CONNECTIONS- Post Processor Outputs

Post Processor Outputs

Each processor has two post-processor outputs. They are labeled CH1 OUTPUT and CH2 OUTPUT. The audio present at these outputs is processed and the signal is the same as at the OUT1 and OUT2 blocks in the Signal Manager software. See Block Diagram, page 7, for details.

These are electronically balanced outputs with an impedance of 600 ohms with the shield terminal connected to the chassis. The outputs are suitable for daisy chaining the post processor signal on to other devices in the system. We recommend that no more than five balanced, pro-audio devices be daisy chained from any output.

The output connectors on the Processors are three pin terminal block connectors. They are sometimes called “Phoenix- or Euro-type” detachable terminal blocks.

The appendix provides part number information on these connectors.

Top Box Processor- Both CH1 and CH2 OUTPUTs are active for most applications. The signal output from each connector is same as the signal applied to the inputs of the top box amplifier.

Subwoofer Processor- Use CH1 OUTPUT only. CH1 OUTPUTs signal is the same signal applied to the input if the subwoofer amplifier. CH2 OUTPUT is not normally used.

The post processor outputs are recessed, located on the processor faceplates. Each processor has post processor outputs suitable for daisy chaining the processed audio on to other devices in your system using detachable terminal block connectors.

NOTES: The output levels of each processor are dependant on your settings in the Signal Manager

software when you configure the processor. If post processor outputs do not behave as expected,

connect your host PC to the processor and verify your configu- ration.

QSC recommends the use of balanced audio connections exclusively. We discourage the use of unbalanced connections as they are more prone to common-mode noise pickup and ground loop hum.

Subwoofer post-processor output is available for daisy chaining from the CH1 OUTPUT receptacle. The Subwoofer Processor CH2 OUTPUT is not normally used.
