4 EnglishControls / Indicator2 3 51(W)2040104 6This is a 4 channel amplifier including 2stereo amplifiers in a body. One amplifier isreferred to as amplifier A and the other isamplifier B. This unit is compatible with alarge variety of systems by combining theswitches and functions described in thefollowing.1 INPUT SENSITIVITY controlSet this control according to the pre-outputlevel of the center unit connected with thisunit, or to the maximum power output ofthe genuine-accessory car stereo.The sensitivities of amplifiers A and B canbe adjusted independently regardless of theposition of the input selector switch.Use the diagram on the right as a guide.For the pre-output level or the maximumpower output, refer to the “Specifications”in the instruction manual of the center unit.2 Bch BASS BOOST switchSetting this switch to "ON" emphasizes thebass.You can use the BASS BOOST for amplifierB only.• ON position:BASS BOOST is +6 dB.• OFF position:BASS BOOST is OFF.3 FILTER switchThis switch allows to apply high-pass orlow-pass filtering to the speaker outputs.• HPF (High-Pass Filter) position:The filter outputs the band of higherfrequencies than the frequency set with theFILTER FREQUENCY control.• OFF position:The entire bandwidth is output withoutfiltering.• LPF (Low-Pass Filter) position:The filter outputs the band of lowerfrequencies than the frequency set with theFILTER FREQUENCY control.4 OPERATION switchThe amplification methods of the signalsinput to amplifiers A and B can be selectedindependently according to the setting ofthis switch.• STEREO position:The amplifier can be used as a stereoamplifier.• MONO (Lch) position:Amplifies the signal input from the left sideonly. Set to this position and make bridgedconnections to use as a high-powermonaural amplifier. (The input right signal isnot output.)5 INPUT SELECTOR switchThis switch selects the input method of thesignals to be amplified by amplifiers A andB.• A B position:Amplifies both of the signals input toamplifiers A and B.• A position:Amplifies only signal input amplifier A withboth amplifiers A and B.NOTE
