Product overview
The DPA 4166 CORE+ combines the sound of the 4066 omnidirectional capsule with a lightweight and flexible system, available as a single-ear earset or a two-ear headset, with clean and transparent sound and a lot of headroom.
It offers clear, natural voice intelligibility and extremely high SPL capabilities, so users can both speak and sing into the microphone with no hint of distortion. The capsule is the same type as on the 4066, attached to an interchangeable boom arm.
The earset is the quickest to put on and often the best choice when miking needs to be fast and easy, for example for conference use. It is ergonomically designed to fit comfortably, adjusts to any ear size and head shape, mounts securely and is hardly visible. Boom and ear hook rotate, so the microphone can be used on either the left or the right ear. The headset version, worn on both ears, is the comfortable and most secure option.
A connector splits the cable from the microphone boom, so broken cables and wireless connectors can be swapped quickly. CORE+ neutralises distortion across the entire dynamic range, and the MicroLock connector is a dependable, secure locking connector; the 4166 CORE+ is also offered terminated in 3-pin LEMO, TA4F Mini-XLR or Mini-Jack, in black, brown or beige, with a 110 mm or 90 mm boom.
