The Cambridge Qt X 300/300D control module is a versatile device that functions as a sound masking generator, controller, third-octave band equalizer, and amplifier. It comes equipped with two auxiliary audio inputs that allow for the distribution of audio from paging controllers and background music players. The Qt X 300/300D has the ability to control up to three zones of Qt standard or active emitters. This compact three-zone networkable controller is ideal for installations covering up to 36,000 square feet (3,345 m2). Each zone can be adjusted independently for masking and aux audio levels and spectra. Both models are fully compatible with Biamp’s SageVue™ system management software. When multiple controllers are included in a single system, audio inputs can be shared across all controllers via AVB or Dante (300/D).
