      Pristine sound and durability


      • Resistant to humidity
      • Double-vent protection system
      • Available in three colors and three sizes
      • Modular adapter system fits most professional wireless systems

      This microphone offers clean and transparent sound quality with lots of headroom. For years, this has been the chosen headset mic for broadcasters as well as theaters on Broadway, as well as in many auditorium and lecture halls. This is due to its pristine sound and durability.

      The headset construction is unique. You can detach the mic boom from the headset mount to switch it to either the left or right side and then reattach it. Humidity, often an issue in theatrical applications, is not a problem. This microphone is constructed with a double-vent protection system and a drop stopper on the microphone boom. Also, the materials inside the mic are water resistant. These design elements make it very difficult for the microphone to fail due to humidity.

      The microphone’s sensitivity is 6 mV/Pa. This matches the level of the human voice to the general input sensitivity of most wireless transmitters. If powered correctly, the microphone will be able to handle very high sound pressure levels up to 144 dB SPL before clipping occurs.

      IP58 certified

      All CORE by DPA technology microphones are IP58 certified. This durability is achieved through a number of defense mechanisms:
      •    Water-repellant nano-coating of the cover and housing
      •    Hermetic sealing of the sensitive amplifier at the core of the mic
      •    Dual gold plating of the diaphragm

      A bit about omnis

      An omnidirectional microphone has sensitivity at all angles – in principle picking up sound equally from all directions. This gives you extremely natural and realistic sound compared to a cardioid mic. Omni mics are often used for picking up ambient sounds, as well as miking a large sound source such as a choir in a recording situation. Unfortunately, due to their pickup pattern, omnis can also produce a lot of feedback in live situations.

      Nonetheless, we recommend that you try a DPA omni first because, when used close to the sound source, the equal frequency response makes these mics a flexible addition in your audio toolbox. It will often give a more natural sound, it can handle extremely high sound pressure levels, it does not suffer from proximity effect and is not as sensitive to wind, pop or handling noise.

      The slim and round capsules have the same specs. But choose CORE by DPA and you increase the dynamic range from 97 dB to 111 dB.

      In operation, both the omni and directional headsets sound natural even before any equalization, and deliver impressive level without feedback, even when the user is positioned relatively close to a loudspeaker cluster.
