BroadcastAsia will see the launch of the Bel Digital Audio BM-A2-E16SHD audio monitor/de-embedder.
The unit provides audio monitoring of 3G HD, and SD SDI video signals with loopthrough, and additionally offers Dolby E/Digital and Digital Plus decoding in addition to Integral Loudness metering compliant to ITU-R BS1770.
The 2U-high unit also provides visual monitoring of the de-embedded audio by 16 individual, high-quality, three colour, front panel mounted bar graphs, while audible monitoring is provided by two speakers also mounted on the front panel.
A comprehensive range of inputs and outputs are provided as standard. There are two SDI inputs alongside eight AES audio pairs and eight analogue inputs. The device provides auto-selection of 3G, HD and SD or SDI bitstreams and decodes as appropriate. Switching between inputs is accomplished by use of the simple, front mounted rotary controls.
All 16 audio channels present on the front panel bargraphs are also available as AES-3 outputs on the rear of the unit, enabling the monitor to de-embed all 16 audio channels from any SDI stream. In addition, a re-clocked SDI loopthrough and eight analogue outputs (with front panel level control) are provided.
Using the rotary control, users can monitor any channel and can create combinations and groups. The bar graph meters are switchable between all available channels and inputs. Each meter features adjustable colour transition points and a peak-hold facility. The ballistics are user assignable and seven standard scales are available to choose from, Nordic, BBC PPM, DIN PPM, VU, VU Ext, AES/EBU. Additionally Loudness metering, a subject of much discussion at present, is catered for by the unit to ITU-R BS1770.
The two monitor speakers on the front panel are switchable between any of the available channels and additional audible monitoring is provided via a headphone socket also on the front panel.
A Dolby decoder is included in the BM-A2-E16SHD as standard. When enabled it can decode Dolby E, Dolby Digital and Dolby Digital Plus material from any of the AES inputs, or from embedded audio data within the SDI bitstreams.
