BB600R 12 Channel Balanced Analogue Audio De-Multiplexer Audiopdf

bb600r

The BB600R is a 1RU sub rack frame device which works in conjunction with the BB600T. The output optical signal from the BB600T is received by the BB600R. This optical signal is converted to an electrical serial data stream which is then de-multiplexed into twelve digital audio signals. The resultant analogue audio outputs are presented at the front of the unit on twelve XLR connectors.

The XLR connectors provide provide simple and easy connectivity, particularly for outside broadcast or live event applications. An unbalanced RCA phono version is also available.
All Bluebell products are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. Careful attention has been paid to reduce thermal runaway, eliminating the need for forced air cooling as fan failure and overheating is the most common cause of failure in modern electronic systems.

The BB600R is available in multimode and singlemode variants to suit any fibre application.
The receiver modules used in the BB600R are wide band receivers which work with either Multimode or Singlemode wavelengths and CWDM transmitters variants. This allows up to 96 audio channels to be carried on a single fibre. It can also be used to combine complex multiple multistandard video and audio formats unidirectionally or bidirectionally on one single fibre.
The BB600R is contained in a 1RU 19" rack-mounting frame with integral power supply.
