AES/EBU Digital Input
The AES input is used for digital signals with sample rates up to 96kS/s. The
data format is AES3.
Use with 110 ohm screened, twisted pair cable designed for digital audio or RF.
Do not use unscreened cables as they may pick up interference from other
appliances.
SPDIF Digital Inputs
The RCA and BNC inputs are used individually for digital signals with sample
rates up to 96kS/s. The data format is IEC60958, otherwise known as SPDIF.
RCA connectors are the type commonly found consumer equipment.
Use with 75 ohm co-axial cables designed for digital audio or RF use. Some
types of audio cable are not suitable and may cause crackling noises or other
malfunctions.
