Qt® Emitters are the backbone of the QtPro™ sound masking system. Qt Emitters are wide dispersion (nearly 180 degrees) direct field loudspeakers with 1.25” (3.17 cm) 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 QtPro systems the most intelligently engineered and most effective sound masking systems on the market today.
