The DPA 4661 CORE+ Lavalier Microphone is made for situations where you require maximum security and where the visual size of the mic is less important. The Heavy Duty 4661 features a stainless steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. DPA's Heavy Duty microphones are a more robust version of the original mics they are based upon.
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.
