BB600T 12 Channel Balanced Analogue Audio Multiplexer Audiopdf

bb600t

The BB600T is a 1RU sub rack for the transmission of twelve independent balanced line level analogue audio signals over a single fibre optical cable. All inputs are buffered then converted using full 24 bit A/D conversion then multiplexed onto a single optical data stream.

XLR connectors on the front of the unit 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 BB600T is available in multimode and singlemode variants to suit any fibre application. CWDM variants are also available allowing up to 96 audio channels to be carried on a single fibre. It can also be used to combine multiple multistandard video and audio formats unidirectionally or bidirectionally on one single fibre.
The BB600T is contained in a 1RU 19" rack-mounting frame with integral power supply.
