The BSS BLU-50 brings the robust processing power and open-architecture DSP flexibility of the Soundweb London series into an economical, half-rack width form factor. Featuring a fixed analog configuration of 4 line/mic inputs with software-selectable +48V phantom power and 4 analog outputs, the BLU-50 provides complete control over signal routing, equalization, dynamics, and system logic.

At the heart of the unit is HARMAN's low-latency, fault-tolerant BLU link digital audio bus, which carries 48 channels of uncompressed 24-bit/48kHz audio over standard Cat5e cabling up to 100 meters. Up to 60 BLU link–compatible devices can share channels on a single network ring, making the BLU-50 an ideal standalone processor or an expandable edge-node for larger Soundweb London systems.

Key Features:

Flexible I/O Configuration: 4 electronically balanced mic/line analog inputs with selectable +48V phantom power and 4 balanced analog outputs on Phoenix connectors.
High-Bandwidth Digital Audio Bus: Integrated 48-channel BLU link bus with low-latency passthrough for simplified matrix distribution.
Integrated GPIO & Third-Party Control: Includes 12 control inputs, 6 logic outputs, and an RS-232 port for seamless integration with wall controllers and AV automation systems.
Versatile Power Options: Can be powered using the included 12VDC power supply or remotely via Power over Ethernet (PoE+).
Flexible Mounting: Compact half-rack chassis allows for rack-mount, surface-mount, or under-desk installation.
Comprehensive Software Management: Fully configured and monitored using HiQnet software architectures.
