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

As this unit accepts speakers with a minimum impedance of 1 ohm, connect speakers with 1-ohm or higher impedance to these terminals.

2CAUTION

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

6RCA cable ground lead terminal

When using an RCA cable with a ground lead attached, connect the ground lead to this terminal.

7ID NUMBER switch

Sets an amp identification number (ID) to be used for amplifier control from the Center Unit.

Assign ID Number "0" to an amplifier when you use it as the Master amplifier. Assign ID Numbers "1" to "7" to amplifiers when you use them as Slave amplifiers. Do not duplicate these numbers.

NOTE

After you have changed ID numbers of amplifiers, turn Off the POWER switch of the Center Unit and turn it On again.

8TO H/U terminal

After you have set the Master amplifier, connect it to the Center Unit.

9REMOTE terminals

Used to connect to Slave amplifiers.

0RESET button

Resets the microprocessor of the unit.

NOTE

The values you have set with the Amplifier Control are NOT reset.

!LINE IN terminal

@LINE OUT terminal

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

#Power 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.

$ INPUT SENSITIVITY control

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

NOTE

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

%AMP CONT (amplifier control) switch

Used to bypass the circuit when you do not control the sound with the Amplifier Control.

•ON position:

Allows you to control the sound with the Amplifier Control.

•OFF position:

Bypasses the Amplifier Control circuit.

NOTE

Amplifier control is possible even while OFF.

^PHASE switch

When this switch is set "180°" (Reverse) the speaker output phase is reversed.

&BRF (band reject filter) switch

When this switch is set to "-6dB"/"-12dB", frequencies in the band set with the "B.R.F. FREQUENCY" control are rejected and eliminated. The band rejection allows to reduce resonance inside the vehicle compartment and standing waves. (page 8)

*ISF (infrasonic filter) switch

When this switch is set to "ON", the inaudible, ultralow frequencies below the frequency set with the "ISF FREQUENCY" switch are cut off. This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound.

( ISF FREQUENCY switch

Switches the cutoff frequency when the "ISF" switch is set to "ON".

) LPF(Low-Pass Filter) FREQUENCY control

This control adjusts the frequency band output from this unit.

@1B.R.F. FREQUENCY control

Sets the rejection frequency when the "BRF" switch is set to "-6dB"/"-12dB". (page 8)
