Sennheiser Spectera MADI Card (BNC)

The Spectera MADI Card (BNC) is an optional expansion card that adds coaxial MADI to the Spectera Base Station. It carries the AES10 MADI standard over a 75 Ohm BNC connection, giving the base station a direct tie into MADI-based consoles, routers, and stageboxes alongside its Dante interface.

The card handles 32 inputs and 32 outputs at either 48 kHz or 96 kHz in 16 or 24 bit. The base station has two expansion slots, so a pair of these cards can be fitted for redundant MADI paths. This is the BNC coaxial version; a multimode optical (OM) card covers fiber runs.
