5.6.4.2.7 Audio Interface
MAGIC TH6 supports analogue as well as digital AES/EBU Audio interfaces.
If the digital Audio inputs are used, a Sample Rate Converter is available 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 AES/EBU/CLK adapter cable. The clock rate of the
connected clock must be 48-kHz.
–
Recovered
: The AES/EBU output clock is derived from the digital in-
put signal of the interface. This configuration is usually to be selected if
you use the digital input of the system. In this way a synchronous func-
tioning of the transmission chain is ensured
NOTE
If you are using MAGIC TH6 ISDN in the ISDN operating mode, the clock of
the AES/EBU output is 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.
