PRODUCT DESCRIPTION

Biamp’s Cambridge Qt

®

 X Series is a complete, all-in-one sound masking 

solution that delivers the flexibility, reliability, and ease of installation that 

integrators desire. It is engineered to incorporate direct-field technologies, 

making the Qt X ideally suited for office environments. Qt X is easily interfaced 

with a building’s life-safety system out of the box, ensuring proper coordination 

during emergencies.
All models of the Qt X control modules include a sound masking generator, 

controller, third octave band equalizer and amplifier with two analog audio inputs. 

This allows for distribution of audio from paging controllers and/or (background) 

music players, one digital media input (RJ45 Ethernet port), and 3 or 6 analog 

output channels (depending on the Qt X model) to connect to sound masking 

emitters or speakers.

Qt X 300 

and

 Qt X 600:

 Use direct field devices (Qt Standard or Active Emitters). 

The emitters point downward above the listener's head for direct, unimpeded 

audio signal. The Qt X 300 control module is a compact three-output controller 

suitable for installations of up to 36,000 square feet (3,345 m

2

). The Qt X 600 

control module is identical in features and functions yet supports six outputs of 

sound masking and audio installations of up to 72,000 square feet (6,689 m²). 

Outputs can be assigned to a zone and then the zones are adjusted for masking 

and audio levels and spectra. Qt X 300/600 models have "preset" optimized 

sound masking spectra for use with Qt Emitters. Additional configuration is 

available from a web-based control interface or from a remote desktop leveraging 

the unit’s network connectivity with the Qt X software. 
The "D" models of each controller (Qt X 300D/600D) will be available in a future 

release. They support Dante

®

 audio stream inputs and are AES67 compatible.    

The Qt X web-based management software provides an intuitive interface 

for setup and programming of a Qt X sound masking system. For information 

related to this software interface, see Qt X

 Web help

.

Unless otherwise noted, all installation, set up and use instructions apply to the  

Qt X family of control modules (Qt X 300 and Qt X 600).
