Product description The Soundweb London BLU-101 Conferencing Processor with AEC from BSS Audio is a 1RU configurable signal processing interface, featuring AEC (Audio Echo Cancellation) algorithm. This interface features 12 analog inputs and 8 analog outputs. It has a high bandwidth and fault tolerant digital audio bus. This unit is controlled via the Soundweb BLU link Ethernet CAT5 connection.
The BLU-101 has an open architecture which is fully configurable through the HiQnet London Architect configuration and control software. The simple design software environment includes processing and logic objects, and a "drag and drop" configuration method.
The Conferencing Processor features dedicated AEC processing for up to 12 independent AEC algorithms. The AEC algorithm can be applied to signals coming from the local analog inputs or from the digital audio bus. 12 individual AEC references (one per algorithm) allow the user to provide a solution for multiple conferencing spaces using a single device. The BLU-101 also features Automatic Gain Control (AGC) and Noise Cancellation (NC) which are provided per AEC algorithm. AGC is designed to ensure that the microphone levels remain at an optimum level, and NC removes steady state noise (such as from a projector fan or air conditioning device) from the signal path.
This processor features a low latency, fault tolerant digital audio bus of 48 channels which uses standard CAT5e cabling giving a distance of 100m between compatible devices. Fiber media converters can be used to increase the distance between devices to over 40km. The systems analog inputs provide software configurable gain in 6dB steps up to +48dB per channel and software selectable Phantom Power per channel. The Phantom Power, Signal Present and Clip information per channel are on the front panel LED indicators, eliminating the need for a PC. A bi-directional locate function allows devices to be identified both from and within HiQnet London Architect software.
The systems 12 control inputs and 6 logic outputs, allow the BLU-101 to be integrated with GPIO compatible devices. The BLU-101 is compatible with the entire Soundweb London family and its 48 channel digital audio bus represents channels 1-48 of the larger 256 channel digital audio bus when integrated with the BLU-800 and BLU-160 processors, as well as the BLU-320, BLU-120, BLU-BIB and BLU-BOB expanders. - 12 Analog inputs (with 48V phantom power per channel) and 8 analog outputs
