2.6 Wiring Your Audio System
Typical input and output wirings are shown in Figure 2.6.
INPUTS: Connect input wiring for both channels using either the RCA or the
Euroblock 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 output
connector. 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 one
4 Ohm speaker to an amplifier output channel.
High Impedance Speakers should be driven using the appropriate (70V or 100V) pin
to speaker (+) and the COM pin to speaker (-) of the amplifier output connector. The
minimum impedance that can be driven from each output is provided in Appendix
A. Note that the HI-Z switch must be ON in order to provide audio to the high
impedance outputs.
WARNING: Do not connect to both low impedance speakers and high impedance
speakers from the same audio output channel.
