Small and Powerful

The Cambridge Qt® E-P-W-16-4 Active Emitter provides sound masking and clear reproduction of paging and music signals simultaneously. The new direct field emitter speaker offers a wider frequency range than previous models, all while being small and powerful. Once installed in a finished or open ceiling, it's virtually invisible. It also offers uniform direct field masking.

Uniform Direct Field Masking

Traditional sound masking systems often rely on bulky loudspeakers, similar in size to paint cans, to create sound that bounces off the ceiling and indirectly spreads throughout a room. In contrast, the Qt Active Emitter is compact and streamlined, using Cambridge Sound Management's unique patented direct field Quiet Technology to evenly distribute 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.
