DPA 4466-OP-R-F90 – CORE+ Omnidirectional Headset Microphone with Refine Headset, MicroLock Connector, Beige Version

The DPA 4466-OP-R-F90 is a premium omnidirectional headset microphone featuring DPA’s renowned 5 mm CORE capsule, combined with the new ultra-thin Refine headset. Designed for environments requiring high-fidelity vocal reproduction — theatre, broadcast, high-end conferencing, houses of worship, and live performances — it delivers a transparent, natural and highly versatile sound.

Thanks to its omnidirectional pickup pattern, the 4466 captures voice with exceptional openness and consistency, even during head movement. Its 6 mV/Pa sensitivity and 111 dB dynamic range ensure outstanding speech intelligibility, while its ability to handle up to 144 dB SPL prevents distortion in the most demanding vocal applications.

This Loud SPL version is optimized to deliver an extended dynamic margin and clear, undistorted reproduction in high-SPL environments. Certified IP58, it offers advanced resistance to moisture, sweat and dust, ensuring long-term reliability on stage or outdoors.

The Refine headset marks a major leap in ergonomics: one-size-fits-all design, ultra-thin stainless-steel frame, 3-point support system (above, below and behind the ear), rapid adjustments and a dual-axis boom design for perfect placement without bending. The 90° cable management system ensures total visibility control on stage or on camera.

Its matte non-reflective PVD finish provides discretion and impressive durability. The MicroLock connector ensures secure attachment and full compatibility with DPA DAD9000-series adapters for professional wireless systems (not included).
