It pairs one Qt X 300 three-zone controller with a single E-P-W-16-4 pack, for four white Qt Active Emitters with 16 ft patch cables. Direct-field emitters raise the background sound level just enough to make nearby conversations unintelligible, while the same emitters carry announcements and music. Actual coverage depends on ceiling height and layout, and the Qt X 300 scales to 36,000 sq ft as you add emitters — so this entry point grows into a full multi-zone system without replacing the controller.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e1 x \u003ca href=\"https:\/\/creationnetworks.net\/products\/cambridge-qt-x-300-control-module-sound-masking-generator-and-controller\"\u003eCambridge Sound Qt X 300\u003c\/a\u003e\u003c\/b\u003e 3-zone sound masking controller (911.0078.900)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e1 x \u003ca href=\"https:\/\/creationnetworks.net\/products\/biamp-cambridge-qt%C2%AE-e-p-w-16-4-active-emitters-for-sound-masking-paging-music-white-4-pack-0899-900\"\u003eCambridge Sound Qt E-P-W-16-4\u003c\/a\u003e\u003c\/b\u003e Active Emitter 4-pack, white, with 4 x 16 ft patch cables (911.0899.900) — 4 emitters total\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eRequired, sold separately:\u003c\/b\u003e Qt Active Emitters are powered through a \u003ca href=\"https:\/\/creationnetworks.net\/products\/cambridge-active-emitter-power-supply\"\u003eCambridge PS-AE-3 Active Emitter Power Supply\u003c\/a\u003e and a PI-AE power injector installed next to the first emitter on the run.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/products\/cambridge-sound-qt-x-300-control-module-sound-masking-generator-and-controller-911-0078-900-creation-networks-70213.png?v=1757889625\" alt=\"Cambridge Qt X 300 sound masking controller for the 400 sq ft starter kit\" loading=\"lazy\" style=\"max-width:100%;height:auto;display:block;margin:16px auto\"\u003e\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe Qt X 300 is a compact, networked sound masking controller with three controllable outputs, each with A and B cable runs, supporting up to 50 Qt Active Emitters per run. Even in this smallest configuration, each output can be set to its own masking level, paging and music level, and spectrum — useful if a single small suite still has more than one distinct area, such as a reception nook and a private office. Two analog inputs bring in a paging source and a background music player, and the AVB network port lets multiple Qt X controllers share audio if the deployment grows into a larger commercial sound masking installation later. The Qt Active Emitters are direct-field ceiling emitters: the driver faces the room, so masking spreads evenly and paging stays intelligible. Each emitter produces 30 to 60 dBA of masking and up to 74 dBA of paging or music at 1 meter. Emitters daisy-chain over Category UTP cable with RJ-45 connectors, and rear switches trim level in 1.5 dB steps for fine tuning during commissioning.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhy \"active\" matters:\u003c\/b\u003e Cambridge's Qt Active Emitters are the powered version of the company's direct-field emitter line — each unit has its own integral amplifier, rather than relying only on the controller's output like the original passive Qt Emitter. Per Cambridge's own spec sheet, that integral amplifier delivers 17 dB more output than the original passive design. Masking level is unaffected either way (both stay in the same 30–60 dBA comfort range), but that extra headroom is exactly what lets a single ceiling emitter double as a paging and music speaker rather than a masking-only device — announcements and background music play back clearly at up to 74 dBA, a level a passive emitter isn't built to reach. The tradeoff is that active emitters need their own low-voltage power, which is why the PS-AE-3 supply and PI-AE injector are called out above as required, sold separately.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/cambridge-sound-qt-r-e-p-w-16-4-active-emitters-4-patch-cables-for-sound-masking-paging-and-music-white-4-pack-911-0899-900-creation-networks-75058.jpg?v=1757896302\" alt=\"Cambridge Qt E-P-W-16-4 white active emitter 4-pack with patch cables\" loading=\"lazy\" style=\"max-width:100%;height:auto;display:block;margin:16px auto\"\u003e\u003c\/p\u003e\u003cp\u003eCreation Networks offers eight Qt Active Emitter kits built around the same emitter pack.

Final emitter spacing depends on ceiling height, ceiling type, and room layout, and more emitters can be added to the same Qt X 300 controller for larger spaces.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIs this a scaled-down controller, or the same one used in the larger kits?\u003c\/b\u003e\u003cbr\u003eIt's the identical Qt X 300 controller used in the 800 and 1,600 sq ft kits — nothing is downgraded. Starting here means the controller itself can grow with the space; only emitter packs need to be added later.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat does \"active\" mean on these emitters, and why does it matter?\u003c\/b\u003e\u003cbr\u003eActive emitters have their own integral amplifier rather than depending only on the controller for output. Cambridge's own spec sheet documents 17 dB more output than the original passive Qt Emitter design — that headroom is what allows the same ceiling emitter to reproduce paging and music clearly (up to 74 dBA) rather than being limited to masking noise alone.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat else do I need to power the Qt Active Emitters?\u003c\/b\u003e\u003cbr\u003eActive emitters need a PS-AE-3 power supply and a PI-AE power injector installed next to the first emitter on the run. One PI-AE has two channels, each powering up to 25 active emitters, and one PS-AE-3 feeds up to three injectors.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat is this kit compatible with?\u003c\/b\u003e\u003cbr\u003eThe Qt X 300 drives Qt standard or Qt Active Emitters and shares audio with other Qt X controllers over AVB. Additional emitters, paging stations, and accessories are available in the \u003ca href=\"https:\/\/creationnetworks.net\/collections\/cambridge-sound\"\u003eCambridge Sound collection\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCan this system handle paging and background music?\u003c\/b\u003e\u003cbr\u003eYes. The two analog inputs on the Qt X 300 accept a paging source and a music player, and the same active emitters reproduce both alongside the masking signal.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCan I expand the system later?\u003c\/b\u003e\u003cbr\u003eYes. The Qt X 300 supports up to 36,000 sq ft across three outputs, so you can add E-P-W emitter packs and power injectors as the space grows — this is a genuine starting point, not a kit you'll outgrow and replace.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat warranty and support are included?\u003c\/b\u003e\u003cbr\u003eThe Qt X 300 and Qt Active Emitters carry Biamp's five-year warranty.
