Bridge Mono Mode - QSC CMXa Serie Manual Usuario

Bridge Mono Mode

What it is
Bridge Mono mode combines the power of both amp channels into one speaker, resulting in
twice the voltage swing, four times the peak power, and approximately three times the sustained
power of a single channel. This mode uses Channel 1's input, attenuation control, input fi lter, and
clip limiter; Channel 2's dip switch settings should be in the OFF position, the attenuation control
should be at maximum attenuation
When to use it (or not)
Use Bridge Mono mode to deliver the power of both channels to a single 8 or 4 load. Set
switch positions 6 and 7 to BRIDGE MONO ON
connect the loudspeaker as shown in
Bridge Mono Precautions
This mode puts a high demand on the amplifi er and speaker, Excessive clipping may cause
protective muting or speaker damage. Be sure the speaker has a suffi cient power rating.
