1 AES/EBU-IN
A digital AES/EBU input (AES3) is provided in addition to
internal analog inputs. The digital input signal has to be
connected to the AES/EBU IN connector. The AES/EBU
input is a balanced transformer-isolated input. A sampling
rate converter translates the input signal to match the
internal sampling rate. However, the possibility to
synchronize the RCM-26 to an external sampling rate exists
as well. For further details, please refer to the IRIS-Net™
help files. Illustration 4.4 shows the pin-assignment of the
input socket.
2 AES/EBU-OUT
The AES/EBU OUT connector allows looping-through the
digital audio signal to other RCM-26 modules. The digital
input signal gets internally buffered and preprocessed (level
matching / slew rate) before it is output via the OUT-
connector. This allows fairly simple wiring between
modules, without the need for AES/EBU distribution amps
as they are usually used.
The RCM-26 has a bypass-relay, which, in case of damage
(e.g. power outage), connects the AES/EBU IN signal
through to AES/EBU OUT. This ensures trouble-free
operation of downstream remote amps.
