4 Channel AES Audio Multiplexer AES/EBU


4 Channel AES Audio Multiplexer AES/EBU The BC630T is a transmitter for the transport of digital audio over fibre optic cable with the ability to carry 4 channels of AES/EBU audio. The incoming signal is auto-sensed and then equalised prior to multiplexing, conversion and transmission down a single optical fibre. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. The BC630T card can be used with a BC620R unit allowing AES inputs to feed line level analogue outputs. The BC630T is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC630T 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 BM102 network card. For stand alone applications the BC630T can be housed in an individual rugged enclosure.
