Used BSS FDS-355

The BSS FDS-355 Omnidrive is a loudspeaker management system used to optimise sound in live events and fixed installations. It gives sound engineers and event technicians precise control over crossover settings, EQ adjustments, and time alignment. Its multiple input and output options support complex audio routing, making it a practical tool for managing loudspeaker systems across a range of venue sizes and configurations.

The FDS-355 is made by BSS Audio, originally Brooke Siren Systems, a British professional audio brand founded in 1979 and now part of Harman Professional Solutions. BSS is known for signal processing equipment including crossovers, compressors, limiters and networked digital signal processors. The FDS-355 Omnidrive sits within that signal processing tradition, addressing loudspeaker management specifically for live and installed audio applications.

Yes, the FDS-355 is designed for both contexts. Its signal processing capabilities, including crossover control, EQ and time alignment, are relevant whether the unit is deployed for touring live sound or integrated into a fixed installation. Its compact, durable construction also makes it practical to transport and set up for live use, rather than being limited to rack-mounted permanent systems.

Confirm the unit powers on fully and that all inputs, outputs and processing functions, including crossover, EQ and time alignment controls, operate correctly. Check the condition of the interface controls and any rear-panel connectors. Used units vary in condition from fair to excellent, so review the seller's description carefully.
