Qt Active Emitters are wide dispersion (nearly 180 degrees) direct field devices with 1.25-inch (3.17 cm) drivers capable of simultaneous reproduction of both sound masking and clear audio sources such as paging signals. Patented direct field technology ensures both uniform, comfortable sound masking as well as clear, articulate paging in a device that’s virtually invisible once deployed in finished or open structure ceilings.
The Qt Active Emitter features onboard active electronics to power the emitter and a ported enclosure design allowing lower frequency extension to the 100 Hz octave band. Power is delivered via an external power supply and power injectors, both available as accessories.
Active Emitters deliver four uncorrelated audio channels, automatically eliminating phasing. Active Emitters are plenum-rated, ETL listed, and comply with UL 2043. Each Active 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 Cambridge Qt® X systems the most intelligently engineered and most effective sound masking systems on the market today.
