The DPA 4066 CORE+ Headset Microphone offers clean and transparent sound quality with lots of headroom. For years, this has been the chosen headset mic for broadcasters as well as theaters on Broadway, as well as in many auditorium and lecture halls. This is due to its pristine sound and durability. What is CORE+ Technology? CORE+ neutralizes distortion across the entire dynamic range of the microphone, making any residual noise imperceptible and virtually unmeasurable. This new technology provides a new level of pure, clean audio for an extraordinary sound experience, whether recording or amplifying content. DPA's CORE+ technology also reduces the hassle of unpredictable challenges of live sound environments, such as when the talent speaks or sings at louder volumes or on stages with multiple microphones. Microphones with CORE+ completely eliminate artifacts, while enhancing the transparency of the entire sound image, to provide audio professionals more freedom to create their desired soundscape.
