BEL AUDIO MONITORS - 2 channel, 4 channel

Bel in-rack, broadcast audio 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. Audio metering is via high-resolution tri-colour LED bargraphs with peak-hold and user-selectable scales, ballistics and colour transition points.

A 2x16 character display provides input status information. A configuration menu enables user-selection for the analogue line outputs to be fixed level, variable (following front panel volume/mute control) or permanently muted. Internal speakers are magnetically shielded.

BM-A1-2SHD MKII - 2 channels

This offers monitoring of two audio channels, selectable from two discrete SD/HD/3G-SDI streams, with loudspeakers and meters.

The front panel provides controls for the of audio input between SDI inputs 1 and 2, channel-pair selection, speaker volume/mute, balance and menu navigation and a display for relaying input status of the selected source. LEDs indicate left/right speaker assignment. There is also a balanced 6.35mm stereo headphone socket, which mutes the loudspeakers when used. Audio metering is via two, high-resolution, tri-colour, 26 segment LED bargraphs.

The rear panel provides two BNC connectors for SDI inputs and one re-clocked SDI loop-through output following the selected input. Two XLRs provide line level analogue audio outputs, which follow the sources selected to the left and right loudspeakers. The IEC power inlet with integral fuse has an adjacent power switch.

Video inputs: 2x SD/HD/3G-SDI to SMPTE 259M, 296M, 274M, 292M, 424M. Video loop outputs: 1x re-clocked SDI.
Analogue outputs: Electronically balanced, 50 ohms. Response: 20Hz to 20kHz +/- 1dB, Distortion and noise: -98dB below clipping.
Acoustic output: 90dB SPL peak, 0.6m.
Meter scales and ballistics: AES, DIN, VU, BBC.
Power source: 90-260V AC, 50/60Hz: 25W. Dimensions: 1U rack mounting, 200mm deep. Weight: 3.3kg.

Included accessories: User manual, IEC power cable (UK), adhesive meter-scale graticules.

BM-A2-4SHD MKII - 4 channels

This model offers monitoring, with loudspeakers and meters, four audio channels, selectable from two discrete, auto-sensing, SD/HD/3G-SDI streams, two AES3id digital audio inputs, or four analogue audio inputs.

In addition to audio metering, the front panel provides controls for audio source selection between SDI inputs 1 or 2, AES3id and analogue audio, SDI group selection, left and right speaker selection for channels 1-4, speaker volume/mute, balance and menu navigation. A display for relaying input status of the selected source. LEDs indicate left/right speaker assignment. There is also a 6.35mm stereo headphone socket, which mutes the loudspeakers when used.

The rear panel provides two BNC connectors for SDI inputs and one re-clocked SDI loop-through output following the selected input. Two BNC connectors are assigned for the AES3id inputs and four 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 3-pin XLRs provide line level analogue audio outputs, which follow the sources selected to the left and right loudspeakers. The IEC power inlet with integral fuse has an adjacent power switch.

Video inputs: 2x SD/HD/3G-SDI to SMPTE 259M, 296M, 274M, 292M, 424M. Video loop outputs: 2x re-clocked SDI.
Audio inputs: Analogue, nominal +4dBu, 25k ohms balanced; digital: AES3id, 110 ohms, balanced.
Audio outputs: Analogue, electronically balanced 50 ohms; Response: 20Hz to 20kHz +/- 1dB. Distortion and noise: -98dB below. clipping.
Acoustic output: 98dB SPL peak, 0.6m.
Meter scales and ballistics: AES, DIN, VU, BBC.
Power source: 90-260V AC, 50/60Hz, 25W. Dimensions: 2U rack mounting, 200mm deep. Weight: 5.2kg.

Included accessories: User manual, IEC power cable (UK), adhesive meter-scale graticules.

BM-A1-4SHD - 4 channel

This model has the same functionality as the BM-A2-4SHD MKII, but in a 1U chassis with 26 segment LED bargraph meters.
