Cambridge Sound Qt X 800 8-zone sound masking control module - 911.0216.900

Product Overview

The Cambridge Sound Qt X 800 (part number 911.0216.900) is an 8-zone sound masking control module that serves as a masking generator, controller, third-octave band equalizer, and amplifier. It connects to AVB media networks, is powered over PoE+ with an optional 48 VDC input, and meets UL 2043 requirements for installation in air handling spaces. Each of its eight outputs carries its own non-correlated masking source for uniform coverage. The module is GSA eligible, TAA compliant, and manufactured in the U.S.A.

Product Description

The Qt X 800 controls sound masking emitters in direct-field installations, indirect (in-plenum) installations, or a combination of both, and is compatible with DynasoundPro loudspeakers. Two auxiliary audio inputs accept paging controller and background music feeds, and each of the eight amplified outputs can be independently adjusted for masking and aux audio levels and spectra. The module is fully compatible with Biamp's SageVue system management software and can be integrated into larger Qt X systems; when multiple controllers are deployed, audio inputs are shared across all controllers over the media network. Dual network ports separate media and control traffic, and a third-party control API is available over Ethernet. Auto-ramping, event scheduling, and a built-in clock with NTP support automate day-to-day operation, while a front-panel LCD with software panel lock provides local control and a contact closure integrates with fire alarm systems. A plenum mount bracket is included, with optional wall and rack mount brackets available. The unit is CE marked, ETL listed, RoHS compliant, and covered by Biamp's five-year warranty. Pair it with emitters from the Cambridge Sound collection.

Key Features

• Eight Masking Zones — independent level and spectrum adjustment on each amplified output.
• AVB Media Networking — shares audio inputs across multiple Qt X controllers in larger systems.
• PoE+ Powered — network-powered with an optional 48 VDC input for flexible installation.
• UL 2043 Plenum Rated — approved for air handling spaces; plenum mount bracket included.
• Eight Non-Correlated Masking Sources — one generator per output for a uniform, artifact-free masking field.
• Two Auxiliary Audio Inputs — distributes paging and background music alongside masking.
• Third-Octave Band EQ — adjustable equalization for masking and audio inputs.
• Fire Alarm Integration — contact closure mutes the system during alarm events.
• Scheduling and Auto-Ramping — event scheduling with gradual level transitions and NTP-synced clock.
• SageVue Management — Biamp SageVue compatibility plus a third-party control API over Ethernet.
• Government Procurement Ready — GSA eligible, TAA compliant, manufactured in the U.S.A.
• Five-Year Warranty — CE marked, ETL listed, and RoHS compliant.

Typical Applications

• Open offices — zoned masking across open floor plates with integrated paging and music.
• Private offices and conference rooms — per-zone control protects confidential conversations.
• Healthcare facilities — supports patient speech privacy in clinics and exam areas.
• Call centers — reduces speech distraction between adjacent workstations.
• Financial and legal offices — keeps client discussions private in professional suites.

FAQ

What is the difference between the Qt X 800 and Qt X 800D?
Both are 8-zone control modules; the 800D adds Dante media networking, while the Qt X 800 uses AVB. Feature sets are otherwise comparable.

How is the Qt X 800 powered?
It runs on PoE+ from a network switch, with an optional 48 VDC input, which simplifies above-ceiling installation.

Can it be mounted in the ceiling plenum?
Yes. It meets UL 2043 requirements for air handling spaces and includes a plenum mount bracket; wall and rack mount brackets are optional.

Does it handle paging and music as well as masking?
Yes. Two auxiliary audio inputs distribute paging and background music, each independently adjustable per zone for level and spectrum.

Can it scale beyond eight zones?
Yes. Multiple Qt X controllers can be combined in one system with shared audio inputs over the media network, managed through Biamp SageVue.
