DPA 4661-OP-H-F90 Microphone

DPA 4661-OP-H-F90 CORE+ Heavy Duty Miniature Microphone (Loud SPL, MicroLock, Beige)

The DPA 4661-OP-H-F90 is the most durable and technologically advanced version of a miniature microphone in the DPA range. This model combines the latest CORE+ technology with an extremely robust (heavy-duty) construction and the most secure MicroLock connector. The microphone is designed for extreme usage conditions – reality shows, sports broadcasts, or intensive theatrical work, where equipment is subjected to significant mechanical stress, but sound quality cannot be compromised.

The microphone features a stainless steel housing and a thicker, 2.2 mm cable with reinforced strain relief. The Beige color allows it to be easily concealed. The new CORE+ technology ensures even lower distortion than the standard CORE version, and the Loud SPL capsule handles loud vocals perfectly (up to 144 dB). The MicroLock connector guarantees that the cable will never accidentally disconnect, while maintaining compatibility with the MicroDot ecosystem.
