BSS BLU-102 Conferencing Processor with AEC and Telephone Hybrid

The BLU-102 is the fixed-configuration conferencing processor in the Soundweb London range: 10 analog inputs with per-channel 48 V phantom, 8 analog outputs, and an RJ-11 port that connects directly to a POTS, PSTN or analog PBX line. Everything above that is programmed in HiQnet Audio Architect from the same drag-and-drop palette of processing and logic objects as the rest of the family.

Eight independent AEC algorithms run on board, applied to local analog inputs or to signals arriving over the bus, each with its own reference so one chassis can serve several rooms. Automatic gain control holds microphone levels and noise cancellation strips steady-state noise such as projector fans out of the path. Twelve control inputs and six logic outputs handle GPIO, and its 48-channel bus maps onto channels 1 to 48 of the wider 256-channel BLU link bus.
