Description
Biamp Cambridge Qt X 300 3-Zone Sound Masking Control Generator
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 three 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 input can be shared across all controllers via AVB or Dante (300/D).

Frequently Asked Questions
When should the Qt X 300 be used instead of a single-zone sound masking controller?
The Qt X 300 is better suited for larger or more complex spaces because it supports up to three independently adjustable zones and covers installations up to 36,000 square feet.
Can each zone be adjusted separately?
Yes. Each zone can have independent masking and auxiliary audio levels and spectra, which helps tune different areas of a facility separately.
What audio sources can be connected to the Qt X 300?
The controller includes two auxiliary audio inputs for paging controllers and background music players.
What type of emitters work with the Qt X 300?
The Qt X 300 is compatible with Qt Standard emitters and Qt Active emitters.
How does the Qt X 300 support more advanced tuning?
It combines a sound masking generator, controller, third-octave band equalizer, and amplifier, giving installers more control over masking and audio performance.
Can the Qt X 300 be managed over a network?
Yes. It includes dual network ports, web interface control, an Ethernet-based third-party control API, and compatibility with Biamp SageVue system management software.
Can multiple controllers share audio?
Yes. In multi-controller systems, audio input can be shared across controllers through AVB or Dante on the 300/D version.
Does the Qt X 300 support scheduling and automated behavior?
Yes. It supports auto ramping, event scheduling, and a built-in clock with NTP support.
