The 4466 CORE+ Omnidirectional Headset Microphone combines DPA’s renowned 5 mm capsules with CORE+ by DPA technology and the Red Dot award-winning headset. These are the most advanced headsets – secure, durable and flexible – for segments including: Theatre, Broadcast, House of Worship and Conferencing.
CORE+ takes your miniature mic to the next level, neutralizing distortion across the entire dynamic range. MicroLock – A dependable, secure locking microphone connector with limitless flexibility and reassuring reliability.
This 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.
The DPA 4466 is also available with 3-pin LEMO, TA4F Mini-XLR, or Mini-Jack connector - all variants come in either black, brown, or beige.
