Cambridge Sound PS-AE-3 Active Emitter Power Supply - 330.0050.900

Product Overview

The Cambridge Sound PS-AE-3 (part number 330.0050.900) is an external power supply that provides DC power to Qt Active Emitters through the Active Emitter Power Injector. It offers three 14/2 conductor cabling outputs, each capable of powering up to 50 Qt Active Emitters. A single PS-AE-3 therefore supports a maximum of 150 active emitters, making it the central power source for medium and large direct-field sound masking deployments.

Product Description

Qt Active Emitters contain their own amplification electronics and require DC power in addition to the audio signal from the Qt control module. The PS-AE-3 supplies that power, feeding the system through the Active Emitter Power Injector so the audio cabling infrastructure remains unchanged. Its three independent 14/2 conductor outputs each carry power for up to 50 active emitters, which lets installers split a 150-emitter system into three balanced power runs across a floor plate. Sizing is straightforward: count the active emitters in the design, divide across the three outputs, and confirm no output exceeds 50 emitters. Because the supply is external to the control module, it can be located in the equipment area alongside the Qt controller and injector. The PS-AE-3 is a required accessory whenever Qt Active Emitters — including paging- and music-capable E-P series packs — are deployed.

Key Features

• Powers Up to 150 Active Emitters — three outputs at up to 50 emitters each cover large floor plates from one supply.
• Three 14/2 Conductor Outputs — independent power runs simplify balanced cable layout across zones.
• Works with the Active Emitter Power Injector — delivers DC power without altering the Qt audio cabling.
• Required for Qt Active Emitters — supplies the DC power active emitters need for their integral amplifiers.
• Equipment-Room Friendly — external design installs alongside the Qt control module and injector.

Typical Applications

• Open offices — central power for active emitter arrays across large floor plates.
• Call centers — supports high-density active emitter layouts with paging.
• Healthcare facilities — powers masking systems protecting patient speech privacy.
• Law and financial offices — part of complete masking systems for confidential workspaces.
• Conference room clusters — powers emitters serving meeting room corridors and suites.

FAQ

Do I need the PS-AE-3 for every active emitter system?
Yes. Qt Active Emitters require external DC power for their integral amplifiers, delivered by the PS-AE-3 through the Active Emitter Power Injector.

How many emitters can one PS-AE-3 power?
Up to 150 total — each of its three 14/2 conductor outputs powers as many as 50 Qt Active Emitters.

Does it also work with standard Qt emitters?
Standard (passive) Qt emitters are powered by the control module and do not need this supply; the PS-AE-3 is specific to active emitters.

What else do I need besides the power supply?
An Active Emitter Power Injector, a Qt control module, and the emitter packs themselves; 14/2 conductor cabling carries power to the emitter runs.
