Page 6: Introduction
Supports the following rear module connectors: RM71 for balanced analogue or AES audio operation and RM72 for unbalanced AES audio operation. • Compatible with Crystal Vision standard Indigo frames available in 2U, 1U and desk top box. • Passes all timecode, AFD and subtitling information. - Page 7 Crystal Vision Introduction TANDEM 320 functional block diagram (one video channel shown only) Block Diagram Description SDI video is cable-equalised, re-clocked and passed through a de-embedder block where up to 16 channels of audio are extracted. All input audio from both external (up to eight channels via the optional plug-in input piggyback) and de-embedded sources (16 channels) are passed to audio processing blocks where gain and delay adjustments are made after re-sampling.
