The 4660-OL-H-F00 is part of DPA Microphones' d:screet™ Heavy Duty Mic Series which is made for situations where you require maximum security and where the visual size of the mic is less important. It features a stainless steel housing, a heavy-duty cable relief and a thick 2.2mm (0.09") cable. The d:screet Heavy Duty microphones are a more robust version of the original mic series they are based upon.

DPA's Flexible Adapter System

The available adapters for wireless systems provide you with lots of flexible, simple, and affordable possibilities. No longer are you bound to a single wireless system. As your circumstances change, you can just swap your adapter, rather than incur the cost of a completely new microphone (adapters sold separately). When you make the switch, you won't hear any loss or change in sound quality.

With this system, DPA's miniature microphones will work with all leading wireless mic solutions such as Lectrosonics, Sennheiser, Shure, Sony, Wisycom, Zaxcom and many more (transmitters sold separately) via DPA Microphones' ingenious adapter system, a one of a kind in the industry. It protects your investment in fantastic sound for years to come.

Note: to complete this microphone setup, you'll need to add a MicroDot-compatible adapter (sold separately). Please refer to items located under the "Accessories" tab above, or if necessary, contact your Sales Pro for more information.
