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 a speaker 
in Bridge-Mono mode: 
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 Bridge-Mono mode.
or
2) Wire the speaker to terminals 1+ and 2+ in the 
Speakon connector (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.
