Audio Routing & Processing
From C8000 System Bus
Select a 2ch or 8ch (multiplex) mode bus as an input for the DSP.
To C8000 System Bus
Decide between 2ch or 8ch (multiplex) mode and assign a bus to it.
Enable Bus Input
[ON / OFF]
Error Detection
The serial audio data from the frame bus can be monitored for
proper positioning of an Error-Flag. A bad Error-Flag is an
indication that there is disturbance upstream (input signal, input
module). The Error Detection can be turned off and on in
general. Each input in use will automatically be observed. You
will see the status on the left hand side:
“
Bus/Input Status
”. A grey soft LED shows that the detection is
disabled. While green is OK, red indicates an error condition.
The bus status may be presented to external monitoring systems
via SNMP. The frame controller summarizes such status
information and generates SNMP traps for the frame as an entity
or may activate GPOs (if a GPI/O module is installed).
The SNMP manager may afterwards poll the “modulesStatus”
for more detailed status information per input (see SNMP
documentation for details).
Enable Bus Driver
[ON/OFF]
You can disable the output drivers by un-checking the
Enable Bus Driver check box. The state of this check box also
depends on the setting of SW1 on the PCB.
If SW1 #1 is turned off, this checkbox will be off after a power
cycle. You can turn it on temporarily to check out your settings but
you must keep in mind that after the next power cycle it will be off
again unless you have turned SW1 #1 on.
This procedure is useful if you must insert a module into a frame
that is on air and other services must not be interrupted or
disturbed.
Important Note!
The remainder of this manual refers to the C8092-16 version
(16 channel and surround license enabled). Some settings are impossible for a four channel license,
but the parameters for the audio processor are the same.
