Cambridge Sound Qt® E-A-W-16-4 Standard Emitters, White, 4 pack, with 4 x 16 ft white plenum rated cables - 911.0893.900

  Small and Powerful The Cambridge E-A-W-16-4 Qt® Active Emitter is designed to provide sound masking while maintaining clear reproduction of paging and music signals from a single source. This speaker offers a wider frequency range and higher sound pressure level than previous direct field emitters. It is both powerful and discreet, making it an ideal choice for use in finished or open structure ceilings.Uniform Direct Field MaskingThe Qt Active Emitter is a compact device that uses direct field Quiet Technology to provide consistent sound masking in the workplace, without bulky loudspeakers.Clear, Articulate Paging and Background MusicAnother benefit of direct field technology is improved audio clarity for paging and music. Because pages are being emitted directly into the environment, they’re clearer and easier for listeners to understand. Music sounds better too because the speaker is facing the listener instead of being played through a ceiling material. The Qt Active Emitter is the only sound masking loudspeaker that’s a complete masking, paging, and music solution for office environments.The Favorite Installation Choice of Integrators The Qt Active Emitter uses the same control modules and cabling infrastructure that made QtPro™ the number one sound masking system choice of companies worldwide as well as the favorite installation choice of integrators. As a result, QtPro remains the easiest sound masking system to install and calibrate, regardless of whether the Active Emitter or original Emitter is used—a true plug and play experience with preset sound masking curves designed specifically for each emitter type.  Conference Room Designer Data Sheet Features Includes 4 x 16 ft white plenum rated cablesActive electronics power the speaker Ported enclosure design allows lower frequency extension down to 125 Hz octave band for sound masking and 115 Hz for paging and music 17 dB louder than previous direct field emitter offerings Plenum-rated, UL-listed, and complies with UL 2043 Delivers four uncorrelated audio channels to reduce phasing/comb-filtering Comes standard with a slip-ring mount for acoustical tile mounting Rear DIP switches reduce volume by 4.5 dB in 1.5 dB increments, if needed Compatible with the Qt 300 and Qt 600 control modules Control via web-based management from any device Compatible with DynasoundPro Network System (Specify DS1320) Specifications  Frequency Response 125 Hz - 10,000 Hz Music/Paging Frequency Response 115 Hz - 12,000 Hz (-10 dB) Masking Min - Max SPL 30 dBA to 60 dBA @ 1 meter Music/Paging Max SPL 74 dBA @ 1 meter Nominal Impedance 40,000 Ω Nominal Dispersion 170 degrees conical / half space Connections RJ-45 Channel Selection Four Channel Auto Sequencing and Repeating Selectable Attenuation 0 dB, -1.5 dB, -3 dB, -4.5 dB Cabling Category UTP Cabling (8 conductor) Included Accessories Acoustic Ceiling Tile Mounting Ring Loudspeaker Type Active w/ Integral Amplifier Maximum Power Consumption 2 watts Operating Voltage 36 VDC Enclosure Front Vented Color Black Certifications UL 2043 Driver Diameter 1.25" (31.75 mm) Dimensions (H x Dia) 3.5" (88.9 mm) x 3.25" (82.55 mm) Net Weight 0.41 lbs (6.5 oz)
