QSC Audio PL236A Manuel D’Utilisation

 

This switch selects between STEREO or PARALLEL

input configuration. The indicator LED’s above the switch confirm the switch setting.

PARALLEL: The CH 1 and CH 2 inputs are connected together, applying a
single input signal to both channels of the amplifier. A signal into any
input jack will drive both channels.  Each channel's subaudio filtering, clip
limiting, and gain control still function independently. Each channel feeds
its own speaker load.

You can patch the input signal on to additional amplifiers (“daisy-chain”)
by using any of the remaining input jacks. This feature eliminates the
need for “Y” cables.

The orange PARALLEL

 LED on the front panel clearly indicates when the

amplifier in configured for PARALLEL input.

When to use PARALLEL input configuration: Use PARALLEL when
you need one signal to drive both channels.

STEREO: Each input is sent to its respective channel.  Each channel has
independent subaudio filtering, clip limiting, gain control, and outputs. In
STEREO mode, a full-frequency signal may be presented to each channel.

When to use STEREO input configuration: Use STEREO for stereo
sources (L-R inputs) and any other situation that requires each channel to
be completely separate from the other.
