CAMBRIDGE Qt X 300/300D
SOUND MASKING CONTROL MODULE
The Cambridge Qt™ X 300/300D 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 300/300D controls up to 3 zones of Qt Standard or Active emitters. The Qt X 300/300D control module is a compact three-zone networkable controller suitable for installations of up to 36,000 square feet (3,345 m2). Each zone can be independently adjusted for masking and aux audio levels and spectra. Both models feature full compatibility with Biamp’s SageVue™ system management software. When multiple controllers are included in a single system audio inputs can be shared across all controllers via AVB or Dante (300/D).

ARCHITECTS & ENGINEERS SPECIFICATION
The controller shall consist of all electronics required for operating a sound masking system from a single accessible
location. Systems with distributed electronic packages above ceilings are not acceptable. The controller shall permit
password protected access for control and monitoring via LAN/browser interface. The controller shall provide three zones
and shall be sufficient to generate sound masking, audio control and audio power for up to 36,000 square feet (3,345 m2)
of coverage. The unit shall be capable of time-of-day masking level control; per-zone settings shall be available for day/
night levels and start times, ramping interval, and weekday/Sat/Sun behavior. Each audio output shall provide 4 noncorrelated
channels of masking noise to minimize comb filtering. The unit shall meet all requirements of Underwriters
Laboratories, the US and Canadian National Electrical Codes, FCC Part 15, and all pertinent UK and EU codes. The
controller shall be CE marked, UL listed, and shall be compliant with the RoHS directive. Warranty shall be 5 years. The
controller shall be Qt X 300/300D.
