The P DX 3214 B is a high quality digital AES audio de-multiplexer (audio de-embedder) designed primarily for broadcast and professional applications. The module accepts one digital video (SDI) input signal that can have up to four audio groups embedded. Two audio groups can be selected, de-multiplexed and output as AES3id signals on four 75 Ohm BNC connections. Four reclocked outputs of the input signal are also provided to cascade several modules if required. The module has a built in micro-controller with local controls, status and alarm indicators and well as internal flash ram for storing setups. Remote control and remote status monitoring is possible when used with the optional rack frame option and one of the available controller options or by using the Service Adapter and LYNX control software.
