English 5Controls1 Fuse (30 A × 2)2 Battery terminal3 Ground terminal4 Power control terminalControls the unit ON/OFF.NOTEControls the unit power. Be sure to connect it with all the systems.5 Speaker output terminalsAs this unit accepts speakers with a minimum impedance of 1 ohm, connectspeakers with 1-ohm or higher impedance to these terminals.2 CAUTIONThe rated input of the speakers should be no less than the maximum outputof the amplifier. Otherwise malfunction may result.6 RCA cable ground lead terminalWhen using an RCA cable with a ground lead attached, connect the groundlead to this terminal.7 ID NUMBER switchSets an amp identification number (ID) to be used for amplifier control fromthe 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 Slaveamplifiers. Do not duplicate these numbers.NOTEAfter you have changed ID numbers of amplifiers, turn Off the POWER switchof the Center Unit and turn it On again.8 TO H/U terminalAfter you have set the Master amplifier, connect it to the Center Unit.9 REMOTE terminalsUsed to connect to Slave amplifiers.0 RESET buttonResets the microprocessor of the unit.NOTEThe values you have set with the Amplifier Control are NOT reset.! LINE IN terminal@ LINE OUT terminalThe signal that’s input from the line input terminal is output.# Power indicatorLights when the POWER switch is turned On.The indicator flashes several seconds when the POWER switch is turned Onor when the Protection function is activated.$ INPUT SENSITIVITY controlSet this control according to the pre-output level of the center unitconnected with this unit.NOTEFor the pre-output level, refer to the in the instructionmanual of the center unit.% AMP CONT (amplifier control) switchUsed to bypass the circuit when you do not control the sound with theAmplifier Control.• ON position:Allows you to control the sound with the Amplifier Control.• OFF position:Bypasses the Amplifier Control circuit.NOTEAmplifier control is possible even while OFF.^ PHASE switchWhen this switch is set "180°" (Reverse) the speaker output phase is reversed.& BRF (band reject filter) switchWhen 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 rejectionallows to reduce resonance inside the vehicle compartment and standingwaves. (page 8)* ISF (infrasonic filter) switchWhen this switch is set to "ON", the inaudible, ultralow frequencies belowthe frequency set with the "ISF FREQUENCY" switch are cut off. This improvesthe reproduction performance of the speakers by eliminating unnecessaryoscillations which will not become sound.( ISF FREQUENCY switchSwitches the cutoff frequency when the "ISF" switch is set to "ON".) LPF(Low-Pass Filter) FREQUENCY controlThis control adjusts the frequency band output from this unit.@1 B.R.F. FREQUENCY controlSets the rejection frequency when the "BRF" switch is set to "-6dB"/"-12dB".(page 8)303001234567897% & * (^6# )8 9$04 5321 @!@1
