Inside the Design

Employees can be easily distracted by noise from co-workers, office equipment, telephones, and outside noises. This multi-zone office sound masking system with background music and paging capabilities greatly reduces those distractions and can overcome problems such as poor acoustics and intrusive facility noises. Ideal for call centers, corporate business offices, sales floors, and open floor plan offices, this commercial office sound masking system will increase acoustical office comfort, resulting in an overall more productive work environment and less stressed employees and customers.

Sound System Features:

• Up to 3 zones with approximately 3,200 sq ft of coverage
• Clear, quality office paging and background music capabilities
• Delivers superior uniformity for comfortable sound masking experience
• Small, powerful speakers that are virtually invisible in open ceilings
• Features an extended sound masking spectrum for additional comfort
• Sound masking equipment that's easy to install and calibrate
  
  

About the System Components

Cambridge Qt Active Emitters

The Cambridge Qt Active Emitter is a single-source Emitter loudspeaker capable of sound masking, paging and music. The Cambridge Qt sound masking emitters are the backbone of the Qt Quiet Technology Sound Masking System. Qt emitter sound masking speakers are smaller than a coffee mug. Delivers superior uniformity which leads to a more comfortable sound masking experience and clear, quality office paging and background music.

Cambridge Qt X 300 Controller

The Cambridge Qt X 300 control module is a sound masking generator, controller, third-octave band equalizer and amplifier, with two auxiliary audio inputs to allow for distribution of audio from paging controllers and/or (background) music players. The Qt X 300 controls up to three zones of Qt standard or active emitters.

Cambridge Active Emitter Power Injector

The Active Emitter Power Injector is used to combine DC power from the Active Emitter Power Supply with the audio signal from the QtPro module in order to provide a powered "signal" for the Qt® Active Emitter.

Cambridge Active Emitter Power Supply

The Cambridge Active Emitter Power Supply is an external power supply that provides DC power to the Qt® Active Emitter through the Active Emitter Power Injector. It houses three 14/2 conductor cabling outputs that each power up to 50 Qt Active Emitters for a total of 150 Active Emitter maximum.
