The Cambridge Qt X 800 control module, an eight-zone sound masking generator, controller, band equalizer and amplifier, is designed specifically for the plenum space and requires PoE+ power supply; includes support for AVB media networks, with two auxiliary audio inputs to allow for distribution of audio from paging controllers and/or (background) music players.

The Qt X 800 controls sound masking speakers/emitters in both direct-field and indirect (in-plenum) installations—or a mix of both. Each of the eight amplified output speakers/emitters can be independently adjusted for masking and aux audio levels and spectra.

When multiple Qt X controllers are included in a single system, audio inputs can be shared across all controllers via AVB.

The Qt X 800 & Qt X 800D comply with the United States Trade Agreement Act (TAA), allowing it to be included in GSA Schedule contractors’ sales bids for the U.S. federal government.
