Cambridge Sound Qt® E-P-W-25-4 Active emitters + 4 patch cables for sound masking, paging & music (White) 4 Pack - 911.0900.900

Includes: 4 x 25' patch cables Small and Powerful The Cambridge Qt® E-P-W-25-4 Active Emitter is a top-tier emitter that can do sound masking and play music and paging signals perfectly. This new speaker offers a higher frequency range than previous direct field emitter options and is small, powerful, and barely visible once installed in finished or open structure ceilings. It also provides uniform direct field masking.Uniform Direct Field MaskingTraditional sound masking systems use large loudspeakers, similar in size to paint cans, to bounce sound off the ceiling deck, which then spreads the masking sound throughout an area. However, the Qt Active Emitter is different. It is a small and stylish device that utilizes Cambridge Sound Management's patented direct field Quiet Technology. This technology provides uniform sound masking directly into the workspace, without the need for indirect distribution through the ceiling.Clear, Articulate Paging and Background MusicDirect field technology eliminates the need for indirect distribution through the ceiling, resulting in improved audio clarity for paging and music. Pages emitted directly into the environment are clearer and easier for listeners to understand, and music sounds better because the speaker is facing the listener, rather than being played through a ceiling material. The Qt Active Emitter offers clear, articulate paging and background music.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 Active 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 White 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)
