Typical input and output wiring is shown in Figure 2.5.
IMPORTANT: Turn off the amplifier and unplug its power cord.
INPUTS: Choose one of these options:
• Connect analog input wiring for both channels.
• Connect an AES/EBU digital signal to the AES/EBU connector.
• Connect a CobraNet network cable with a digital signal to the Network
connector (CN models only).
OUTPUTS: Maintain proper polarity (+/–) on output connectors. Use
Class 1 output wiring.
Figure 2.5 shows how to wire stereo speakers to the 5-way binding
posts. Connect Channel 1 loudspeaker's positive (+) lead to Channel 1
positive (red) terminal of amp; repeat for negative (–). Repeat Channel 2
wiring as for Channel 1.
To wire stereo speakers to the Speakon connectors, use one of these
methods:
Method 1 (Table 1 and Figure 2.6): Wire one Speakon cable connector
to two speakers. Insert the Speakon cable connector into the amplifier's
top Speakon connector.
Method 2 (Table 2 and Figure 2.7): Plug the Channel 1 speaker into the
Channel 1 (top) Speakon connector, and plug the Channel 2 speaker
into the Channel 2 (bottom) Speakon connector.
