If the AES/EBU module is equipped the digital audio data stream is available
on the OUTPUT LEFT connector. Via the PC the connector OUTPUT RIGHT
can be configured as clock input or output. The integrated Sampling Rate
Converter adapts the connected clock to the network clock. (Frequency
range: 24...64 kHz).
