Cambridge Sound Qt X 600D 6-zone sound masking control module - 911.0217.900

Product Overview

The Cambridge Sound Qt X 600D (911.0217.900) is a 6-zone sound masking control module that combines masking generation, control, band equalization, and amplification with Dante and AVB media networking. Sound masking raises the ambient background level with engineered sound so nearby speech becomes unintelligible, protecting privacy and reducing distraction. Two auxiliary audio inputs distribute paging and background music through the same emitter network. The compact, networkable controller supports installations up to 72,000 square feet (6,690 m²).

Product Description

The Qt X 600D drives up to six zones of Qt standard or active emitters, with each zone independently adjustable for masking level, aux audio level, and spectrum. That zone granularity lets a single controller tune open work areas, corridors, and private suites differently across a large floor plate. Four non-correlated masking sources per zone produce uniform, comfortable coverage without phasing artifacts. The module supports AVB or Dante media networks, and when multiple controllers are deployed in one system, audio inputs are shared across all controllers over the network, simplifying paging and music distribution at campus scale. Configuration is handled from the front-panel LCD or a web interface reachable from any web-enabled device, with a third-party control API over Ethernet for integration into building control systems. Auto ramping and event scheduling adjust masking levels through the day, a contact closure integrates with fire alarm systems, and the unit is fully compatible with Biamp SageVue system management software. The wall mount bracket is included, with an optional rack mount available. Pair it with emitters from the Cambridge Sound range.

Key Features

• Six independent zones — separate masking and aux audio levels and spectra per zone across up to 72,000 sq ft.
• Dante and AVB networking — share audio inputs across multiple controllers in large or multi-floor systems.
• Two audio inputs — distribute paging and background music through the masking emitter network.
• Four non-correlated masking sources per zone — uniform, comfortable coverage without audible patterning.
• Flexible emitter support — drives both Qt Standard and Qt Active emitters; 50 active or 60 standard emitters per cable run.
• Scheduling and auto ramping — time-based masking levels with smooth transitions and a built-in NTP-synced clock.
• Web and API control — front-panel LCD, browser interface from any device, and third-party control API over Ethernet.
• Life-safety integration — contact closure ties masking mute to fire alarm systems.
• Compliance and warranty — CE marked, ETL listed, RoHS compliant, TAA compliant, GSA eligible, five-year manufacturer warranty, made in the U.S.A.

Typical Applications

• Large open-plan offices spanning multiple departments or floors
• Private office corridors and conference room clusters
• Hospitals and clinics protecting patient conversations (HIPAA speech privacy)
• Call centers with distinct acoustic zones
• Financial, legal, and government facilities requiring networked, scheduled masking

Frequently Asked Questions

How much area can the Qt X 600D cover?
Up to 72,000 square feet across six zones, with two cable runs per zone supporting up to 50 active or 60 standard emitters per run.

What is the difference between the Qt X 600 and 600D?
The 600D adds Dante media networking; both support AVB. Choose the 600D when your facility standardizes on Dante audio transport.

Can it distribute paging and music?
Yes. Two auxiliary inputs feed paging controllers and background music players, and inputs can be shared across multiple controllers over AVB or Dante.

How is the system controlled?
Via the front-panel LCD, a web interface from any web-enabled device, Biamp SageVue management software, or a third-party control API over Ethernet.

What warranty applies?
The Qt X 600D is covered by the manufacturer's five-year warranty. Request a quote from Creation Networks for system design and emitter counts.
