Description
The DPA Microphones 4066 CORE Omni Headset Mic offers clean and transparent sound quality with lots of headroom. Due to its pristine sound and durability, for years the 4066 headset mic has been the chosen solution for broadcasters, shows on Broadway, and many events taking place in auditoriums and lecture halls.
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 several 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
About Omnidirection Microphones
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.
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 and can handle extremely high sound pressure levels. DP omni mics do not suffer from proximity effect and are not as sensitive to wind, pop or handling noise.
