Fig. 4.4: 1/4" TRS connector for insert send/return applications 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 autoclock 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 fixed 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. 5.
