7600 is a dual rate eight-channel audio embedder or disembedder for 1.5Gbps HD video signals or for 270Mbps SD signals. Four AES ports automatically configure as inputs or outputs depending on if the module is configured as mux or demux. When configured as a mux, the 7600 has one serial digital video input and four AES audio inputs. These four AES streams are embedded into the HD or SD video stream. AES inputs are sample rate converted, allowing the use of asynchronous audio. The output of the module is an HD or SD digital stream that contains the original video signal and four AES pairs. When configured as a de-mux, audio signals present in the incoming video signal are extracted and delivered as standard AES digital audio streams. It includes a full-featured, eight channel audio mixer. The channel swap and shuffle capability allows to completely re-arrange and re-mix audio channels. It provides precise control over audio level, with up to 12 dB of gain to compensate for low level sources. All audio processing is performed at full 24 bit resolution by a digital signal processor (DSP).
