DPA 4071-OC-C-B00 Core Presence Boost, Loud SPL Omnidirectional Lavalier Microphone, Black, MicroDot

The 4071 Miniature Omnidirectional Microphone, Presence Boost is a fantastic lavalier mic, which 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 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 have the ability to make this type of compensation. It is also a fantastic choice for in-studio reporters or even hidden under clothing for film production use.

The 4071 is available in three colors: black, beige and white. An even more robust, heavy-duty version is also available.
