BSS Soundweb London BLU-101 Conferencing Processor with 12-Channel AEC

The BSS Soundweb London BLU-101 is a professional digital signal processor (DSP) designed for conferencing, teleconferencing, and commercial audio installations requiring advanced acoustic echo cancellation (AEC), flexible signal processing, and reliable audio distribution. Featuring 12 analog inputs, 8 analog outputs, and 12 independent channels of AEC processing, the BLU-101 provides a powerful solution for conference rooms, corporate meeting facilities, educational environments, and integrated AV systems.

Designed with an open-architecture processing platform, the BLU-101 allows audio system designers to create customized signal paths using HiQnet London Architect software. Its drag-and-drop configuration environment provides access to an extensive library of audio processing and logic functions, allowing integrators to tailor the processor to specific room acoustics, microphone arrangements, and conferencing requirements.

The BLU-101 incorporates 12 independent acoustic echo cancellation algorithms, each with its own reference signal. This allows the processor to support multiple conferencing spaces or complex microphone configurations while minimizing echo during two-way communication. Automatic Gain Control (AGC) and Noise Cancellation (NC) are included with each AEC channel to help maintain consistent microphone levels and reduce steady background noise from HVAC systems, projectors, and other equipment.

For larger integrated audio systems, the BLU-101 features a 48-channel low-latency, fault-tolerant Soundweb London digital audio bus. This high-bandwidth connection enables digital audio distribution between compatible Soundweb London processors using standard Category 5e cabling.

With 12 control inputs, 6 logic outputs, software-selectable phantom power, and front-panel status indicators, the BLU-101 provides the connectivity and flexibility needed for professional installed conferencing systems.

Features & Benefits

12-Channel Acoustic Echo Cancellation

The BLU-101 provides 12 independent AEC processing algorithms designed to reduce acoustic echo during conferencing and two-way audio communication. Each AEC channel supports an individual reference signal, allowing flexible configurations for multiple microphones and conferencing spaces.

Automatic Gain Control and Noise Cancellation

Integrated AGC helps maintain consistent microphone signal levels as participants speak at different volumes or distances. Noise Cancellation reduces steady background sounds such as air conditioning and projector fans, improving speech intelligibility.

12 Analog Inputs and 8 Analog Outputs

The BLU-101 features a fixed configuration of 12 analog inputs and 8 analog outputs, providing the connectivity needed for multiple conferencing microphones, external audio sources, amplifiers, and other installed audio equipment.

Software-Selectable Phantom Power

Each analog input provides software-configurable gain in 6 dB steps up to +48 dB, along with individually selectable 48V phantom power for compatible condenser microphones.

Open-Architecture DSP Processing

Using HiQnet London Architect software, system designers can configure audio routing, processing, mixing, and control logic through a drag-and-drop interface. This allows the BLU-101 to be adapted to a wide range of conferencing and commercial sound applications.

48-Channel Fault-Tolerant Digital Audio Bus

The Soundweb London digital audio bus provides 48 channels of low-latency audio transport between compatible devices. Standard Category 5e cabling supports connections up to 100 meters between devices, with longer distances possible through appropriate fiber media conversion.

Soundweb London System Integration

The BLU-101 can integrate with compatible Soundweb London processors and I/O expanders, including the BLU-800, BLU-320, BLU-160, BLU-120, BLU-BIB, and BLU-BOB. When connected to systems using the larger 256-channel Soundweb London audio bus, the BLU-101 operates on channels 1–48.

GPIO and Third-Party Control Integration

With 12 control inputs and 6 logic outputs, the BLU-101 supports integration with compatible external control devices, wall controllers, and automation systems. Documentation for third-party control integration is provided through the Soundweb London Interface Kit.

Front-Panel Monitoring and Device Identification

Front-panel LED indicators provide immediate access to phantom power, signal presence, and clipping information. A bidirectional locate function helps installers identify devices during configuration and troubleshooting.
