Cambridge Sound Qt X 805D 8-zone sound masking control module - 911.0220.900

Product Overview

The Cambridge Sound Qt X 805D (part number 911.0220.900) is an 8-zone sound masking control module that combines a masking generator, controller, third-octave band equalizer, and amplifier in a single chassis. It supports Dante and AVB media networking, making it suited to networked Qt X deployments across larger facilities. Each of its eight amplified outputs is matched with a pre-amp output and carries its own non-correlated masking source. The module is GSA eligible, TAA compliant, and manufactured in the U.S.A.

Product Description

The Qt X 805D drives sound masking emitters and loudspeakers in direct-field installations, indirect (in-plenum) installations, or a combination of both, and is compatible with DynasoundPro loudspeakers. Two auxiliary audio inputs accept feeds from paging controllers and background music players, and each of the eight amplified outputs has independent adjustments for masking and auxiliary audio levels and spectra. When multiple Qt X controllers are deployed in one system, audio inputs can be shared across all controllers over the AVB or Dante network. The unit integrates with Biamp's SageVue system management software and exposes a third-party control API over Ethernet through dual network ports (media and control). Scheduling features include auto ramping, event scheduling, and a built-in clock with NTP support, while a contact closure input ties the system to fire alarm muting. A front-panel LCD provides local control, with a software-controlled panel lock for security, and a rack mount bracket is included (optional wall mount bracket available). The module is CE marked, ETL listed, RoHS compliant, and covered by Biamp's five-year warranty. Browse the full Cambridge Sound collection for compatible emitters and accessories.

Key Features

• Eight Amplified Zones — supports up to eight zones of amplified speakers matched with eight zones of pre-amp outputs for granular coverage control.
• Dante and AVB Networking — shares audio inputs across multiple Qt X controllers in larger networked systems.
• Eight Non-Correlated Masking Sources — one independent masking generator per output reduces phasing artifacts across the space.
• Two Auxiliary Audio Inputs — distributes paging and background music alongside masking.
• Per-Zone Equalization — third-octave band EQ with independent level and spectrum adjustment for masking and aux audio on each output.
• Direct-Field and In-Plenum Support — drives emitters in direct-field, indirect, or mixed installations.
• Fire Alarm Integration — contact closure input mutes the system during alarm events.
• Scheduling and Auto Ramping — event scheduling and gradual level changes with built-in NTP-synced clock.
• SageVue Compatible — managed through Biamp's SageVue software with a third-party control API over Ethernet.
• Government Procurement Ready — GSA eligible, TAA compliant, and manufactured in the U.S.A.
• Five-Year Warranty — covered by Biamp Systems' five-year warranty; CE marked, ETL listed, RoHS compliant.

Typical Applications

• Open offices — zoned masking across large floor plates with paging and music distribution.
• Private offices and conference rooms — independent zone levels protect confidential conversations.
• Healthcare facilities — supports patient privacy in exam areas, waiting rooms, and nurse stations.
• Call centers — reduces speech distraction between adjacent agent positions.
• Financial and legal offices — keeps client discussions confidential in multi-room suites.

FAQ

What is the difference between the Qt X 805D and the Qt X 800D?
Both are 8-zone Dante/AVB control modules. The 805D pairs each of its eight amplified outputs with a matching pre-amp output, giving installers additional signal routing flexibility; the 800D adds PoE+ powering and plenum mounting.

Can the Qt X 805D handle paging and background music?
Yes. Two auxiliary audio inputs accept paging controller and music feeds, with independent level and spectrum adjustment per output zone.

Does it work in both ceiling-tile and open-plenum installations?
Yes. The module drives emitters in direct-field installations, indirect (in-plenum) installations, or a combination of both, and is compatible with DynasoundPro loudspeakers.

Can it scale to larger campuses?
Yes. Multiple Qt X controllers can be combined into a single system, with audio inputs shared across all controllers over Dante or AVB, all managed through Biamp's SageVue software.

Is the Qt X 805D suitable for government projects?
Yes. It is GSA eligible, TAA compliant, and manufactured in the U.S.A.
