MADI-MON

MADI-MON: MADI Audio and Status Monitor


The MADI-MON was designed from the outset for the broadcast and production environment. The 2U in-rack monitor enables auditioning of embedded channels without the need to connect to external routers or audio consoles. In addition, MADI-MON is the first device to provide studio engineers with the tools necessary to interrogate the MADI stream in order to view the status of embedded channels. As a result it should be the perfect device for the maintenance of, or commissioning of MADI-based systems.

Providing bargraph metering for up to 32 stereo pairs (64 channels), MADI-MON provides ‘at-a-glance’ assurance of signal presence across the complete MADI stream. Selection of the stereo-pair to be audibly monitored is simple and intuitive, and once selected is also metered on a dedicated high-resolution stereo bargraph meter.

MADI-MON also makes 32 pairs of balanced AES/EBU and unbalanced AES3-id available simultaneously for interconnection to broadcast routers, audio consoles or any other AES equipped devices.

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

As the MADI-MON can be used ‘in-line’, it provides both coaxial and optical MADI loop-through outputs. As with all other 4HM products, it demonstrates its true broadcast credentials by the inclusion as standard of internal redundant power supplies.
