Each emitter is a compact ceiling loudspeaker that masks sound while simultaneously delivering clear paging and music signals from a single source. The active design offers a wider frequency range and higher SPL than previous direct-field emitters — 17 dB louder — and is virtually invisible once installed in finished or open-structure ceilings. The emitters are plenum-rated, UL-listed, and comply with UL 2043.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the DS1320 is the DynasoundPro-network version of the Qt Active Emitter. Active electronics power the speaker, and a ported enclosure extends sound masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with output of 74 dB SPL at 1 meter. Four uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters, producing the uniform masking field that makes the system comfortable to occupy. The emitters use the same control modules, cabling infrastructure, and driver size as other Cambridge Sound systems, are compatible with the Qt 300 and Qt 600 control modules, and can run alongside original Qt Emitters on the same processor when assigned to separate zones. Powering the active emitters requires the 600-watt 3-zone power supply and power injector accessories. A slip-ring mount for acoustical tile installation comes standard, rear DIP switches trim level in 1.5 dB increments down to -4.5 dB, and the system is managed through web-based control from any device. The DS1320 carries a five-year warranty.

Each emitter carries active electronics and a ported enclosure that extends low-frequency output to the 125 Hz octave band for masking and 115 Hz for paging and music.

Rear DIP switches trim volume in 1.5 dB increments up to -4.5 dB for fine zone balancing. The emitters work with Cambridge Sound Qt 300 and Qt 600 control modules and are compatible with the DynasoundPro Network System when specified as DS1320, with web-based management available from any device.

Each single-source emitter delivers sound masking while reproducing clear paging and music signals, with a wider frequency range and higher SPL than previous direct-field emitters. The compact housing is discreet in both finished and open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe Qt Active Emitter uses direct-field Quiet Technology to project consistent masking into the workspace without bulky reverberant loudspeakers. Because pages and music are emitted directly toward listeners rather than through ceiling material, intelligibility and audio quality improve. Masking frequency response covers 125 Hz to 10,000 Hz, with music and paging extending 115 Hz to 12,000 Hz (-10 dB). Masking levels adjust between 30 and 60 dBA at 1 meter, and music\/paging output peaks at 74 dBA. Four uncorrelated auto-sequencing channels suppress phasing and comb-filtering. The emitters run on the same Qt 300 and Qt 600 control modules and category UTP cabling that the QtPro platform is built on, with preset masking curves for plug-and-play calibration. Each active emitter draws a maximum of 2 watts at 36 VDC and carries UL 2043 certification for plenum installation.

Qt emitters are the foundation of the Qt Quiet Technology Sound Masking System, projecting uniform direct-field masking into the workspace from compact ceiling-mounted speakers.

The control module equalizes output to within +\/- 1 dB in 1\/3-octave bands across the entire speech range, so masking sounds consistent as occupants move through the space. Maximum output spans 36 to 57 dB, appropriate for direct-field masking levels in occupied offices. Each emitter presents a 4,000-ohm nominal impedance and connects over plenum-rated CAT3 wiring with RJ-45 connectors, making long daisy-chained runs practical with low-voltage cabling. The included 25-foot white cables suit larger ceiling grids and longer hops between emitters. The units are UL Listed and install into standard acoustical tile with the included slip rings.

The result is a single powered signal line that drives Qt Active Emitters.

It accepts the masking audio output from the QtPro module on one side and DC from the Active Emitter Power Supply on the other, then outputs the combined powered signal downstream. This injection approach keeps emitter wiring simple, since a single run carries everything the active emitters need to operate.

Because it fits both Qt Active and Qt Standard Emitters, one part number covers either system. White is the standard choice for typical office ceilings; the black AE-UB-B is available for dark finishes.

Each emitter handles sound masking and simultaneous, clear reproduction of paging and background music from a single ceiling-mounted source. Active electronics and a ported enclosure deliver 17 dB more output and wider frequency range than previous direct-field emitters. The units are UL 2043 plenum rated and blend into finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the Qt Active Emitter projects masking directly into the workspace rather than bouncing it off the ceiling deck like conventional in-plenum loudspeakers. The result is a more uniform masking field and clearer paging and music, since the speaker faces the listener instead of playing through ceiling material. The ported enclosure extends masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between neighboring emitters. Each emitter connects over RJ-45 category UTP cabling, draws no more than 2 watts at 36 VDC, and includes an acoustic ceiling tile mounting ring with slip-ring mount. Rear DIP switches trim output in 1.5 dB steps to -4.5 dB for room-by-room balancing. The pack is compatible with Qt 300 and Qt 600 control modules and the DynasoundPro network system (specify DS1320).

