE switch (A/B/LINE OUT)

This switch selects the channel set in DSP settings (A, B, LINE OUT).

!Control knob

Allows you to switch between and determine Menu System items.

1Fuse (25 A × 3)

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 (A.ch/B.ch)

•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.

6RESET button

Resets the microprocessor of the unit.

7LINE IN terminal

8LINE OUT terminal

Outputs the audio signal set in DSP settings (stereo or center speaker/ subwoofer).

@DISP switch (SET/INFO)

•INFO position:

Sets <Status Information Display and Settings> (page 7).

•SET position:

Sets <DSP Settings> (page 8).

#INPUT SENSITIVITY control (A.ch/B.ch)

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

See <Input Sensitivity> (page 10) for details on setting.

NOTE

•For the LINE OUT level, refer to the <Specifications> in the instruction manual of the center unit.

•When A is selected with the INPUT SELECTOR switch, the control portion for cannot be used.

$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 the signal input to amplifier A with both amplifiers A and B.

%OPERATION switch (A.ch/B.ch)

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.)
