Controls
1 Fuse (25 A × 3)
2 Battery terminal
3 Ground terminal
4 Power control terminal
Controls the unit ON/OFF.
NOTE
Controls the unit power. Be sure to connect it with all the systems.
5 Speaker 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.
6 RCA cable ground lead terminal
When using an RCA cable with a ground lead attached, connect the ground
lead to this terminal.
7 ID 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.
8 TO H/U terminal
After you have set the Master amplifier, connect it to the Center Unit.
9 REMOTE terminals
Used to connect to Slave amplifiers.
0 RESET 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.
@1 B.R.F. FREQUENCY control
Sets the rejection frequency when the "BRF" switch is set to "-6dB"/"-12dB".
