The pushbuttons on the front panel select which of the four digital audio inputs is routed to the output. All inputs and outputs use 3-pin XLR connectors, as per the AES standard.
Transformer coupled inputs and outputs improve common mode rejection over longer transmission line lengths. A phase locked loop receiver is used for clock recovery and regeneration, allowing a reclocked data stream to be generated at the output, along with a front panel Lock status indicator.
Output switch timing is synchronized with the channel A preamble of the incoming AES/EBU digital audio signal.
