BE 71 is a dual rate 8 channel analog audio embedder/disembedder for 1.5Gbps HD video signals or for 270Mbps standard definition signals. The analog audio ports automatically configure as inputs or outputs depending if the module is configured as mux or demux. When configured as a mux, the it has one serial digital video input and eight analog audio inputs. The audio streams are embedded into the video stream. The output of the module is a digital stream that contains the original video and audio signals. When configured as a demux, audio signals present in the incoming video signal are extracted and delivered as analog audio. It includes an eight channel audio mixer with channel swap and shuffle capability that allows to completely re-arrange and re-mix audio channels. It provides precise control over audio level, with up to 12dB of gain to compensate for low level sources. All audio processing is performed at full 24 bit resolution by a digital signal processor (DSP). Delay is adjustable up to one second.
