Working with 3Gb/s, HD and SD sources, TANDEM 310 can embed and de-embed a mixture of up to four groups of AES and two groups of analogue audio at the same time, and includes full audio routing, audio and video processing, integrated fibre connectivity, flexible delay compensation and Dolby E decoding. TANDEM 310 is Crystal Vision's first 3Gb/s-capable embedder for analogue audio (as well as digital) making it ideal for use with microphones in the studio, and the first Crystal Vision product to include Dolby decoding. TANDEM 310 embeds and de-embeds external audio by fitting up to two audio piggybacks to the main board, with three different piggybacks available. For analogue audio the HD-AIP2 is used for embedding two stereo pairs or four mono channels and the HD-AOP2 for de-embedding two stereo pairs or four mono channels. For digital audio the DIOP4 piggyback will embed or de-embed four stereo pairs, with four bi-directional AES ports available on each piggyback and the engineer able to select whether to embed or de-embed each channel independently. By fitting two of these piggybacks TANDEM 310 can be configured as a two group analogue audio embedder/de-embedder or a four group AES embedder/de-embedder. Alternatively analogue and digital piggybacks can be mixed to create a hybrid system – ideal for those using analogue microphones with digital audio mixers in the studio. TANDEM 310 is Crystal Vision's first product to be fitted with the DBE-D top board to create a combined embedder, de-embedder and Dolby decoder, which is a more convenient and space-saving way to decode Dolby E signals that need to be de-embedded or re-embedded than using separate products for the task. The DBE-D Dolby decoder connects directly to the main TANDEM 310 module through an expansion connector, hooking into the onboard audio router, and is perfect for those applications where the audio within the Dolby E stream needs to be processed in some way, or where the Dolby E needs to be decoded before transmission. The DBE-D allows a Dolby E signal to be decoded and then either output as analogue or AES audio (using the appropriate output piggybacks) or re-embedded into the output video, with the Dolby signal coming either from the embedded video input or from an external audio stream which is input via a DIOP4 piggyback. TANDEM 310 will be shipping in January.www.crystalvision.tv
