8 Channel Balanced Analogue Audio Multiplexer

Description

8 Channel Balanced Analogue Audio Multiplexer The BC620T provides transmission of multiple channels of analogue line level audio over one optical fibre. All inputs are buffered then converted using full 24 bit A/D conversion then multiplexed onto a single optical data stream. The BC620T is particularly suited for multichannel audio transport and applications that require the audio to be carried independently to video or embedded audio signals. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. The BC620T is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC620T can be used with a BC630R allowing analogue inputs to feed AES outputs. The BC620T occupies a single slot in the BC100-3RU 19″ rack-mounting frame which can hold up to 15 single slot cards. Some BC Series processing cards have dual functionality allowing up to 30 channels of video to be transmitted or received from a single 3RU frame. Signal and card monitoring is achieved through SNMP monitoring in the BM101 network card. Alternatively GP-Output alarms can be triggered via the BM100 module. For stand alone applications the BC620T can be housed in an individual rugged enclosure.
