4071 Miniature Omnidirectional Microphone, Presence Boost
The 4071 Miniature Omnidirectional Microphone, Presence Boost is a fantastic omnidirectional condenser 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.
