11.1.3 AES Audio Outputs
•
Up to 120 balanced or unbalanced AES outputs (dependant on rear panel fitted)
•
Re-generates the AES clock from incoming data (nominal 48 kHz)
•
VU&C (Validity, User and Channel status) flags are regenerated to a default standard
on each channel when re-aligning audio. (See Table 120 on page 358 for default
standard details).
•
Pass asynchronous audio or Dolby E transparently at the original sample rate.
•
Asynchronous channels pass VU&C data transparently (parity is recalculated for each
output).
•
Up to 3 MADI outputs are also available on HD BNC connectors (with correct rear
panels, see section 11.12 for details)
•
Up to 64 channels of audio per MADI output
11.1.4 MADI Audio Outputs
To connect MADI audio outputs from a 4929 input module it must be used with either a 1295
BNC or 1296 Fiber rear panel.
•
Up to 12 MADI outputs, (one main and one duplicate output of each channel).
•
Up to 64 channels of audio per MADI output.
•
Maximum of 768 (12 x 64) audio channels per 4929 audio output module.
•
MADI streams are generated locked to the AES reference. All audio must be
synchronous for fully transparent operation. Re-generate VU&C data. (See Table 120
on page 358 for default standard details).
•
Asynchronous AES channels will be added to the MADI using drop/repeat techniques.
•
Asynchronous Dolby E will not pass error free through MADI outputs.
Note:
When fiber SFP modules are used the main and duplicate MADI outputs span two
separate SFP modules to guard against an SFP failure, see section 11.9 for details.