Each emitter performs sound masking and clear, simultaneous reproduction of paging and background music from a single ceiling-mounted source. Active electronics and a ported enclosure extend frequency range and output beyond previous direct-field emitters. The units are UL 2043 plenum rated and nearly invisible once installed in finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the Qt Active Emitter distributes masking directly into the workspace using Cambridge Sound's patented direct-field Quiet Technology, rather than bouncing sound off the ceiling deck from large in-plenum loudspeakers. The direct path produces a uniform masking field and clearer paging and music, since the driver faces the listener instead of playing through ceiling material. The ported enclosure extends masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter and 17 dB more output than previous direct-field emitters. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each emitter connects over RJ-45 category UTP cabling, draws no more than 2 watts at 36 VDC, and includes an acoustic ceiling tile mounting ring with slip-ring mount. Rear DIP switches trim level in 1.5 dB steps down to -4.5 dB. The pack works with Qt 300 and Qt 600 control modules and is compatible with the DynasoundPro network system (specify DS1320).

Each emitter provides sound masking with clear, simultaneous reproduction of paging and music signals from a single ceiling source. Active electronics and a ported enclosure extend frequency range and output beyond previous direct-field emitters. The units are UL 2043 plenum rated and virtually invisible once installed in finished or open ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the Qt Active Emitter projects masking directly into the workspace using Cambridge Sound's patented direct-field Quiet Technology, rather than bouncing sound off the ceiling deck from bulky in-plenum loudspeakers. The direct path produces an even masking field and clearer paging and music, since the driver faces the listener instead of playing through ceiling material. The ported enclosure extends masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter and 17 dB more output than previous direct-field emitters. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each emitter connects over RJ-45 category UTP cabling, draws no more than 2 watts at 36 VDC, and includes an acoustic ceiling tile mounting ring with slip-ring mount. Rear DIP switches trim level in 1.5 dB steps down to -4.5 dB. The pack works with Qt 300 and Qt 600 control modules and is compatible with the DynasoundPro network system (specify DS1320).

Each emitter is a compact, ported, direct-field loudspeaker with active electronics that delivers 17 dB more output than previous direct-field emitters. The units are plenum rated, UL 2043 compliant, and nearly invisible once installed in finished or open-structure ceilings. They connect over standard category UTP cabling with RJ-45 connections.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eConventional masking systems bounce sound off the ceiling deck from large upward-firing loudspeakers; the Qt Active Emitter instead projects the masking signal directly into the workspace using Cambridge Sound's direct-field Quiet Technology, producing uniform coverage without relying on the plenum as a mixing chamber. Direct-field delivery also improves paging intelligibility and music quality, since the driver faces the listener rather than playing through ceiling material — making this the single-source emitter that handles masking, paging, and music together. The ported enclosure extends low-frequency response down to the 125 Hz octave band for masking and 115 Hz for paging and music, with masking output adjustable from 30 to 60 dBA at 1 meter and paging\/music peaks up to 74 dBA. Four uncorrelated audio channels auto-sequence across emitters to reduce phasing and comb-filtering. Rear DIP switches attenuate individual emitters by up to 4.5 dB in 1.5 dB steps, and a slip-ring mount for acoustical tile ceilings is included. The emitters are compatible with Qt 300 and Qt 600 control modules and with the DynasoundPro network system (specify DS1320), using the same cabling infrastructure as the rest of the QtPro platform.

Each emitter combines sound masking with clear, simultaneous reproduction of paging and background music from a single ceiling-mounted source. Active electronics and a ported enclosure extend output 17 dB louder and lower in frequency than previous direct-field emitters. The emitters are UL 2043 plenum rated and nearly invisible once installed in finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the Qt Active Emitter distributes masking directly into the workspace instead of bouncing it off the ceiling deck the way conventional in-plenum loudspeakers do. This direct-field approach produces a more uniform masking level and clearer paging, since pages and music face the listener rather than passing through ceiling material. The ported enclosure extends sound masking response down to the 125 Hz octave band and paging\/music response down to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each unit connects over standard RJ-45 category UTP cabling, draws a maximum of 2 watts at 36 VDC, and includes an acoustic ceiling tile mounting ring with a slip-ring mount. Rear DIP switches trim output in 1.5 dB steps down to -4.5 dB for fine balancing. The emitters work with Qt 300 and Qt 600 control modules and are compatible with the DynasoundPro network system (specify DS1320).

Each emitter performs sound masking and plays paging and music signals with clarity from a single ceiling-mounted source. Advanced direct-field electronics deliver a wider frequency range and higher SPL than previous emitter generations. The units are UL 2043 plenum rated and virtually invisible in finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eEmitters are the ceiling loudspeakers of a sound masking system, and the Qt Active Emitter uses Cambridge Sound's direct-field Quiet Technology to project masking straight into the workspace rather than bouncing it off the ceiling deck from large in-plenum loudspeakers. The direct path yields consistent masking levels between workstations and clearer paging and music, since the driver faces the listener instead of playing through ceiling material. The ported enclosure extends masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter and 17 dB more output than previous direct-field emitters. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each unit connects over RJ-45 category UTP cabling, draws no more than 2 watts at 36 VDC, and ships with an acoustic ceiling tile mounting ring and slip-ring mount. Rear DIP switches trim level in 1.5 dB steps to -4.5 dB. The pack works with Qt 300 and Qt 600 control modules and the DynasoundPro network system (specify DS1320).

