The Cambridge Qt X 300 control module is a three-zone, networkable sound masking generator, controller, third-octave band equalizer, and amplifier supporting AVB media networking. With two auxiliary audio inputs, the Qt X 300 allows distribution of audio from paging controllers and background music players.
The Qt X 300 controls up to three zones of Qt Standard or Qt Active emitters and is designed for installations up to 36,000 square feet (3,345 m²). Each zone can be independently adjusted for sound masking and auxiliary audio levels and spectra.
When multiple controllers are included in a single system, audio inputs can be shared across all controllers via AVB or Dante (Qt X 300D).
The Qt X 300 complies with the United States Trade Agreement Act (TAA), allowing it to be included in GSA Schedule contractors’ sales bids for U.S. federal government applications.
