Genelec UNIO Personal Reference Monitoring System

The Genelec UNIO Personal Reference Monitoring (PRM) system combines the 9320A SAM Reference Controller with the 8550A professional reference headphones. Together they enable calibrated headphone monitoring using Genelec GLM software, providing a personal listening experience that matches the tonal accuracy of Genelec loudspeaker monitoring systems. Designed for situations where loudspeaker monitoring is impractical, including late-night sessions, shared spaces, and location work.

How It Works

The 9320A Reference Controller connects to your audio source and to the GLM network. GLM software calibrates the headphone output using a target curve derived from Genelec's loudspeaker reference, compensating for the 8550A's headphone transfer function. The result is a headphone monitoring experience that tonally aligns with calibrated Genelec speakers in your room.
