Sirius 800 Series User Manual 4929 Sirius 800 Audio AES/MADI Output with Audio Delay Output Modules and Rear Panels 11.1
Iss 5 Rev 7 Page 176 © 2017 SAM
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.
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.
