4929 and 4925- AES/MADI Output Module
Audio Delay - 4929 only
(free License with each module)
Audio Delay
Per audio output channel in steps of 0.25 ms
•
MADI
- in a range of 0 to 2 Seconds @ 48 kHz
•
AES
- in a range of 0 to 2 Seconds @ 48 kHz
Audio Processing - 4929 only
(optional Licensed features - see section 3.6)
Sample Rate Conversion (SRC) License, SAM Order Code: S8A-SRC (1 per module,
768 mono channels on MADI/240 mono AES channels)
Sample Rate
Conversion (SRC)
•
Supported input sample rates from the audio crosspoint: 32
kHz, 44.1 kHz or 48 kHz
•
MADI
- Supports conversion to: 48 kHz
•
AES
- Supports conversion to: 32 kHz, 44.1 kHz, 48 kHz
•
Dolby
- signals must be routed as a synchronous AES pair.
The Dolby signal will automatically bypass the SRC even if
the pair is selected for sample rate conversion. Any near rate
reference locking is achieved by dropping or repeating Null
samples in the guard band.
Audio Processing - 4929 and 4925

Silence or -72 to +30 dB in 0.1 dB steps
Phase Invert
Available per mono or stereo signal. NORMAL/INVERT control
(on/off)
Stereo Mode
