4.7.2.3.2 Audio Interface
MAGIC DC7/AC1 supports analogue as well as optional digital AES/EBU-
Audio interfaces (order number 430230). If the digital interface is used, sepa-
rate Sample Rate Converters for input and output are available which super-
sedes external adjustments for different digital sources.
FIG. 44 CONFIGURATION OF THE AUDIO INTERFACES
Audio Interface
• The operating modes
analogue
or
digital
can be individually adjusted for
the
Audio Input
and
the Audio Output.
AES/EBU Interface
• If you select the option
digital
for the output, the configuration for the
AES/EBU Interface
is displayed. Under
Clock Source of digital output
the following settings are available:
–
Internal
: The AES/EBU output clock is adapted to the internal system
clock.
–
External
: The AES/EBU output clock is adapted to the external clock
which is supplied by the Audio 2/CLK IN interface. The clock fre-
quency of the supplied clock needs to be 48-kHz.
–
Recovered
: The AES/EBU output clock is recovered from the digital
input signal of the Audio 1/AES IN interface. This configuration should
be selected if you use the digital input of the system. In this way, a syn-
chronous working of the transmission chain is ensured.
NOTE
An AES/EBU input always works with recovered clock. Therefore, only a
configuration of the output is required.
For clock synchronisation with other systems, you can use the clock output
Audio 2/CLK OUT . The clock frequency of the output clock is 48-kHz.
