Audio Interfaces on the optional AES/EBU/Analogue Module
There are two digital inputs/outputs or two additional analogue inputs/out-
puts available on the AES/EBU/Analogue Module. The configuration is
made using the Windows PC software.
NOTE
The digital and analogue audio outputs on the modules are connected in par-
allel. Consequently the signal can be used on both interfaces simultaneously.
A2.7.1
AES/EBU Audio Interface
The AES/EBU digital Audio Interface is implemented as a 9-pole SUB-D
socket. Therefore the ISDN Telephone Hybrid has two digital inputs/outputs
on one physical AES/EBU interface. Optionally an XLR adapter can be sup-
plied. The input as well as the output have their own sample rate converters.
With these, a digital source of 32, 44.1 or 48-kHz can be connected directly. For
synchronisation to an external clock (only 48-kHz) the word clock input or
output may be used.This is implemented on the adapter as a BNC socket.
