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.
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.
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.
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.
