4.3 Digital connections (AES/EBU and S/PDIF)

The AES/EBU interface whose name is derived from the Audio Engineering

Society and the European Broadcasting Union, is mainly used in professional

studio environments and broadcasting studios for the transmission of digital

signals, also over greater distances. The connection is made via balanced XLR

cables with a wave resistance of 110 ohms. Cables can be up to 100 m long.

The interface complies with the AES3 format, which allows for the two-channel

transmission of signals with a resolution of up to 24 bits. The signal has an auto-

clock and auto-synchronization feature (important when several digital devices

are used). An additional wordclock connection between DEQ1024 and connected

AES/EBU equipment is therefore not required. The sample rate is not xed and

can be chosen freely. Typical rates are 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz.

The AES/EBU interface is largely compatible with the popular S/PDIF interface.

Aconnection can be made using an adapter.
