From C8000 Bus

here you must assign the physical audio busses to the functional
module inputs.

Input Mux

here you select if the input audio signals are multiplexed in 2ch or 8ch
mode. If in 8ch mode only the upper bus assignment field will be
available.

Upmix Source

the radio buttons select between surround L/R and independent stereo
input as the feed for the upmix module

Bus Input 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,
other DSP module).
The Error Detection can be turned Off and On for each input from the
bus. You will see the status of the busses on the left hand side:
“Bus Status”. A grey “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 GPI/O module(s) are installed). The SNMP manager may
afterwards poll the “modulesStatus” for more detailed status
information per input (see SNMP documentation for details).

Cross Fader

this part cross fades the upmix output with the surround input, either
automatically if surround is detected or manually on demand.

Downmix

this circuit generates an automatic downmix in Lo/Ro format
by using the following parameters:

Ouput Gain

output level of the stereo downmix

Cmixlev

Center Mix Level

Smixlev

Surround Mix Level

To C8000 Bus

here you must assign the module outputs to the physical audio busses.

Output Mux

here you select if the output audio signals are multiplexed in 2ch or 8ch
mode. In 8ch mode the upper bus assignment field will be available
only.

Enable Bus Driver

turns on/off (tri state mode) all module bus drivers temporarily until
power cycle to set up the module without interference with other
modules already installed. See C8k system manual for details.
