Bel in-rack, broadcast monitors are designed for use in master control rooms, transmission suites, OB vehicles or as part of fly-away systems, to provide accurate assessment of signal quality. This model offers monitoring of both video on a display and audio with loudspeakers and meters.

Audio metering is via high-resolution, tri-colour, LED bargraphs with peak-hold and user-selectable scales, ballistics and colour transition points. Meter scales and ballistics include AES, DIN, VU, and BBC. Internal speakers are magnetically shielded.


This unit has a high-definition, 5 inch, 800 pixels x 480 lines, TFT, colour, video monitor It accepts two auto-sensing SD/HD/3G-SDI video inputs, two unbalanced AES3id input pairs, and four balanced 3-pin female XLR analogue audio inputs. Compatibility includes SMPTE 259M, 296M, 274M, 292M, and 424M. In addition to the four 53-segment, tri-colour, audio meters and associated selection switches, the front panel provides controls for selection of audio source, volume/mute control, balance control and a menu navigation encoder. LEDs indicate left/right speaker indication. An on-screen display provides input status plus configuration menus. There is also a 6.35mm stereo headphone jack socket which mutes the loudspeakers when used.

The rear panel provides two 75 ohm BNC connectors for SDI inputs and one re-clocked, SDI, loop-through output following the selected input. Two 110 ohm, balanced, BNC connectors are assigned to the AES3id inputs. Four balanced, 25k ohms, 3-pin, XLR connectors are provided for analogue audio inputs. Two BNC connectors provide AES3id outputs, which follow the four audio channels active on the front panel. Two electronically balanced, 50 ohm, 3-pin, XLR sockets provide line-level, analogue, audio outputs with a frequency response of 20Hz to 20kHz (+/-1dB), which follow the sources selected to the left and right loudspeakers. The IEC power inlet with integral fuse has an adjacent power switch.
