The 4466 CORE+ omni mic offers clean and transparent sound quality with lots of headroom. The microphone’s sensitivity is 6 mV/Pa. This matches the level of the human voice to the general input sensitivity of most wireless transmitters.
When powered correctly, the microphone will be able to handle very high sound pressure levels up to 134 dB SPL so users can both speak and sing into the mic with no hint of distortion. The max SPL handling is an impressive 144 dB.
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.
