DPA Microphones 4066-OC-A-F34-LH d:fine™ CORE
4066 Omnidirectional Headset Microphone, Beige, with Mini-Jack Adapter

OUR PART #  4066-OC-A-F34-LH


The DPA Microphones 4066-OC-A-F34-LH, a member of the DPA d:fine 4066 Series, is equipped with DPA's proprietary CORE technology, and features an omnidirectional polar pickup pattern. This particular model includes a Mini-Jack adapter for use with Sennheiser Evolution, G2, X2 Digital Wireless transmitters, although, like all d:fine mics, it features a MicroDot connector allowing further expansion/versatility with other 3rd-party systems on the market with DPA's flexible adapter system (additional adapters sold separately – refer to the "ACCESSORIES" tab above, or contact your Sales Pro for more information).

With pristine sound quality plus durability, the d:fine™ 4066 Omnidirectional Headset Microphone headset mic has been the choice for broadcasters as well as theaters on Broadway and London's West End. It features unique construction, allowing you to detach the mic boom from the headset mount then reattach it to either the left or right side. And though it's often an issue in theatrical use, humidity is no problem here; it's made with a double-vent protection system and a drop stopper on the mic boom. Plus, the mic's interior materials are also water resistant. The result is a design that makes it very difficult for the microphone to fail due to humidity. In addition, its surface is matte-gold plated and the ear hooks are covered with a silicone hose.

Mic sensitivity is 6 mV/Pa, matching the level of the human voice to the general input sensitivity of most wireless transmitters. If properly powered, this mic will be able to withstand sound pressure levels up to 144 dB SPL before clipping occurs.

DPA CORE Technology vs Legacy
One of the most clear, consistent, and potent miniature microphones available, the legacy d:fine 4066 is known for working across a wide dynamic range as well as exhibiting low distortion across all SPLs. And now, CORE technology enables you to squeeze a little more performance out of your mics with a 14 dB increase in both THD and Dynamic range:

  • Total harmonic distortion: < 1% THD up to 137 dB SPL peak
  • Dynamic range, typical: 111 dB
  • Increased dynamic range = Increased workable range
  • Increased dynamic range = Less vulnerable to overload

It's a powerful technology at the heart of DPA's CORE miniature microphones. Distortion is minimized, so from a whisper to a scream, you'll experience more clarity and openness.
