The BSS Audio Soundweb London BLU-120 is a high-capacity digital signal processor designed as a central processing engine for large-scale, complex audio installations. It serves as a powerful node within the Soundweb London ecosystem, combining extensive digital audio networking with a substantial number of configurable analog inputs and outputs. This model is distinguished by its twelve balanced analog inputs and twenty balanced analog outputs, providing exceptional I/O density for applications requiring numerous independent zones, mixes, or processing paths, such as major performing arts centers, corporate headquarters, stadiums, and broadcast facilities.

At the heart of the BLU-120 is a sophisticated processing platform capable of handling intricate mixing matrices, comprehensive equalization, dynamics processing, and delay across all channels. It integrates fully with the BLU Link digital audio bus, which allows for the seamless addition of hundreds of audio channels over a single Cat-5e cable, enabling distributed system architectures. The device is programmable via an intuitive, drag-and-drop software interface, allowing system designers to build custom signal flows, create user control interfaces, and implement automations that respond to triggers or schedules. This flexibility makes it capable of managing everything from simple zone paging to highly detailed multichannel soundscapes.

The processor is built for reliability in 24/7 operation, housed in a 2U rack-mount chassis with a fanless design for silent operation. It includes multiple control and data ports, such as Ethernet and RS-232, for integration into broader control systems and remote management. The BSS Audio Soundweb London BLU-120 stands as a cornerstone for advanced audio system design, offering the channel count, processing power, and networking capability required to address the most demanding acoustic and operational challenges in professional fixed installations.
