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.
