Bel Digital’s BM-A1-4SHD four channel audio monitor/de-embedder is already a firm favourite with broadcasters, now all of its features are available in a newly-launched larger 2U chassis, providing increased definition in metering and an increase in SPL.
With a reduction of both chassis depth (down to 200 mm) and overall weight, the new BM-A2-4SHD MKII is ideal for OB or Flyaway applications.
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 BM-A2-4SHD MKII 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 to 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.
Simple to set up and use, like the BM-A1-4SHD, all source selection and main monitoring setup is done from individual controls on the front panel, without any need for menu navigation.
The BM-A2-4SHD MKII’s audio performance is tuned for maximum clarity and delivers a higher SPL compared to the more compact BM-A1-4SHD monitor. Users also have full flexibility in assigning any channel to left, right or both speakers (or neither), and automatic level attenuation compensates for monitoring multiple channels. A ¼” 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 audio level at the rear panel analogue outputs may be configured to be either fixed or to follow the main volume control.
The 53-segment, tricolour LED bargraphs include user setup 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.
