Cambridge Sound Qt X 600 + 12x Active Emitter (E-P-W-16-4) Kit, 2-Zone Configuration – 4,800 SF Sound Masking, Paging & Music (TAA)

Product Overview

This Cambridge Qt X 600 kit is sized for a large single-floor deployment of up to about 4,800 sq ft, configured around two zones rather than the controller's full six. It pairs one Qt X 600 controller with twelve E-P-W-16-4 packs, for forty-eight white Qt Active Emitters with 16 ft patch cables. This configuration suits a building with two genuinely distinct large areas — a big open floor plus a separate department, for example — rather than a space that needs six independently tuned zones. Because it's built on the same Qt X 600 hardware as the 2,400 sq ft kit, four more zones remain available if the floor plan ends up needing finer zoning later. Actual coverage depends on ceiling height and layout.

What's Included

• 1 x Cambridge Sound Qt X 600 6-zone sound masking controller (911.0069.900), configured for 2 active zones in this kit
• 12 x Cambridge Sound Qt E-P-W-16-4 Active Emitter 4-packs, white, each with 4 x 16 ft patch cables (911.0899.900) — 48 emitters total

Required, sold separately: Qt Active Emitters are powered through Cambridge PS-AE-3 Active Emitter Power Supplies and PI-AE power injectors installed next to the first emitter on each run — at 48 emitters split across 2 zones (24 emitters per zone), plan on multiple PI-AE injectors per zone since each PI-AE channel supports up to 25 active emitters.

Product Description

The Qt X 600 is a compact, networked sound masking controller with six controllable outputs, each with A and B cable runs, supporting up to 50 Qt Active Emitters per run — meaning a single output alone can drive up to 100 emitters. This kit deliberately uses only 2 of the 6 available outputs, splitting the 48 emitters roughly 24 per zone, well within each output's capacity. That leaves 4 zones unused and available if a future renovation splits the floor into more distinct areas; nothing about the hardware needs to change, only cabling and emitter assignment. Two analog inputs bring in a paging source and a background music player per zone, and the AVB network port lets multiple Qt X controllers share audio if the deployment spans more than one building or floor. The Qt Active Emitters are direct-field ceiling emitters: the driver faces the room, so masking spreads evenly and paging stays intelligible even across a large open floor. Each emitter produces 30 to 60 dBA of masking and up to 74 dBA of paging or music at 1 meter.

Why "active" matters: 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. The tradeoff is that active emitters need their own low-voltage power, which is why the PS-AE-3 supplies and PI-AE injectors are called out above as required, sold separately.

Creation Networks offers several Qt Active Emitter kits built around the same emitter pack. Choose by coverage area and zoning:

*Coverage estimates assume roughly 100 sq ft per emitter; actual layout depends on ceiling height and type.

Key Features

• Sized for About 4,800 sq ft — Forty-eight active emitters cover a large single floor or two big departments.
• Built for Two Large Zones — Configured around 2 outputs rather than the controller's full 6, matched to floor plans with two genuinely distinct areas instead of many small ones.
• Four Zones Held in Reserve — The same Qt X 600 hardware has 4 more outputs available if the space is later subdivided — no controller swap required.
• Masking, Paging, and Music — One ceiling emitter network carries speech privacy masking, overhead paging, and background music.
• Active, Amplified Emitters — Integral amplifiers deliver 17 dB more output than Cambridge's original passive Qt Emitter, the headroom that makes paging and music intelligible from the ceiling.
• Expandable to 72,000 sq ft — Add E-P-W emitter packs and activate additional zones on the same Qt X 600 as the facility grows.
• Networked Management — AVB networking lets multiple Qt X controllers share audio across larger deployments.
• Plenum-Rated Emitters — Emitters are ETL listed and evaluated to UL 2043 for installation in air handling spaces.
• Five-Year Warranty — Both the Qt X 600 and the Qt Active Emitters are covered by Biamp's five-year warranty.

Typical Applications

• Large open-plan corporate floor
• Two-department building (e.g., call center plus back office)
• Commercial meeting space
• Government space
• Multi-purpose room

Frequently Asked Questions

Why only 2 zones on a 6-zone controller?
This kit is sized for floor plans with two genuinely distinct large areas rather than many small ones. Using 2 outputs at higher emitter counts per zone keeps commissioning simpler while still leaving 4 zones in reserve on the same hardware if the space is subdivided later.

Can I activate more zones later?
Yes. The Qt X 600 in this kit is the identical 6-zone controller used in the 2,400 sq ft kit — nothing is disabled in hardware. Additional zones just need emitter packs assigned and wired to the unused outputs.

What does "active" mean on these emitters, and why does it matter?
Active 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.

What else do I need to power 48 active emitters?
Each PI-AE power injector channel supports up to 25 active emitters, so 48 emitters across 2 zones will need multiple PI-AE units and PS-AE-3 supplies — plan power infrastructure per zone during design.

Can this system handle paging and background music?
Yes. Each active zone's analog inputs accept a paging source and a music player, and the same active emitters reproduce both alongside the masking signal.

What warranty and support are included?
The Qt X 600 and Qt Active Emitters carry Biamp's five-year warranty. Creation Networks provides sound masking design, installation, commissioning, and ongoing support nationwide.
