System installers in search of a high-quality conferencing processor with AEC and VoIP will be impressed with the BSS Audio Soundweb London BLU-103, which offers a fixed configuration of 8 analog inputs and 8 analog outputs, a Voice over IP (VoIP) interface, configurable signal processing, AEC processing, and a high bandwidth, fault tolerant digital audio bus. The VoIP port enables the BLU-103 to interface with two VoIP (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 300 feet between compatible devices. Fiber media converters can be used to increase the distance between devices to over 24 miles. The BLU-103 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-806, BLU-805, BLU-800, BLU-326, BLU-325, BLU-320, BLU-160, BLU-120, BLU-BIB, and BLU-BOB devices.

Analog Inputs provide software configurable gain in 6 dB steps up to +48 dB per channel and software selectable phantom power per channel. Phantom power, signal present and clip information per channel is easily accessible, without the requirement for a PC, from clear front-panel LED indication. A bidirectional locate function allows devices to be identified both from and within HiQnet Audio Architect. 12 Control Inputs and 6 Logic Outputs allow the BLU-103 to be integrated with GPIO compatible devices. The Soundweb London Interface Kit, comprehensive documentation which details how Soundweb London systems can be integrated with third-party control systems, is included within the installation of HiQnet Audio Architect. The BLU-103 and the other members of the Soundweb London family provide the building blocks of the perfectly tailored system solution.
