QSC Audio CX168 Stereo Mode, Parallel Mode, How to use STEREO mode, How to use PARALLEL mode

APPENDIX: DESCRIPTION OF STEREO & PARALLEL OPERATING MODES

NOTE! In the following diagrams, channels 1 and 2 are shown as examples only. Any channel pair can be configured as shown here. The channels pairs on the CX168 are : Channels 1 and 2, Channels 3 and 4, Channels 5 and 6, and Channels 7 and 8. Therefore, in any example below, replace channel 1 and 2 with the channel pair numbers you are setting up.

Stereo Mode:

Each input signal is sent to its respective channel. Each channel has independent low-frequency (subaudio) filtering, clip limiting, gain control, and output connection.

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

How to use STEREO mode:

1- Set the MODE switches for stereo mode operation.

2- Connect the two input signals to CH1 and to CH2 (or signals may be provided from DataPort connection).

3- Connect the two speakers; one to channel 1’s output terminals, one to channel 2’s output terminals.

STEREO MODE OPERATION

NOTE: Ensure that the MODE SWITCHES are set to STEREO when feeding two separate signals to the two channels.

Parallel Mode:

The channel 1 and channel 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 low frequency filtering, clip limiting, and gain control still function independently. Each channel drives 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.

When to use PARALLEL input configuration: Use parallel mode when you need one signal to drive both channels; each channel having its own control (gain, clip limiter, low- frequency filter).

How to use PARALLEL mode:

1- Set the MODE switches for PARALLEL mode.

2- Connect the one input signal to either channel’s input connector. The unused input may be used for daisy chaining the signal to another device or channel pair.

3- Connect the two speakers: one to channel 1’s output terminals, one to channel 2’s output terminals.
