INPUTS: There are three ways to connect an input signal to the amplifi er (Figure 2.13):

Connect an analog signal source to the Channel-1 amplifi er input.

Connect an AES/EBU digital signal source to the Digital Input IN connector.

NOTE: Crown provides a reference of wiring pin assignments for commonly used connector types in the Crown Amplifier Application Guide available at www.crownaudio.com.

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.