Each single-source emitter performs sound masking while simultaneously reproducing clear paging and music signals. The design delivers higher SPL and a broader frequency range than earlier direct-field emitters in a compact housing that virtually disappears in finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eTraditional sound masking relies on large loudspeakers that bounce sound off the ceiling deck, distributing masking indirectly. The Qt Active Emitter instead uses Cambridge Sound Management's patented direct-field Quiet Technology to project even masking straight into the workspace. Direct-field emission also improves paging intelligibility and music quality, since the speaker faces the listener rather than firing through ceiling material. Frequency response runs 125 Hz to 10,000 Hz for masking and 115 Hz to 12,000 Hz (-10 dB) for music and paging, with masking levels adjustable from 30 to 60 dBA and music\/paging output reaching 74 dBA at 1 meter. Each emitter sequences four uncorrelated audio channels to suppress phasing and comb-filtering. The pack uses the same Qt 300 and Qt 600 control modules and category UTP cabling infrastructure as the rest of the QtPro line, with preset masking curves for plug-and-play calibration. Power draw is just 2 watts at 36 VDC, and the front-vented enclosure is UL 2043 certified.

Emitters are the ceiling loudspeakers of a Qt direct-field sound masking system, distributing the masking signal evenly into the workspace below. The 25-foot cable length suits typical runs from emitter to emitter or back to zone cabling in standard ceiling grids. Black housings blend into dark or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eIn a Qt direct-field system, the control module generates the masking signal and the emitters reproduce it facing downward into the occupied space, rather than bouncing sound off the ceiling deck the way conventional in-plenum loudspeakers do. That direct path yields a more uniform masking level across the floor plate with less acoustic variation between workstations. This pack provides four black emitters along with four 25-foot black plenum rated cables, allowing the cabling to run above suspended ceilings and through air handling spaces. Emitter packs like this one are the repeating building block of a deployment: designers lay out emitters on a regular grid and daisy-chain them back to the Qt control module zone outputs. The black finish suits exposed ceilings, dark tile, and open-structure architectural treatments.

Masking response extends down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each emitter connects over RJ-45 category UTP cabling, draws a maximum of 2 watts at 36 VDC, and ships with an acoustic ceiling tile mounting ring and slip-ring mount. Rear DIP switches trim level in 1.5 dB steps down to -4.5 dB. The pack is compatible with Qt 300 and Qt 600 control modules and with the DynasoundPro network system (specify DS1320).

Sound masking adds a low-level, engineered background sound that makes nearby speech unintelligible, improving privacy and reducing distraction. Volume and settings adjust quickly from the module's front panel, and all cabling, mounts, and installation hardware are included.

It includes a front-panel LCD, software panel lock, auto ramping, event scheduling, an adjustable equalizer for masking and audio inputs, and four non-correlated masking sources per zone. A contact closure integrates with fire alarm systems, dual network ports separate media and control, and a web interface plus third-party Ethernet API support remote management. The included Qt emitters are wide-dispersion direct-field loudspeakers with 1.25-inch drivers, smaller than a coffee mug, delivering four uncorrelated audio channels for uniform, unobtrusive masking. Adjustable emitters can be attenuated up to 9 dB in 3 dB steps for spot adjustments or micro zones down to 100 square feet.

Emitters are the ceiling loudspeakers of a Qt direct-field sound masking system, and this model uses active electronics to provide sound masking with clear reproduction of paging and music signals from a single source. It offers a wider frequency range and higher sound pressure level than previous direct-field emitters. The units are UL-listed, comply with UL 2043 for plenum installation, and remain discreet in finished or open-structure ceilings.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe Qt emitter projects masking directly into the workspace using Cambridge Sound's direct-field Quiet Technology, instead of bouncing sound off the ceiling deck from bulky in-plenum loudspeakers. That direct path delivers a uniform masking field and clearer paging and music, because the driver faces the listener rather than playing through ceiling material. The ported enclosure extends masking response down to the 125 Hz octave band and paging\/music response to 115 Hz, with a maximum paging\/music output of 74 dBA at 1 meter and 17 dB more output than previous direct-field emitters. Four auto-sequencing uncorrelated audio channels reduce phasing and comb-filtering between adjacent emitters. Each emitter connects over RJ-45 category UTP cabling, draws a maximum of 2 watts at 36 VDC, and ships with an acoustic ceiling tile mounting ring and slip-ring mount. Rear DIP switches trim level in 1.5 dB steps down to -4.5 dB. The pack is compatible with Qt 300 and Qt 600 control modules and with the DynasoundPro network system (specify DS1320).
