RB-VHDDD8 Audio Connections
The RB-VHDDD8 has 6 digital audio output connections available on the rear panel. The
digital audio output connections are transformer-coupled balanced line interfaces and can
be configured to be either 75ohm (AES 3ID) or 110ohm (AES 3) output impedance through
either a BNC or via the D-type connector. These output connections are paralleled, allowing
one type to be used per output.
The digital outputs are always output at 48kHz and will be synchronous to the video signal.
No sample rate conversion is applied to the digital outputs.
Dolby Output
The output labeled as
DO
is a dedicated Dolby output. This output is an exact copy of
the data that is selected to be sent to the Decoder. This provides an output that can be
connected to other decoder or monitor equipment in the broadcast chain without the need
of extra de-embedding equipment.
Digital Audio Outputs
The outputs labeled as
CH1/2, CH3/4, CH5/6, CH7/8
and
AUX
are configurable digital audio
outputs that can be sourced from either the decoder outputs or the de-embedder outputs
on a per channel basis. By default they are sourced from the Dolby Decoder outputs, and
the labels relate to this. The
AUX
channels are the down-mix output from the Decoder.

Remote I/O
There are 8 remote inputs and outputs available on the unit, through a 25 way D-type
female connection on the rear panel. The remote outputs are provided as open collector
outputs.
The outputs are fully configurable through the front panel menu control or from the remote
control software. They can be set to active high/low, latched/momentary and to a number
of triggering events. See the REMOTE OUTPUTS menu selection for more information.
