An optional output board that handles 34 AES/EBU audio (balanced) signals. It supports 48-kHz sampling frequency synchronized with the reference word sync signal of the Routing Switcher IXS-6700 and IXS-6600. As the IXS-6700 can accept up to eight IKS-A6061 boards, the number of inputs can be expanded from 34 to 272, in units of 34. As the IXS-6600 can accept up to four IKS-A6061 boards, the number of inputs can be expanded from 34 to 136, in units of 34
