10. icated subwoofer amplifier Unlike other amplifiers the Class operates as a singe channel and cannot be bridged Don t be fooled by the outputs Two outputs are used strictly for convenience and are paralleled internally on the amplifier This means that if both outputs are used with one driver each the amplifier sees the same load as if the sarre drivers are connected to Only one output terminal See diagram below SUBWOOFER SPEAKER OUTPUT P FUSE Pira 9 e B GND Ji 2 69 4OHM 4OHM SUBWOOFER SUBWOOFER In both diagrams the amplifier sees a 2 ohm load FIG 3 SPEAKER CONNECTIONS WIRING SUBWOOFERS DUAL AMPS When using dual amplifiers io power one subwoofer the Positive terminal of the Subwoofers voice coil is connected the positive terminal of the MASTER Amplifier and the Negative terminal of the subwoofers voice coil is connected to Positive terminal on the SLAVE Amplifier This procedure will allow the total power of both amplifiers to be added together and act like a single powerful amplifier Please check that your subwoofer power handling capabilities are not exceeded when hooking two amplifiers to it CAUTION Always check your speaker load with a multi meter before hooking up to the amplifier These digital amplifiers are only 1 ohm stable Any Impedance load smaller than 1 ohrn will damage the amplifier Such Damage is not covered under warranty either so
11. itivity adjustment is to allow the amplifier to work with many different brands of head units It allows input signal to vary between 200 millivolts to 6 volt from the head unit or other signal processor Start by setting the sensitivity adjustment to the MIN 6 volts Using a cassette or compact disc that you are familiar with turn on head unit to the 3 4 volume setting Slowly turn up sensitivity adjustment towards the MAX 200 millivolts using a flat head screw driver Stop turning on the onset of distortion and turn back just a slight The 3 4 volume setting is now the maximum volume for the head unit The goal is to keep the level control to the lowest setting yet still have enough signal to drive the amplifier This is done to prevent over driving the amplifier and to keep system noise to a minimum It is important not over drive speakers at point of distortion this will cause permanent damage to the speakers Also if the amplifier itself is over driven it could be damaged BASS function can be selected to increase low frequency response output or decrease frequency response output The BASS function will be working at only OFF or L PF position The BASS is adjustable from 0 12dB boost at 50Hz FRONT PANEL PHD2050 PHD2200 CROSSOVER 6 6 q MIN 20Hz 50Hz OdB 12dB 50Hz 250Hz FULL 80Hz 1 2kHz LEVEL SUBSONIC BASS L P F H P F BOOST FRONT PANEL PHD4050 r CROSSOV
