A5.3 Audio interfaces
The system incorporates analogue and digital AES/EBU Audio interfaces.
For switching you can use display and keypad or the PC software.
A5.3.1 Analogue Audio interface
A5.3.2 Digital AES/EBU Audio interface
The MAGIC DC7/AC1 System incorporates two digital inputs/outputs which
are physically one AES/EBU interface. The input as well as the output has its
own sample rate converter providing that a digital source with 32, 44.1 or 48-
kHz can be connected directly. For external clocking (48-kHz only) the word
clock input or output may be used.
