BSS BLU-320 I/O Expander with BLU link and CobraNet

The BLU-320 is the card-based I/O expander that brings CobraNet audio networking into a Soundweb London system. Four slots take any mix of analog input, analog output, digital input, digital output, AEC input and telephone hybrid cards in banks of four, for up to 16 channels of configurable I/O from a single rack space unit, with an LCD front panel for local status and setup.

CobraNet runs on primary and secondary ports for fault tolerance, with control kept on a separate Ethernet port so the audio and control networks can be split or combined as the install needs. The 256-channel BLU link bus carries audio to the rest of the Soundweb London system over standard Cat 5e for up to 100 m between devices, or past 40 km through fiber media converters. Twelve control inputs and six logic outputs bring it into a GPIO-driven control system, and the whole unit is configured from HiQnet Audio Architect.
