Controls

NOTE

The control panel locates under the dressing cover. Remove the cover to access to its controls for adjustment. (See page 3)

1Fuse (25 A × 3)2Battery terminal3Ground terminal4Power 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.

6REMOTE terminal

Connects the Remote cable.

NOTE

Use the Remote cable of the accessory.

7LINE OUT FILTER switch

Changing over the audio signal output to the "LINE OUT" terminal.

ON position:

The audio signal adjusted when setting "LPF", "INPUT SENSIVITY" control and Bass boost is output to the "LINE OUT" terminal.

OFF position:

The audio signal input from the "LINE IN" terminal is output to the "LINE OUT" terminal (through output).

2CAUTION

The volume of the audio output to the "LINE OUT" terminal is different in "ON" and "OFF" position. Remember this when changing the "LINE OUT FILTER" switch from "ON" to "OFF".

8RESET button

Resets the microprocessor of the unit.

9LINE IN terminal0LINE OUT terminal

The audio signal set with the "LINE OUT FILTER" switch will be 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.

@Control knob

Allows you to switch between and determine Menu System items.

#PHASE switch

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

$ ISF (infrasonic filter) switch

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

%ISF FREQUENCY control

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

^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 7)

&B.R.F. FREQUENCY control

Sets the rejection frequency when the "BRF" switch is set to "-6dB"/"-12dB". (page 7)

*LPF(Low-Pass Filter) switch

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

•OFF position:

The entire bandwidth is output without filtering.

•ON position:

The filter outputs the band of lower frequencies than the frequency set with the "LPF FREQUENCY" control.

( 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.

) LPF(Low-Pass Filter) FREQUENCY control

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

*BOOST LEVEL (Bass boost level) control

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

( Power indicator) FREQUENCY (Bass boost frequency) control

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