5.7.2.2.7 Audio Interface
MAGIC TH2plus supports analogue as well as digital AES/EBU Audio inter-
faces. If the digital Audio inputs are used, a Sample Rate Converter is availa-
ble so that external adjustments are not required if there are different digital
sources and drains.

Mode
•The operating mode analogue or digital can be set separately for the Au-
dio Input and the Audio Output.
AES/EBU Interface
•If the digital output is selected, the configuration for the AES/EBU Inter-
face is displayed. Under Clock Source of digital output you can select
the following options:
– Internal: The AES/EBU output clock is derived from the internal sys-
tem clock.
– External: The AES/EBU output clock is derived by the external clock
connected via the interface Audio 2/CLK IN. The clock rate of the con-
nected clock must be 48-kHz.
– Recovered: The AES/EBU output clock is derived from the digital in-
put signal of the interface Audio 1/AES IN. This configuration is usually
to be selected if you use the digital input of the system. In this way a
synchronous functioning of the transmission chain is ensured
NOTE
In the ISDN Mode, the clock of the AES/EBU output is always derived from
the ISDN clock. Therefore, if the ISDN Mode is selected, this settings will not
be displayed.
The AES/EBU input always works with recovered clock, therefore only a
configuration of the output is required.
For clock synchronisation to other systems you can use the Audio output Au-
dio 2/CLK OUT. The clock rate of the output clock is 48-kHz.
