XLS Series Power Amplifiers
2 Setup
2.6.2 Bridge-Mono Mode
INPUTS: Use a custom “Y” adapter cable, wired to split the signal and invert the polarity for the Channel 2 amplifier input as shown in Figure
2.10.We recommend you label the ends of the Y adapter to help make sure to connect the correct end to each amplifier input.
Connect the Y adapter between the signal source and each amplifier input (Figure 2.11).
NOTE: Crown provides a reference of wiring pin assignments for commonly used connector types in the Crown Amplifier Application Guide available at www.crownaudio.
OUTPUTS: There are two ways to wire the ampli- fier output connectors for
1) Wire the speaker across the red binding post of each channel (Figure 2.11). Do not use the black binding posts when the amp is being oper- ated in
2) Wire the speaker only to the top Speakon con- nector as shown in Table 3 and Figure 2.12.
NOTE: The Channel 1 and 2 level controls MUST be set to identical settings when operating the XLS amplifier in Bridge- Mono mode.
