The Qt® 300 comes standard with a wall mount for easy access to the unit’s connections
The Qt® 300’s front LCD screen displays system and individual zone information
The Qt® 300’s front panel controls allow users to easy modify the system settings
Each zone is comprised of up to two runs. Each run can power up to 60 Qt Emitters
The Qt® 300 uses standard CAT 3 or higher cables with RJ-45 connectors
The Qt 300 uses a fixed terminal block to connect to paging or music sources
The Qt 300’s ethernet port allows users to access the units control software, set up email alerts and sync the unit’s internal clock
The Qt 300 features three independent zones allowing for differing masking, paging & music volume levels
The Qt 300 features a front panel lock switch to prevent unauthorized system modifications
A fixed terminal block contact closure mutes masking and music when connected to a preexisting emergency paging unit

The Qt® 300 is ideal for medium multi-zone spaces of up to 36,000 square feet (3,345 m2). This system is capable of covering up to 3 diverse areas in buildings needing improved speech privacy.

This robust and feature-rich system is easy to control and maintain. Users can adjust system settings via the easy-interface front panel, and can also set up error reporting and establish time dependent masking levels via their PC, Mac or tablet device using the intuitive Qt® Monitoring and Control Software. Additionally, the Qt 300 is an integrated solution offering sound masking along with paging and music via the two auxiliary audio inputs.

Qt 300 uses sound masking, an alternative to white noise that is more acoustically comfortable than white noise or pink noise.

Qt System Installation

  • Qt Emitters™
  • The backbone of the Qt® sound masking system. These emitters deliver 4 incoherent audio channels making the Qt system the best sound masking system on the market. The standard mounting is for acoustical tile ceilings.
  • Universal Bracket
  • This enclosure is used for mounting the Qt emitter to the wall or ceiling.
  • Beam Bracket
  • This enclosure is used for mounting the Qt emitter to exposed I-beams.
  • Drywall Mount
  • This enclosure is used for mounting the Qt emitter into drywall ceilings.
  • Conduit Mount
  • This enclosure is used for mounting the Qt emitter into ceilings in regions requiring conduit mounting.
  • Plenum Back Can
  • This enclosure is used for mounting the Qt emitter into acoustic ceiling tile in regions with special fire and/or conduit requirements.
  • The rack mount kit gives the ability to easily integrate into existing equipment racks.
  • The Qt Room Control can be used to adjust the sound masking level with 6 discrete level selections (including off) for an individual room or space with 2-8 emitters
    The Qt® 300 comes standard with a wall mount option. The wall mount gives users quick and easy access to the Qt 300’s connections and ports without having to remove the unit from the wall.
    Users can choose to install the Qt 300 into an existing equipment rack
    Qt 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. Emitters are plug-and-play, daisy-chained together with CAT-3, plenum-rated cables. We supply with every emitter, pre-terminated CAT3 cables with industry standard RJ-45 connectors.
