Digital AES/EBU Audio interface
The RTS SIP-ISDN System incorporates two digital inputs/outputs which are physically
one AES/EBU interface. The input as well as the output has its own sample rate con-
verter providing that a digital source with 32, 44.1 or 48-kHz can be connected directly.
For external clocking (48-kHz only) the word clock input or output may be used.
