192.6 Wiring Your Audio SystemTypical input and output wirings are shown in Figure 2.6.INPUTS: Connect input wiring for both channels using either the RCA or theEuroblock input for each channel.OUTPUTS: You may use either low impedance or high impedance speakers.Always be sure to maintain the proper polarity when wiring speakers.Low Impedance Speakers should be driven using the +/- pins of the amplifier outputconnector. The minimum impedance an amplifier channel can drive is 4 Ohms.Therefore, you can connect up to four 16 Ohm speakers, two 8 Ohm speakers or one4 Ohm speaker to an amplifier output channel.High Impedance Speakers should be driven using the appropriate (70V or 100V) pinto speaker (+) and the COM pin to speaker (-) of the amplifier output connector. Theminimum impedance that can be driven from each output is provided in AppendixA. Note that the HI-Z switch must be ON in order to provide audio to the highimpedance outputs.WARNING: Do not connect to both low impedance speakers and high impedancespeakers from the same audio output channel.Figure 2.6 Wiring Audio SystemProfessional audio systemAUX OUTCSR-V ONLYHi-Z PHANTOMCH3 INPUTCH4 INPUTCH2 INPUTCH1 INPUT100V 70.7V COMMICLINEMICLINEMICLINEMICLINEMONO SUM MONO SUMVOXMONO SUM100-240 V~ 50/60Hz 40WCSMA 1120MADE IN MALAYSIACAUTION - TO REDUCE THE RISKOF ELECTRIC SHOCK, GROUNDINGOF THE CENTER PIN OF THE PLUGMUST BE MAINTAINED.5028384AMP OUT CLASS 2WIRINGCH2-4 IN / AUX OUTPRIORITYCD /OPTICALSPK 1 + 2 VIRTUALLEVELCSR-V |
