The BSS BSSBLU120M-US is a networked I/O expander designed for professional installed audio systems that require flexible input and output expansion across analog, digital, and AES/EBU domains. Built for integration into larger BSS BLU link networked audio architectures, the chassis provides four card slots that accept custom I/O cards, enabling you to configure exactly the connectivity your system demands without paying for unused channels.

Sound engineers and system integrators working in broadcast, live production, and installed venues rely on the BLU-120 to extend I/O reach across distributed audio networks. The modular card-based design means you can mix analog inputs with phantom power, digital inputs via AES/EBU or S/PDIF, and telephone connections all within the same single-rack-space chassis. This flexibility eliminates the need for multiple outboard devices and simplifies network architecture.

Mount the BLU-120 in any standard 19-inch rack and connect it to your BSS BLU link network. The expander integrates seamlessly with existing BSS signal processing and control workflows, reducing setup time and wiring complexity in complex multi-zone or multi-source installations.
