DPA 4660 Series Heavy Duty Omnidirectional Microphone

Made for situations where you require maximum security and where the visual size of the mic is less important. The d:screet Heavy Duty Mic Series features a stainless steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. d:screet Heavy Duty microphones are a more robust version of the original 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 d:screet 4660 Series (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 d:screet 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.

d:screet 4660 Heavy Duty Miniature Omnidirectional Microphone, Normal SPL

A very flexible and durable miniature microphone, the d:screet 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.

d:screet 4661 Heavy Duty Miniature Omnidirectional Microphone, Loud SPL

Acoustically identical to the d:screet 4060 , this mic is sensitivity adjusted to cope with higher sound pressure levels, which typically occurs when you are close to a sound source or when the microphone must record undisturbed content of high intensity.

The d:screet 4661 Heavy Duty can handle SPL 144 dB peak before clipping, making it one of the best miniatures for use on very loud and powerful instruments like snare drums, guitar, bass, speaker cabinets or other high-SPL sound sources. The heavy-duty cable relief and a thicker cable works well in live environments, which can sometimes be rough.

This mic is available in two colors: black and beige.

d:screet 4671 Heavy Duty Miniature Omnidirectional Microphone, Normal SPL, Presence Boost

The d:screet 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 d:screet 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 d:screet 4671 Heavy Duty is available in two colors: black and beige.

Flexible Adapter System

All of DPA’s microphones can be configured to run easily and effortlessly with a wireless system. We use a unique MicroDot termination on our microphones together with a changeable adapter to ensure secure configuration. All of the adapters we use are original, developed and manufactured by the wireless system brand you use. This ensures that your mic will work consistently with no connection trouble to your system.

The adapters for wireless systems give you flexible, simple and affordable possibilities. You are no longer bound to one wireless system. As circumstances change, you can just switch your adapter, instead of incurring the cost of a completely new microphone. Moreover, when you make the switch, you won’t hear any loss or change in sound quality.

Using an adapter for wireless, our microphones with MicroDot termination are compatible with the professional wireless systems listed below. Many of these brands have several model numbers. To ensure compatibility you should find your particular model number, which in most cases can be found on the transmitter. Other configurations are possible; however, DPA Microphones cannot guarantee full compatibility in these cases.

Wireless brands we work with: Sennheiser, Shure, Sony, Wisycom, Lectrosonics , Zaxcom and many more.

If you prefer to run via a wired system, all of our mics are available with an XLR connector.
