INTRODUCTION
The Bel BM-AV2SL is a 4 channel high quality 2U
video/audio monitor with alarm facilities. It accepts
video sources from 2 x SD SDI and 1 composite
(with automatic PAL/NTSC selection) inputs. The
resulting image is displayed on a high quality 4” TFT
video display.
Audio inputs provided are analogue (4), AES (2
pairs) and any audio group within the SDI bitsream.
Outputs of the selected 4 audio signals are available
in analogue and AES form. Active or re-clocked
outputs of the SDI, video and AES inputs are
provided, together with the video recovered from
the SDI input in composite form.
Input levels are displayed on 4 high-resolution,
tricolour bargraph meters with user-adjustable
colour transition points and peak hold facility. Six
standard scales and ballistics are user-selectable.
Analogue input and output levels can be independently
adjusted. The audio source selected for monitoring
is available as a line output and at a headphone
front panel socket.
High quality magnetically screened speakers are used
to provide high-SPL audio reproduction. A limiter
circuit is included to prevent speaker damage.
The monitor also provides alarm facilities for audio
over/under level, sustained anti-phase and video
loss. An RS232 port provides remote control of all
switch and alarm functions.
