Cambridge Sound DS1320-B-4 Dynasound Active Emitter, 4 Pack, Cables not included (Black) - 911.0806.900

Product Overview

The Cambridge Sound DS1320-B-4 is a four-pack of Dynasound Qt Active Emitters in black, part number 911.0806.900, built for direct-field sound masking, paging, and background music from a single ceiling-mounted speaker. 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. The pack is plenum-rated, UL-listed to UL 2043, and ships with slip-ring mounts for acoustical tile installation. Cables are not included and must be ordered separately.

Product Description

The DS1320 Active Emitter delivers 17 dB more output than previous direct-field emitter generations, which lets designers cover the same floor area with consistent masking while keeping headroom for clear paging and music playback. Output reaches 74 dB SPL at 1 meter. Each unit reproduces four uncorrelated audio channels, reducing the phasing and comb-filtering artifacts that degrade masking uniformity in open ceilings. 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. Power requires a 600-watt 3-zone power supply and power injector accessories. Cambridge backs the Active Emitter with a 5-year warranty. Pair this pack with plenum-rated cables and controllers from the Cambridge Sound collection at Creation Networks.

Key Features

• Three Functions, One Speaker — handles sound masking, paging, and background music from a single direct-field emitter.
• Extended Low-Frequency Response — ported enclosure reaches the 125 Hz octave band for masking and 115 Hz for paging and music.
• 17 dB Higher Output — louder than previous direct-field emitters, with 74 dB SPL at 1 meter for clear paging.
• Four Uncorrelated Channels — reduces phasing and comb-filtering for more uniform masking coverage.
• Plenum-Rated and UL-Listed — complies with UL 2043 for open-ceiling and plenum installations.
• DIP-Switch Attenuation — rear switches cut volume up to 4.5 dB in 1.5 dB steps for zone tuning.
• Qt 300 / Qt 600 Compatible — drops into existing QtPro control and cabling infrastructure with web-based management.
• Slip-Ring Mount Included — standard mount for fast acoustical ceiling tile installation.

Typical Applications

The DS1320-B-4 suits open-plan offices, conference room clusters, healthcare facilities protecting patient speech privacy, law firms, and call centers. The black finish blends into open-structure ceilings and dark architectural plenums where white emitters would stand out. Because the same emitter handles masking, paging, and music, integrators can consolidate three overhead systems into one cable plant.

Frequently Asked Questions

Are cables included with the DS1320-B-4?

No. This pack contains four black Active Emitters only. Plenum-rated cables, the 600 W 3-zone power supply, and power injectors are ordered separately.

Which controllers work with the DS1320 Active Emitter?

It is compatible with the Cambridge Sound Qt 300 and Qt 600 control modules and with the DynasoundPro Network System when specified as DS1320.

Can Active Emitters and original Qt Emitters run on the same system?

Yes, both can run on the same control processor simultaneously, provided they are assigned to separate zones.

Is this emitter suitable for open-ceiling installations?

Yes. It is plenum-rated, UL 2043 compliant, and the black housing is designed to disappear visually in open-structure ceilings.

What warranty does Cambridge Sound provide?

The Qt Active Emitter carries a 5-year manufacturer warranty.
