HD-DIP2: Dual digital audio input sub-module
Audio input
2 x 24 bit stereo pairs. AES3 110 Ohm or HiZ (balanced) D Type, or
AES3-id (unbalanced) 75 Ohm BNC. Set by on-board links
Synchronisation
Synchronous audio to video 48kHz
HD-DIP2-RS: Dual digital audio input re-sampler sub-module
Audio input
2 x 24 bit stereo pairs. AES3 110 Ohm or HiZ (balanced) D Type, or
AES3-id (unbalanced) 75 Ohm BNC. Set by on-board links.
Synchronisation
Asynchronous audio to video 30kHz to 108kHz sample rates
Total harmonic distortion
0.0002% THD+N rms.
HD-DOP2-110 and HD-DOP2-75: Dual digital audio output sub-modules
Audio output
2 x 24 bit AES/EBU stereo pairs. HD-DOP2-110, 110 Ohm or HD-DOP2-
75 (unbalanced) 75 Ohm BNC. Factory configuration only
Each of the two AES signal outputs has a second buffered output, which
may be available dependant on the RM module fitted.
