Small and Powerful
The new Cambridge Sound E-A-B-16-4 Standard 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, virtually invisible speaker once deployed in finished or open structure ceilings.
Uniform Direct Field Masking
Sound masking systems have traditionally used large loudspeakers, similar in size to paint cans, to create sound that reverberates off the ceiling deck. This method indirectly distributes the masking sound throughout the environment. However, the Qt Active Emitter is a small and sleek device that uses Cambridge Sound Management's patented direct field Quiet Technology to provide even sound masking directly into the workspace.
Clear, Articulate Paging and Background Music
Direct field technology has the advantage of enhancing audio clarity for paging and music. With direct emission of pages into the environment, listeners can better understand what is being said. Additionally, music sounds superior because the speaker is aimed towards the listener instead of playing through a ceiling material. For office settings, the Qt Active Emitter is the sole sound masking loudspeaker that provides a comprehensive solution for masking, paging, and music needs.
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.
