Cambridge Sound Management Qt Active Emitter for Sound Masking, Paging and Music Applications

Small and Powerful

The new Qt® Active Emitter is a single-source Emitter capable of both sound masking and simultaneous clear reproduction of paging and music signals. It provides higher SPL and a broader frequency range than previous direct field Emitter offerings in a small, powerful speaker that’s virtually invisible once deployed in finished or open structure ceilings.

Uniform Direct Field Masking

Traditional sound masking systems use large loudspeakers the size of paint cans to reverberate sound off of the ceiling deck that indirectly distribute masking sound into an environment. In contrast, the small, sleek Qt Active Emitter utilizes Cambridge Sound Management’s patented direct field Quiet Technology to deliver uniform sound masking directly into the workspace.

Clear, Articulate Paging and Background Music

Another benefit of direct field technology is improved audio clarity for paging and music. Because pages are being emitted directly into the environment, they’re clearer and easier for listeners to understand. Music sounds better too because the speaker is facing the listener instead of being played through a ceiling material. The Qt Active Emitter is the only sound masking loudspeaker that’s a complete masking, paging, and music solution for office environments.

The Favorite Installation Choice of Integrators

The Qt Active Emitter uses the same control modules and cabling infrastructure that made QtPro™ the number one sound masking system choice of companies worldwide as well as the favorite installation choice of integrators. As a result, QtPro remains the easiest sound masking system to install and calibrate, regardless of whether the Active Emitter or original Emitter is used—a true plug and play experience with preset sound masking curves designed specifically for each emitter type.

• Plenum-rated, UL-listed, and complies with UL 2043
• Delivers four uncorrelated audio channels to reduce phasing/comb-filtering
• Comes standard with a slip-ring mount for acoustical tile mounting
• Rear DIP switches reduce volume by 4.5 dB in 1.5 dB increments if needed
• Compatible with the Qt 300 and Qt 600 control modules
• Control via web-based management from any device
