Bel BM-A2-64MADI

Designed for broadcast, live sound and production applications, the Bel BM-A2-64MADI audio monitor unit (AMU) enables auditioning of embedded MADI channels without the need to connect to external routers or audio consoles. In addition, the BM-A2-64MADI is the first device to provide engineers with the diagnostic tools necessary to interrogate MADI streams in order to view the status of embedded channels. As a result it is also the perfect monitor for the maintenance of, or commissioning of MADI-based audio systems.

The BM-A2-64MADI is fully compatible with 96 kHz, 88.2 kHz, 48 kHz and 44.1 kHz sample rates. In addition to this, the monitor is compatible with both the legacy SMUX and High Speed MADI protocols.

Providing bargraph metering for all 32 stereo pairs (64 channels), the BM-A2-64MADI provides ‘at-a-glance’ assurance of signal presence across the complete MADI stream. Selection of the stereo-pair to be audibly monitored is very intuitive, and once selected, both channels are also metered on a pair of dedicated high-resolution bargraph meters. For live sound or studio applications, the BM-A2-64MADI can easily be configured to monitor individual channels rather than channel pairs.

The status of the MADI stream can be interrogated using the unique MADI Data display. From here it is possible to view useful information such MADI frame data and AES status/user bits of each embedded stereo-pair. General configuration menus are also available, such as selection of sync source (including wordclock, video, AES and MADI) and sample rate converter.

In addition, the BM-A2-64MADI simultaneously makes 32 pairs of balanced AES/EBU and unbalanced AES3-id available for interconnection to routers, audio consoles or any other AES equipped devices.

As the BM-A2-64MADI can be used ‘in-line’, it provides a MADI loop-through output in both optical and coaxial formats.

Up to eight or sixteen MADI streams can be monitored on a single

BM-A2-64MADI when used in conjunction with one or two MADI-SWITCH 8x1 MADI Source Selectors.
