Cambridge Sound Qt X 800D 8-zone sound masking control module - 911.0220.900

Product Overview

The Cambridge Sound Qt X 800D (part number 911.0220.900) is an 8-zone sound masking control module that integrates a masking generator, zone controller, third-octave band equalizer, and amplifier in one device. It supports Dante and AVB media networking and can be powered over PoE+ with an optional 48 VDC input. The module meets UL 2043 requirements for installation in air handling spaces, with a plenum mount bracket included. It is GSA eligible, TAA compliant, and manufactured in the U.S.A.

Product Description

The Qt X 800D generates sound masking for up to eight zones and works in both direct-field and indirect (in-plenum) emitter installations, with compatibility for DynasoundPro loudspeakers. Two auxiliary audio inputs distribute paging and background music alongside the masking signal, and each amplified output can be adjusted independently for masking and aux audio levels and spectra. Eight non-correlated masking sources — one per output — keep the masking field uniform and free of phasing artifacts. The module integrates with Biamp's SageVue system management software and can be combined with additional Qt X controllers in larger systems, sharing audio inputs across all controllers over the Dante or AVB network. Dual network ports separate media and control traffic, and a third-party control API is available over Ethernet. Operational features include auto-ramping, event scheduling, a built-in NTP-synced clock, a front-panel LCD with software panel lock, and a contact closure for fire alarm integration. It is CE marked, ETL listed, RoHS compliant, and backed by Biamp's five-year warranty. See compatible emitters in the Cambridge Sound collection.

Key Features

• UL 2043 Plenum Rated — meets requirements for installation in air handling spaces; plenum mount bracket included.
• Eight Non-Correlated Masking Sources — one generator per output for a uniform masking field.
• Two Auxiliary Audio Inputs — distributes paging and background music with the masking signal.
• Third-Octave Band EQ — adjustable equalization for masking and audio inputs on each zone.
• Fire Alarm Integration — contact closure mutes the system during alarm events.
• Scheduling and Auto-Ramping — event scheduling and gradual level transitions with 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.

Typical Applications

• Open offices — uniform zoned masking across large floor plates with integrated paging.
• Private offices and conference rooms — per-zone levels protect confidential discussions.
• Healthcare facilities — supports speech privacy in exam rooms, waiting areas, and clinical corridors.
• Call centers — reduces distraction between densely packed agent positions.
• Financial and legal offices — maintains client confidentiality across multi-room suites.

FAQ

How is the Qt X 800D powered?
It is powered over PoE+ from a network switch, with an optional 48 VDC input as an alternative, which keeps plenum installations simple.

Can the Qt X 800D be installed above the ceiling?
Yes. It meets UL 2043 requirements for installation in air handling spaces and ships with a plenum mount bracket; optional wall and rack mount brackets are available.

Does it support paging and background music?
Yes. Two auxiliary inputs distribute paging and music, with independent level and spectrum adjustment per zone.

Can multiple Qt X 800D units work together?
Yes. Multiple Qt X controllers can be combined into one system, sharing audio inputs over Dante or AVB and managed centrally through Biamp SageVue.

Is it eligible for government purchasing?
Yes. The Qt X 800D is GSA eligible, TAA compliant, and manufactured in the U.S.A.
