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.

1Fuse (40 A x 2)

NOTE

If you can’t find the specified capacity fuse at your store etc., consult your Kenwood dealer.

2Battery terminal

3Power control terminal

Controls the unit ON/OFF.

NOTE

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

4Ground terminal

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.

6LINE IN terminal (A.ch/B.ch)

7LINE OUT terminal

These jacks output respectively the signals input to amplifiers A and B.

They always output the stereo signals regardless of the position of the "OPERATION" switch.

8THERMAL MANAGEMENT indicator

Lights this indicator when the internal temperature is high.

9PROTECTION indicator

Lights this indicator when the protection function is activated. (See page 2)

0Power indicator

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

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

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

The sensitivities of amplifiers A and B can be adjusted independently regardless of the position of the input selector switch.

NOTE

For the pre-output level, refer to the <Specifications> in the instruction manual of the center unit.

=HPF/LPF FREQUENCY control (A.ch/ B.ch)

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

~BASS BOOST FREQUENCY control (B.ch)

Sets the center frequency around which the low frequency range should be boosted.

!BASS BOOST LEVEL control (B.ch)

Sets the level by which the low frequency range should be boosted.

@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.

#OPERATION switch

The amplification methods of the signals input can be selected.

•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.)

$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 "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).
