- “The Avenue 7600 audio embedder modules are easy to configure and that’s half the battle,” said Colin Smith, “We use the 7600 because it’s reasonably inexpensive and very flexible.” – Colin Smith, Senior Engineer at MPC
The 7660 module is an eight-channel audio embedder or disembedder for 1.5 high definition or 270 Mb/s standard definition signals. Four AES ports automatically configure as inputs or outputs depending on if the module is configured as mux or demux. Additionally, four channels of analog audio are supported.
Configurable Mux or Demux
When configured as a multiplexer, the 7660 has one serial digital video input and four AES audio inputs. These four AES streams are embedded into the video stream. AES inputs are sample rateconverted, allowing the use of asynchronous audio. The output of the module is a digital stream that contains the original video signal and four AES pairs, or eight channels.
When configured as a demultiplexer, audio signals present in the incoming video signal are extracted and delivered as standard AES digital audio streams.
The 7660 includes a full-featured, sixteen-channel audio mixer. The channel swap and shuffle capability allows you to completely rearrange and remix audio channels. It provides precise control over audio level, with up to 12 dB of gain to compensate for low level sources. Delay is adjustable up to one second.
In-Line Shuffler
Because the 7660 has simultaneous disembedding and embedding, it is an in-line processor for embedded audio. It can take embedded content, adjust levels and remap channels, and deliver it to the output as an embedded signal.
Dolby and AC-3
The 7660 can be fitted with Dolby E encoding and decoding options. The 7615 decoding option can be fed from either an AES input or an AES stream disembedded from the incoming SDI signal. The resulting discrete surround signals are then selectable as inputs to the sixteen channel mixer/shuffler.
The 7630 Dolby E encoder is fed from selected outputs of the sixteen channel mixer/shuffler. The resulting encoded bitstream can be output both on an AES output and embedded into the SDI output.
Additionally, the 7660 fully supports embedding and disembedding of encoded multi-channel bitstreams such as AC-3 and Dolby E.
LevelTrack™ AGC Option
The 9670 LevelTrack™ Audio Automatic Gain Control software key can be added as an option. This option provides control for keeping audio levels consistent in program material.
The 7660 can be configured locally or controlled and configured remotely with Avenue Touch Screens, Express Panels, or Avenue PC Software. Alarm generation, configurable user levels, module lockout, and customizable menus are just some of the tools included in the Avenue control system.
