Cambridge Sound E-A-B-16-4 Standard Emitters, Black, 4 pack, with 4 x 16 ft black plenum rated cables - 911.0889.900

  Small and Powerful The new Cambridge Sound E-A-B-16-4 Standard Emitter is a single-source Emitter capable of both sound masking and simultaneous clear reproduction of paging and music signals. It provides higher SPL and a broader frequency range than previous direct field Emitter offerings in a small, powerful, virtually invisible speaker once deployed in finished or open structure ceilings.Uniform Direct Field MaskingSound masking systems have traditionally used large loudspeakers, similar in size to paint cans, to create sound that reverberates off the ceiling deck. This method indirectly distributes the masking sound throughout the environment. However, the Qt Active Emitter is a small and sleek device that uses Cambridge Sound Management's patented direct field Quiet Technology to provide even sound masking directly into the workspace.Clear, Articulate Paging and Background MusicDirect field technology has the advantage of enhancing audio clarity for paging and music. With direct emission of pages into the environment, listeners can better understand what is being said. Additionally, music sounds superior because the speaker is aimed towards the listener instead of playing through a ceiling material. For office settings, the Qt Active Emitter is the sole sound masking loudspeaker that provides a comprehensive solution for masking, paging, and music needs.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 black 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)
