DPA 4671 CORE Heavy Duty Omnidirectional Microphone,Presense Boost, Loud SPL, Black, MicroDot (4671-OC-H-B00)
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.
The 4671 Heavy Duty is available in black only.
Features
- The most rugged and reliable version of DPA miniatures
- Stainless steel housing, heavy-duty strain relief and thick cable
- Exceptional audio quality
- Uniform, consistent sound between DPA mics
- Sturdy but small for flexible and easy concealment
- Modular adapter system fits most professional wireless systems
Description
Made for situations where you require maximum security and where the visual size of the mic is less important. The Heavy Duty Mic Series features a stainless steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. Our Heavy Duty microphones are a more robust version of the original lavalier mics they are based upon.
These microphones 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 the everyday use in harsh environments. A 5.4 mm diameter pre-polarized condenser element with a contained within a vertical diaphragm called the Double Vent Protection System, which makes the mics extremely resistant to humidity and sweat.
The acoustic response of the these mics (both the normal and heavy duty version) can be modified by selecting the correct grid for the job. Two grids are supplied with each microphone (not the 4671). The Soft Boost Grid gives a 3 dB soft boost at 8-20 kHz while the High Boost Grid introduces a 10 dB soft boost around 12 kHz. Both of these grids are made of anodized stainless steel. They can be detached from the microphone and wiped cleaned of sweat, makeup, dust etc.
Academy-honored miniatures
In 2021, the Academy of Motion Picture Arts and Sciences’ Board of Governors bestowed a Technical Achievement Award to DPA miniature microphones. The award is directed specifically to Jens-Jørn Stokholm and Ole Moesmann for the innovative development of high-performance miniature and subminiature DPA lavalier microphones.
