INTRODUCTION
Accepts analogue, AES and SDI sources.
The Bel BM-AV3S is a 4 channel high quality 3U
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 7” TFT
video display.
Composite video output derived from SD
source.
Audio inputs provided are analogue (4), AES (2
pairs) and any audio group within the SDI bitsream.
High SPL audio reproduction.
The video content from the SDI inputs is available as
a composite output.
Large high resolution 7” 16:9 video monitor.
Ease of use via intuitive front panel
controls. Rotary controls are provided
instead of push buttons and menu
controls.
High resolution, tricolour level meters
with adjustable colour transition points &
peak-hold facility. Six standard scales &
ballistics, user assignable.
Designed to exceed current EMC
directives.
Fully RoHS compliant.
3 year warranty.
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.
