Biamp Cambridge Qt X 300
Deliver exceptional sound masking, paging, and background music coverage with the Cambridge Qt X 300, a three-zone, networkable controller that combines a sound masking generator, third-octave band equalizer, and amplifier into one powerful, scalable platform.
The Cambridge Qt X 300 is an all-in-one sound masking, paging, and audio distribution controller engineered for medium-sized installations up to 36,000 square feet (3,345 m²). Combining a sound masking generator, third-octave band equalizer, and integrated amplifier, it provides precise control over acoustic comfort and intelligibility in open-plan offices, healthcare environments, and other commercial spaces.
Each of the three independent zones supports Qt standard or active emitters, with separate adjustment for masking and auxiliary audio levels and spectra. With two auxiliary inputs, the Qt X 300 enables flexible paging and background music distribution, while system-wide synchronization is made possible through AVB or Dante networking (Qt X 300/D variant).
