The DPA Microphones 4671 Heavy Duty Miniature Omnidirectional Microphone, Normal SPL, is a lavalier mic that 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 and 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 wireless system don’t need to cope with unwanted sound. Furthermore, the low-cut filter removes low-frequency rumble and noise.

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

These microphones can withstand the toughest of conditions. They are designed with an extra-robust, Kevlar-reinforced cable and a strain relief, which is built to withstand the constant twists, bends and pulls that are part of everyday use in harsh environments. A 5.4 mm diameter pre-polarized condenser element contained within a vertical diaphragm called the Double Vent Protection System makes the mics extremely resistant to humidity and sweat.
