DPA 4660 CORE Heavy Duty Omnidirectional Microphone, Normal SPL
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.
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.
