- UM : EA
Made for situations where you require maximum security and where the visual size of the mic is less important. The Heavy Duty 4661 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 mics they are based upon.
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
