Product Description


The BM-AV2-E16SHD provides a pair of auto-detecting 3G/HD/SD SDI inputs and accepts 10 analogue audio inputs and 8 AES-3id pairs (also accepts SPDIF).

Integral to the BM-AV2-E16SHD is a high-quality 5" video display providing exceptional clarity and image definition. The selected audio inputs are displayed on 16 high-resolution multi-coloured LED bargraphs providing long term reliability. Selected audio channels are also provided as AES-3id and analogue outputs on the rear panel. Output levels can be fixed or controlled by the front panel volume control. An integral audio mix system enables any demuxed audio channel to be mixed on either, or both speakers, whilst maintaining a constant output level.

An SDI reclocked loop-through connector is provided enabling connection to downstream equipment.

Loudness measurement to ITU-R BS.1770-3/ EBU R128 standards is available and can be displayed in four different ways, with each showing different combinations of Loudness measures.

A Dolby decoder is included in the BM-AV2-E16SHD as standard. When enabled it can decode Dolby® E, Dolby® Digital and Dolby® Digital Plus material from any of the AES inputs, or from embedded audio data within the SDI bitstreams. Eight Dolby mix-down algorithms are available directly from a front panel rotary control. Comprehensive metadata reporting is also provided via the video display.

Two high quality and magnetically shielded speakers are mounted on the front panel, providing together with a ducted bass system provide high-SPL audio reproduction. Either speaker can monitor the sum of any combination of inputs.

A headphone socket is provided on the front panel.
