Description
The Soundweb London BLU-103 (BLU-103) is a high-performance conferencing processor designed for professional AV environments requiring advanced acoustic echo cancellation (AEC), VoIP connectivity, and scalable networked audio distribution.
Featuring 8 analog mic/line inputs and 8 analog outputs, the BLU-103 provides a fixed yet powerful configuration ideal for boardrooms, divisible meeting spaces, training rooms, and multi-room conferencing applications.
With a built-in VoIP interface supporting two SIP v2.0 (or later) lines, the BLU-103 seamlessly integrates into enterprise telephony systems. Dedicated AEC processing delivers up to eight independent AEC algorithms, each with Automatic Gain Control (AGC) and Noise Cancellation (NC), ensuring crystal-clear communication by maintaining optimal microphone levels and removing steady-state background noise such as HVAC or projector fans.
The processor includes a 48-channel, low-latency, fault-tolerant digital audio bus over standard Cat5e cabling, supporting distances up to 100 meters between devices — and over 40 km with fiber media converters. Fully compatible with the Soundweb London family, the BLU-103 integrates seamlessly into larger 256-channel system architectures.
Front-panel LED indicators provide immediate access to phantom power, signal present, and clip status without requiring a PC. Twelve control inputs and six logic outputs allow GPIO integration with third-party control systems, while configuration, control, and monitoring are handled through HiQnet Audio Architect™ software.
The BLU-103 delivers the building blocks for a perfectly tailored conferencing and installed audio solution.
