Bel Digital BM-A2-4SHD MkIIUpdating its BM-A1-4SHD audio monitor/de-embedder, Bel Digital has reduced of chassis depth and overall weight, making the MkII model ideal for OB and flyaway applications.

Housed in a 2U-high chassis that is 200mm deep, the BM-A2-4SHD MkII can de-embed any group of four channels of audio from one of two SDI sources (up to 3G SDI) and display the levels on the front panel meters, as well as providing stereo audio monitoring of any combination of the four channels. In addition to the auto-detecting SDI inputs, the unit has four balanced XLR analogue inputs and two AES3id BNCs. A re-clocked loop-through output is available for the selected SDI source, providing a convenient and cost-effective method of switching SDI feeds to an external monitor.

Channels 1-4 of the selected source are also routed to two AES3id outputs. Therefore providing format conversion and SDI de-embedding facilities. In addition, the stereo audio monitor mix is available as a separate balanced feed at a pair of XLRs. All source selection and main monitoring setup is done from individual controls on the front panel, without any need for menu navigation.

The unit offers flexibility of assignment of any channel to left, right or both speakers (or neither). Automatic level attenuation compensates for monitoring multiple channels. A quarter-inch jack headphone output socket is provided on the front panel, which mutes the loudspeakers when in use. If external monitoring on larger speakers is required, the rear panel analogue outputs may be configured to be fixed, or to follow the main level control.

The 53-segment, tricolour LED bargraphs include user set-up options to allow a choice of four scales and ballistics (including BBC or DIN PPM, VU and AES/EBU), as well as colour transition points and peak hold. The front panel LCD provides signal status information of the selected source (including video format of the selected SDI signal and AES lock) and volume level indication.
