Sound Masking | Paging | Music

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.

Features 

  • Active electronics power the speaker
  • Ported enclosure design allows lower frequency extension down to 125 Hz octave band for sound masking and 115 Hz for paging and music
  • 17 dB louder than previous direct field emitter offerings
  • 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

Benefits

  • Delivers superior uniformity which leads to a more comfortable sound masking experience and clear, quality office paging and background music
  • Small but powerful speaker that’s virtually invisible once deployed in finished or open structure ceilings
  • Utilizes the same control modules, cabling infrastructure, and speaker driver size as other Cambridge Sound Management systems, ensuring QtPro remains the easiest sound masking system to install and calibrate
  • Provides new opportunities for sound masking system customization and optimization
  • Features an extended sound masking spectrum for additional comfort
  • Ability to use both the Qt® Active Emitter and original Qt Emitter on the same control processor simultaneously, if needed (requires separate zones)
  • Feel confident knowing the Qt® Active Emitter has the same uniformity, zoning and direct-field sound masking as our other high quality QtPro™  solutions trusted by more than 15,000 customers in over 30 countries
  • Direct-field is an efficient, effective, and a more affordable approach to sound masking, paging, and music reproduction

Key Facts

  • 125 Hz frequency response for sound masking
  • 115 Hz frequency response for music playback and paging
  • 74 dB SPL at 1 meter distance
  • Requires 600 Watt 3-zone power supply and power injector accessories to power the Qt® Active Emitter
  • 5 Year Warranty
  • Over 15,000 customers have used Cambridge Sound Management products in over 30 countries

  • Qt® Active Emitter is adjustable, giving users greater flexibility in laying out their Qt system. Adjustable emitters allow users to reduce the volume level of an individual emitter by up to 4.5 dB in 1.5 dB decrements. The adjustable emitter is appropriate for individual spot adjustments, or creating micro zones down to 100 square feet (9.3 m2) of space.
  • Qt® ACTIVE EMITTER INSTALLATION
    Qt® Active Emitters are installed along a simple grid pattern based on ceiling height. For a standard 9’ (2.75 m) ceiling, emitters are laid out on a 10’ x 10’ (3 m x 3m) grid. Emitters can be installed into standard ceiling tiles ranging from 0.5” to 1.5” (1.3 cm – 3.8 cm) thick. The Qt Active Emitters should be connected to a power supply and power injector.
