The DPA Microphones 4071 Miniature Omnidirectional Microphone, Presence Boost is a lavalier mic that features a presence boost of typically 5 dB at 4 to 6 kHz. This is critical for a chest-placed microphone because the frequency range of the consonants spoken is damped in this position, which results in poor intelligibility. The 4071 has a boost that maximizes speech intelligibility. This microphone will be able to handle sound pressure levels of up to 144 dB before clipping occurs.

When recording voices from mic placement on a performer's body, no frequency below 100 Hz is attractive. For this reason, an acoustical low-cut at 100 Hz has been incorporated in the 4071’s capsule, so the built-in preamplifier (and the wireless system) will have a much larger headroom. Furthermore, the low-cut filter removes low-frequency rumble, noise and proximity effect.

Because of its special optimization for speech, this mic is especially appropriate for ENG news crews since very few ENG mixers can make this type of compensation. It’s also a solid choice for in-studio reporters or even hidden under clothing for film production use.

The 4071 Omnidirectional Condenser Lavalier Mic is based on the original 4060—the very first miniature microphone developed by DPA from the best technology previously only used in hearing aids and measurement microphones.

The 4071 was developed to withstand the toughest of conditions. It contains a 5.4 mm diameter pre-polarized condenser element with a vertical diaphragm. This unique, Double Vent Protection System makes the mic greatly resistant to humidity and sweat. This mic is also designed with a Kevlar-reinforced cable relief, which is built to withstand the constant twists, bends and pulls that are part of the everyday use in harsh environments.

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.

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 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.
