BSS BLU-GPX GPIO Expander
The BSS BLU-GPX is a professional control interface built for complex audio system integration and synchronized studio automation. Its compact 1U rackmount form factor houses extensive I/O capabilities managed through an intuitive front panel and networked configuration, making it essential for studios and installations requiring precise GPIO control, multi-device synchronization, and reliable communication across networked audio equipment.
Control Architecture & I/O Specifications
This unit delivers comprehensive control connectivity with 36 control inputs and 23 logic outputs, plus 8 integrated relay outputs with both Normally Open and Normally Closed terminals for switching applications. The 3.5mm Phoenix/Combicon connectors provide standard professional wiring compatibility, while 47 common connections and 12 reference connections simplify integration with external audio gear, outboard processors, and studio control systems in both 2-wire and 3-wire configurations.
Network Connectivity & Power Distribution
Dual PoE-enabled Ethernet ports support configuration, control, and monitoring over standard network infrastructure with IEEE 802.3af power delivery as primary power, backed by an optional 12VDC external power supply (19W) for redundant operation. This dual-path design ensures system reliability in studio environments where communication and power continuity are critical to session workflow and uninterrupted recording operations.
