VO5873 – DOLBY E DECODER & 2
X
SDI DE-EMBEDDER
The VO5873 can be fitted with up to 4
Dolby E decoder cards, each of which
can be assigned to decode a Dolby E
signal being input by any card or I/O
box on the Hydra2 network. This is a 3
slot-wide card.
In addition to the Dolby E decoders, this
card also offers the same functionality as
the VO5841 by providing 2 SDI inputs, the
audio from which can be de-embedded
and distributed across the Hydra2
network. As with the VO5841, this card
type can de-embed all 16 channels within
SD, HD or 3G SDI signals and provides
a “thru” output to pass on the SDI input
signal unchanged along with its original
audio content. SDI inputs and outputs are
via BNC connectors.
Although physically located on the same
card as SDI inputs, the decoders are in
fact fully assignable in their own right, able
to decode any Dolby E signal fed into any
input / I/O box (other than analog) on the
Hydra2 network, whether coming in as
a standard AES pair, or embedded into a
MADI or SDI stream.
Each decoder card is capable of decoding
one encoded signal. The decoder cards
themselves (Calrec stock code 491-102)
are optional extras and the quantity
required should be stated at order.
Metadata from the signals being decoded
is available via a 25 pin male D-type
connector.
LEDs A–D light up green to indicate if
decoder cards are fitted in the 4 available
slots.
Front panel LEDs for each input light
up green to indicate a valid SDI signal is
being received by each SDI input.

SPECIFICATION

and lights solid green once a connection
between the card and the Hydra2
interface has been established.
