Introduction!
!!
The BM-AV2-16SHD is a 2U high-quality sixteen-channel video/audio monitor with an integral
Dolby® decoder. The unit accepts audio from any one of eight AES input pairs, eight
analogue inputs or one of two SDI inputs and produces eight pairs of AES outputs and eight
analogue outputs. The SDI inputs automatically detect SD or HD or 3G video and de-
multiplex all 16 audio channels. An active loop-through output is available for the SDI inputs.
The video source and menu system is displayed on the 4” video monitor.
The headphone output is taken before the limiters and mutes the speakers when used.
Sixteen high-resolution tri-colour bargraphs are provided with user-selectable ballistics and
colour break points. Up to sixteen PCM audio inputs or eight Dolby decoded audio inputs can
be selected individually or mixed and directed to each speaker.
Bargraph meters are arranged in four groups of four, the left hand groups handle inputs 1 to 8
and the right hand groups handle input 9 to 16. Stick-on graticule scales, which may be
applied to the spaces between the front-panel bargraphs, are supplied with the machine.
The sixteen audio channels are also provided at the rear of the unit as eight pairs of AES
signals on BNC connectors and four pairs of differential analogue signals. The analogue
outputs and line outputs can be at a fixed level or slaved to the front panel volume control.
The analogue and line outputs can be muted independently from the menu or under the
control of the front panel mute switch.
