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 reclocked 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.

Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters
to align them with the output timing. Output AES is always precisely locked in time with the output
video. Analog audio is differential input and sampled at 48 kHz with 0 dbFS digital equivalent to +24
dBu analog. Dolby decoding is available from embedded audio or external AES, with the purchase of
the Dolby decoding option.
The product also provides full color processing control of the output video, with separate controls for
Gain, Lift, Saturation and Color Phase.
All card configuration is done with a simple front panel menu. There is a four character text display to
view and control parameters, and a toggle switch and two buttons to navigate the menu.
The input and outputs of the 9323 are the following:
Input:
One dual-rate HD/SD-SDI video input
4 dedicated AES input connections (AES input 5-6)
8 differential analog audio inputs
Switchable Input/Outputs:
4 AES connections, switchable between input and output (AES input/output 1-4)
Outputs:
Two dual-rate HD/SD-SDI video outputs
Two dual-rate HD/SD-SDI re-clocked copies of input
8 dedicated AES output connections. (AES output 1-8)
Software Version
This manual is written for software release number 2.0.
To view the current software release number of your 9323 check the information submenu on the
front edge controls or the card info menu in Dashboard.
To upgrade your 9323 software, go to the download page at www.cobaltdigital.com to download
the latest release, and upload the file through Dashboard™ (see Dashboard™ user manual, 3-5).
Functional Block Diagram
The 9323 has a very flexible signal flow path and feature set that combines several products into one
compact package. This section describes the basic operation of your 9323 product.

The 9323 is best thought of as a large audio router, with a variety of input format and output formats
available. Router inputs are de-embedded audio, discrete AES audio, differential analog audio, and
(optionally) Dolby Decoded audio. Router outputs are embedded audio, and discrete AES audio
Each router output provides a gain and polarity control, and each router output can be sourced from
any input channel. This router feature gives your 9323 a great deal of flexibility.
There is also a video proc module to allow any necessary corrections to the inbound video signal. It has
separate controls for Luma gain (Y channel), Saturation (C channel gain), Lift (Y channel offset), and
Phase adjustment (C channel).
All card features are controlled through the card edge menu interface. There is a 4 character display, a
toggle switch, and two buttons to allow for intuitive control of all device features.
The card has persistent storage of all settings. There is a menu option to trigger a save or load of stored
settings, or to restore the factory default configuration.
Supported Audio and Video Formats
Input and Output Video
The 9323 supports the complete range of modern SMPTE standard SD and HD video formats.

Embedded Audio
The 9323 supports all four groups (16 channels) of embedded audio at full 24 bit resolution in both SD
(with extended data packets) and HD.
Analog Audio
The 9323 supports 8 channels differential analog audio. The analog audio is encoded in such a way as
to make +24 dBu (analog) equivalent to 0 dBFS (digital). Analog audio conversion can be disabled to
reduce power consumption.
Discrete AES Audio Input
The 9323 can accept 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The
AES must have a nominal rate of approximately 48 kHz. Sample rate conversion is employed to
account for minor clock rate differences in the AES stream and the input video stream. However, the
card does not support AES input at 32 kHz, 44.1 kHz, 96 kHz or 192 kHz rates.
Discrete AES Audio Output
The 9323 can emit 16 channels (8 pairs) of discrete AES audio on 75 ohm BNC connections. The AES
clock rate will be precisely locked to the output video rate.
Dolby E Decoding
Dolby E decoding is available as an optional feature. It allows decoding from a discrete AES source, or
an embedded audio pair. The decoder will return up to 8 decoded channels (according to the Dolby E
sub-format) plus a 2 channel down mix for monitoring. All 10 of these channels are available as inputs
to the audio router.
AES Audio Input Advanced Features
AES Sample Rate Converter Bypass
The card’s AES inputs have built in sample rate converters that are enabled by default. This allows the
card to interface with asynchronous AES sources (sources who’s AES timing does not match the video
reference timing.). They can be bypassed with a control in Dashboard or the front panel. This is a
necessity when trying to embed non-PCM AES audio such a Dolby E or Dolby Digital audio streams.
This control is off by default.
Zero-Delay Audio Embedding
Sometimes it is desirable to embed AES with minimum latency. For example, if you want to embed
Dolby E audio into video with no latency, and delay the video by one frame to account for Dolby E
encoding delay. By turning this control on for a given AES pair, the pair will be directly embedded into
it’s corresponding group, bypassing the normal frame sync audio delay. (AES Pair 1 into Embedded
Group 1, ch1 & ch2, AES pair 2 into Embedded Group 2, ch3 & ch4). This control overrides the
standard audio routing system: if AES Pair 1 is selected, then the controls to route into Embedded
group 1, ch1 & ch2 don’t apply. There is no gain or polarity control available when this option is
selected. This control is off by default
