DPA 4071-OP-C-B90 CORE+ Omnidirectional Lavalier Microphone (Loud SPL, Presence Boost)

The DPA 4071-OP-C-B90 is a professional miniature lavalier microphone, part of the advanced CORE+ series. This model is specially calibrated for use with Loud SPL (high sound pressure) sources and features an integrated Presence Boost (approximately 5 dB lift in the 4–6 kHz range), ensuring maximum speech clarity and articulation even when the microphone is hidden under clothing.

Utilizing CORE+ by DPA technology, it achieves exceptionally clean sound with minimal distortion and a wide 111 dB dynamic range. The microphone has an IP58 certification, providing exceptional resistance to moisture, sweat, and dust. The black body and a capsule diameter of just 5.4 mm ensure discretion, while the MicroLock connector guarantees secure fastening in the most demanding working conditions.
