OUTPUTS: Use Class 2 output wiring. There are two ways to wire the amplifi er output connectors for Bridge-Mono mode:

1)Wire the speaker across the red binding post of each channel (Figure 2.14). Do not use the black binding posts when operating in Bridge-Mono mode.

2)Wire the speaker only to the top Speakon® connector as shown in Table 3 and Figure 2.14.
