A Word of Thanks
Congratulations on choosing the openGear 9323 HD/SD Audio Embedder/De-embedder. The 9323
is part of a full line of modular conversion gear for broadcast TV environments. The Cobalt Digital
openGear line includes video decoders and encoders, audio embedders and de-embedders, distribution
amplifiers, format converters, and much more. Cobalt openGear modular conversion gear will meet
your signal conversion needs now and well into the future.
Should you have questions pertaining to the installation or operation of your 9323, please contact us at
the numbers listed on the back cover of this manual. We are happy to help with any questions regarding
this or any other openGear card.
Overview
The 9323 is a high quality audio embedder/de-embedder capable of embedding audio signals into HD
or SD SDI signals, and de-embedding audio data from those signals. It also gives as outputs, two re-
clocked copies of the input.
The 9323 can best be thought of as an audio router on a card. On the input side of the router are the up
to 16 channels of embedded AES in the input video, the up to16 channels (8 pairs) of discrete AES
input, up to 8 channels of differential analog audio input, and up to 10 channels (8 signals plus
mixdown) of decoded Dolby signals (with Dolby Decoder option). On the output side are the up to 16
channels of embedded AES audio, and the up to 16 channels (8 pairs) of discrete AES output. The
router acts as a full audio cross point: each of the 32 output channels (16 embedded AES, 16 discrete
AES) can receive signal from any one of the 52 (16 embedded AES, 16 discrete AES, 8 Analog, 10
Dolby decoded) input channels. Each output also allows gain adjustment and optional polarity
inversion.
