The Cambridge Qt® X 300/300D control module is a sound masking generator, controller, third-octave band equalizer and amplifier, with two auxiliary audio inputs to allow for distribution of audio from paging controllers and/or (background) music players. The Qt X 300/300D controls up to three zones of Qt standard or active emitters. The Qt X 300/300D control module is a compact three-zone networkable controller suitable for installations of up to 36,000 square feet (3,345 m2). Each zone can be independently adjusted for masking and aux audio levels and spectra. Both models feature full compatibility 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 Dante.
