The MA64 is a 64-channel MADI to AES interface with both coaxial and optical MADI inputs. 32 two-channel audio outputs are available in both balanced AES3 and unbalanced AES3-id formats, with/without SRC. It is transparent to both Dolby E and Dolby Digital. Comprehensive sync options and dual power supplies are standard. Rack-mounting (1U).

The BM-A2-64MADI provides all the functionality of the MA64, plus comprehensive audio monitoring and analysis of the MADI data. The SAM64 SDI-audio interface can de-embed 64 audio channels from 4 SDI video streams (SD/HD/3G) and make them available as both a MADI output and 32 AES3-id outputs.
The MA64 converts the 64 (or 56) audio channels present in the incoming MADI bitstream to both 32 AES3 balanced pairs and 32 AES3-id unbalanced pairs. Sample Rate Conversion may be selected for all channels if required. Both 75 ohm coaxial and SC multi-mode optical MADI inputs (AES 10d-2008 compliant) are provided; a single-mode option is available for the optical input. Both formats incorporate loop-through outputs.
The balanced audio outputs are on the front panel for convenience of patching to console I/O racks, in the form of four 25-pin Dsub connectors wired to the familiar “Tascam” standard. Unbalanced outputs are on the rear panel, on a 37-pin hi-density Dsub connector. 1U break-out panels for both formats are available as accessories: the BOB/O-32 makes the AES3 balanced outputs available on 16 XLR connectors (two required), while the ASBO makes the AES3-id unbalanced outputs available on 32 BNC sockets.
The synchronisation source may be selected from word clock, AES3, black-and-burst video or the MADI input. Sync outputs are available in word clock and AES3 formats. An Ethernet interface is included to facilitate firmware updates.
Broadcast-standard reliability is achieved with dual power supplies (with separate IEC inlets) for full redundancy, careful choice of components and extensive test and QC procedures.
