Cambridge Sound Qt 100 1-zone sound masking control module - 911.0823.900

Product Overview

The Cambridge Sound Qt 100 (part number 911.0823.900) is a single-zone sound masking control module that combines a masking generator, controller, and amplifier in one compact wall-mounted unit. It covers spaces up to 12,000 sq ft (1,115 m²) and supports up to 120 Qt emitters on a single zone. Front-panel controls make volume adjustment quick, with no software required for day-to-day operation. An auxiliary audio input adds paging or background music distribution to the same emitter network.

Product Description

The Qt 100 anchors the QtPro direct-field sound masking system for small and mid-sized spaces. Unlike white noise, the masking signal is shaped to the frequency range of human speech, making it more effective at protecting speech privacy and more acoustically comfortable for occupants. Direct-field Quiet Technology projects the masking signal from emitters facing the workspace rather than bouncing it through the ceiling, which produces uniform coverage and reduces the need for costly construction or sound-blocking materials. Each emitter installs in under 15 minutes in any ceiling type, making the Qt 100 straightforward to retrofit into existing workspaces. The module mounts on a wall, measures just 7 x 3.5 x 0.875 inches, and weighs 6 ounces. Volume is adjustable by zone and audio source from the front panel, a software panel lock prevents tampering, and a safety alarm integration input mutes masking during alarm events. The fixed terminal block audio input accepts a paging controller or music player feed. The system is GreenSpec listed as an energy-efficient masking solution. Pair the Qt 100 with emitters from the Cambridge Sound collection.

FAQ

How large a space can the Qt 100 cover?
One zone up to 12,000 sq ft (1,115 m²), supporting a maximum of 120 Qt emitters.

Is sound masking the same as white noise?
No. The Qt 100's masking signal is shaped to the frequency range of human speech, so it covers conversations more effectively and is more acoustically comfortable than white noise.

Can it play paging or music?
Yes. A fixed terminal block auxiliary input accepts a paging controller or background music player, distributed through the same emitter network.

How is the Qt 100 controlled?
Directly from the front panel, with volume adjustable by zone and audio source. A software panel lock prevents tampering.

Is it hard to retrofit into an existing office?
No. Each direct-field emitter installs in under 15 minutes in any ceiling type, and the wall-mounted module requires no equipment rack.
