MASTER SELECT
if the module is turned into Master mode by SW1, you may select here
one of the four AES inputs as the actual MASTER input. In this case
the clock reference of that input will be used to synchronize the whole
C8932 or an island of the C8934 frame.
Important note! For a C8932 frame the C8189 must be placed into one of the slots marked red and no
other sync source (e.g. C8830) must be installed.
Sample rate Converter
it is possible to turn on a SRC for that AES input.
to C8000 Bus here you assign the audio signals from the AES inputs to c8k busses
8ch Mux sends all 4 signal pairs on one bus line
Ch 1/2 … Ch 7/8 sends a pair of input signals to one bus line
Enable Bus Drivers turns on all module bus drivers (from tri state mode to active).
from C8000 Bus here you assign the signals from the c8k bus to the AES outputs
8ch Mux receives 8 channels from one bus line. The assignment of pairs to the
AES outputs must be done by the respective check boxes
Ch 1/2… Ch 7/8 receives a pair of signals from the c8k bus
Transparent Status Bits
if not checked the Channel Status of the AES transmitter will be set to:
Format : Professional
Audio Mode : Audio
Emphasis : None
Freq. Mode : Locked
Sample Freq. : 48kHz
Channel Mode : Not Indicated
User Bits : None
Auxiliary Bits : 24Bit
Audio Word Length : Not indicated
AES Input Error Detection the status of the AES inputs can be monitored for AES signal present
and for 3 detailed error types:
Lock AES receiver lock status
Validity AES3 validity bit detected
Parity AES parity (data errors detection)
You can mask each AES input for error detection:
grey - error detection disabled
green - no error detected / PCM audio
yellow - no error detected / non audio (Dolby E, D)
red - indicates an error condition.
Bus 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 Bus Status on the left hand
side as a soft LED.
grey - error detection is disabled
green - no error detected / PCM
yellow - no error detected / non audio (Dolby E, D)
red - indicates an error condition.
The bus status may also be presented to external monitoring systems
via SNMP.
