5.6.1.2.2 Audio Interface
MAGIC TH2 supports analogue as well as digital AES/EBU Audio interfaces.
If the digital interfaces are used, a separate Sample Rate Converter is available
for the input and the output so that external adjustments are not required if
there are different digital sources and drains.

Audio Interface
•The operating mode analogue or digital can be set separately for the Au-
dio Input and the Audio Output.
• If the output is set digital, additionally the configuration for the AES/EBU
Interface is displayed. Under Clock Source of digital output you can se-
lect 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
• If you operate the input or the output in an analogue mode, the corre-
sponding slide control for adjusting the nominal Audio level of the ON
AIR interface (ON AIR Nominal Level) is displayed. The nominal level
NOTICE
The AES/EBU input always works with recovered clock, therefore a config-
uration 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.
