Calrec Hydra2 VO5841 SDI

Calrec Hydra2 VO5841

The VO5841 provides 2 SDI inputs, the audio from which can be deembedded and distributed across the Hydra2 network. This is a 1 slot wide module with SDI interfacing via BNC connectors.

All 16 channels of audio can be deembedded from SD, HD or 3G SDI signals.

For each SDI input, there is an SDI 'thru' connector which passes on the incoming SDI signal, unchanged, with its original audio channels included.

Front panel LEDs for each input light up green to indicate a valid SDI signal is being received.

The standard modular I/O status LED flashes green once the card has booted and lights solid green once a connection between the card and the Hydra2 interface has been established.

Maximum channel count

As Hydra2 links are limited to 512channels of audio in each direction, each I/O box can be populated with cards that provide a maximum of 512 input channels, and 512 output channels. When counting inputs and outputs GPIO ports must also be included.

This limitation becomes a factor when a large number of SDI cards are fitted in the same modular I/O box. Channels are counted across the card slots from left to right. If, for example, SDI de-embedder (audio input) cards are fitted in the first 16 card slots, the input channel count will be at its maximum (16 channels of audio per SDI output x 2 SDI outputs per card x 16 cards = 512 channels).

Any input cards fitted in the remaining 4 slots will not pass audio or GPIO signals, irrespective of whether audio is being used from any or all of the SDI inputs.

The remaining card slots could however be fitted with output cards as inputs and outputs have separate channel count quota's.

Note, the channel count totals mono audio channels and therefore each SDI stream has a channel count of 16 and each digital AES port has a channel count of 2.
