Qt® Emitters are the backbone of the Cambridge Qt X sound masking system.
Qt Emitters are wide dispersion (nearly 180 degrees) direct field loudspeakers with 1.25 inch (3.17cm) drivers and are smaller than a coffee mug. Emitters have DIP switches that allow their volume to be reduced 9 dB in 3 dB decrements. Emitters deliver four uncorrelated audio channels, automatically eliminating phasing. Emitters are plenum-rated, ETL listed, and comply with UL 2043.
Each Emitter comes standard with a slip-ring mount for acoustical tile mounting. These features, along with plug and play installation and easy configuration capability, make Qt X systems the most intelligently engineered and most effective sound masking systems on the market today.
