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

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.
