Acoustically identical to the 4060, the DPA Microphones 4661 CORE Heavy Duty Omni Mic, Loud SPL, 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 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, guitars, 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.

Made for situations where you require maximum security and where the visual size of the mic is less important, the 4661 Heavy Duty Mini Omni Mic features stainless-steel housing, a heavy-duty cable relief and a thick 2.2 mm (0.09 in) cable. DPA’s Heavy Duty microphone is a more robust version of the original lavalier mic that it’s based on.

This microphone can withstand the toughest of conditions, and it’s 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 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 this mic can be modified by selecting the correct grid for the job. Two grids are supplied with each microphone. 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 grids are made of anodized stainless steel. They can be detached from the microphone and wiped clean.
