DPA CORE+ 4671 Heavy Duty Omni Mic, Presence Boost, Loud SPL, MicroLock (4671-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 4671 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.

The 4671 is a fantastic lavalier mic, which features a presence boost of typically 5 dB at 4 to 6 kHz, which is optimized for chest-placement. The mic has a boost that maximizes speech intelligibility. This microphone will be able to handle sound pressure levels up to 144 dB before clipping occurs.

An acoustical low-cut at 100 Hz has been incorporated in the 4071’s capsule so the built-in preamplifier (and the wireless system) don’t need to cope with unwanted sound.  Furthermore, the low-cut filter removes low-frequency rumble and noise. A miniature mesh and a fur windscreen are optional items for this microphone.
