The 4×2-channel AES/EBU input board handles AES/EBU and S/PDIF data and is available with either XLR and RCA coaxial, TOSLINK optical or BNC ports. In addition, versions featuring RJ45 and 15-pole D-Sub ports receiving all channels over a single port can be supplied for use in fixed installations. The four stereo channels can also be configured as eight mono channels and be routed freely and independently on the NEXUS system.
