The H8000FW offers 4 channels AES-EBU via XLRs connectors + 8 channels via DB-25 connector and an optional cable for it. If your audio interface doesn't support (multi-channel) AES-EBU, there is no way around. You can only buy professional one that supports 8 channels. Obviously the configuration of sending/returning 8 channels at 96KHz depends on such hardware and the DAW used with it. The H8000FW can operate via 8 AES-EBU I/O at 96 K.
