Description
The Harman Soundcraft BLU-326DA Soundweb London Networked I/O Expander is a powerful, configurable DSP platform designed for scalable, networked audio systems. Featuring Dante® / AES67 audio transport and a high-bandwidth, fault-tolerant BLU link digital audio bus, the BLU-326DA serves as a flexible backbone for commercial AV, installed sound, conferencing, and life safety applications.
With four configurable I/O card slots, the BLU-326DA supports analog, digital, AEC, and telephone hybrid card options—allowing designers to tailor the system for virtually any project requirement. Analog input cards offer software-selectable gain up to +48 dB and per-channel phantom power, while digital cards support AES/EBU and S/PDIF formats with multiple clocking and synchronization options.
Dante and AES67 compatibility enable seamless integration with modern IP-based audio networks, including support for Dante Domain Manager. Dual Dante ports provide primary and secondary connections for network redundancy, while a separate Ethernet port handles control and monitoring.
The integrated 256-channel BLU link digital audio bus delivers low-latency, fault-tolerant audio over standard Cat5e cabling up to 100 meters between devices. Fiber optic media converters can extend distances beyond 40 km, making it ideal for large campus or enterprise installations.
Configured through HiQnet™ London Architect, the BLU-326DA provides intuitive drag-and-drop design, extensive logic processing, and comprehensive third-party control integration via GPIO, RS-232, and the Soundweb London Interface Kit.
Designed for reliability and performance, the BLU-326DA is EN 54-16 compliant for life safety applications and built to serve as a core building block within the Soundweb London ecosystem.
