4 Channel AES Audio De-Multiplexer AES/EBU


4 Channel AES Audio De-Multiplexer AES/EBU The BC630R is a receiver for the conversion of an optical signal into 4 channels of AES/EBU digital audio. The incoming optical signal is fed to a trans-impedance and limiting amplifier before being electrically reclocked on the outputs. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. The BC630R card can be used with a BC620T unit allowing line level analogue inputs to feed digital audio AES outputs. Dual AES outputs are provided for each channel to provide local monitoring as well as a main transmission feed. The BC630R is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC630R 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 BC630R can be housed in an individual rugged enclosure.
