DPA 4671 CORE Heavy Duty Omni Lavalier Microphone, Presence Boost

Product overview

The DPA 4671 CORE Heavy Duty is an omnidirectional miniature lavalier microphone with a presence boost, optimised as a chest-placed microphone for broadcast, ENG and film.

Its presence boost of typically 5 dB at 4 to 6 kHz is optimised for chest placement and maximises speech intelligibility. An acoustical low-cut at 100 Hz is incorporated in the capsule, so the built-in preamplifier and the wireless system do not need to cope with unwanted sound, and low-frequency rumble and noise are removed. The microphone handles sound pressure levels up to 144 dB before clipping.

The Heavy Duty series is a more robust version of the original DPA miniatures it is based on: a stainless steel housing, a heavy-duty, aramid-reinforced cable relief and a thick 2.2 mm cable withstand the constant twists, bends and pulls of everyday use in harsh environments. The 5.4 mm pre-polarised condenser element with the Double Vent Protection System makes the microphone extremely resistant to humidity and sweat.

This is the CORE generation of the 4671 Heavy Duty, fitted with the MicroDot connector for DPA's modular adapter system, which fits most professional wireless systems. Available in black.

Presence boost for chest placement

When a microphone is placed on the chest, the boost of typically 5 dB at 4 to 6 kHz maximises speech intelligibility, and the acoustical low-cut at 100 Hz keeps low-frequency rumble and noise away from the preamplifier and the wireless system.
