BLU-103 Soundweb London Conferencing Processor with AEC and VoIP


Ships Directly from Manufacturer. Contact Us for Availability.

The Soundweb London BLU-103 offers a fixed configuration of 8 analog inputs and 8 analog outputs, a Voice over IP (VolP) interface, configurable signal processing, AEC processing, and a high bandwidth, fault tolerant digital audio bus.

The VolP port enables the BLU-103 to interface with two VolP (SIP v2.0 or later) lines.
The BLU-103 contains dedicated AEC processing for up to
8 independent AEC algorithms. The AEC algorithm can be applied to signals coming from the local analog inputs or from the digital audio bus. 8 individual AEC references (one per algorithm) allow the user to provide a solution for multiple conferencing spaces using a single device.

Automatic Gain Control (AGC) and Noise Cancellation (NC) are also provided per AEC algorithm. AGC ensures that 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 Category 5e cabling giving a distance of 100m between compatible devices. Fiber media converters can be used to increase the distance between devices to over 40 km.
