Introduction - BEL BM-A1-16SHD User Manual

Introduction
The BM-A1-16SHD is a 1U high-quality sixteen-channel video/audio monitor with multiple I/O
as standard. The unit accepts audio from any one of four AES input pairs, eight analogue
inputs or one of two SDI inputs and produces four 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 headphone output is taken before the limiters and mutes the speakers when used. Eight
high-resolution tri-colour bargraphs are provided with user-selectable ballistics and colour
break points. Up to sixteen PCM audio inputs can be selected individually or mixed and
directed to each speaker.
Bargraph meters are arranged in two groups of eight, they can display 1 to 8 or 9 to 16 using
the select button under the status display. Stick-on graticule scales, which may be applied to
the spaces between the front-panel bargraphs, are supplied with the machine.
The eight audio channels are provided at the rear of the unit as four 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
two line outputs can be muted independently from the menu or under the control of the front
panel mute switch.
