DPA CORE+ 4660 Heavy Duty Omni Mic, Normal SPL, MicroLock (4660-OP-H-B90)

Made for situations where you require maximum security and where the visual size of the mic is less important. The Heavy Duty DPA 4660 features a stainless steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. The DPA Heavy Duty microphones are a more robust version of the original mics they are based upon.

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.

A very flexible and durable miniature microphone, the 4660 Heavy Duty exhibits an exceptionally accurate omnidirectional pattern and therefore does not need to be aimed directly at the sound source to achieve quality pickup. It is especially suited for capturing speech in all of its nuances and can be used for very high-end ambient recordings where space is limited or the microphone needs to be hidden.. This microphone handles sound pressure levels up to 134 dB before clipping occurs.

This mic is available in two colors: black and beige (the black variant is also available with 3-pin LEMO connector).
