The DPA 4671 Heavy Duty Omnidirectional Lavalier Microphone (with Loud SPL & Presence Boost) is similar to the CORE 4660 Miniature Omnidirectional Microphone, but its sensitivity has been adjusted to accommodate higher sound pressure levels (SPLs) and includes an acoustically created boost in the higher frequencies, ideal for less than favourable placement positions. All packed into a rugged housing for the toughest of conditions.

✔️ Exceptional audio quality

✔️ Uniform, consistent sound between DPA mics

✔️ Extremely rugged and reliable

4671 Miniature Omnidirectional Microphone, Presence Boost

The DPA Microphones 4671 Heavy Duty Miniature Omnidirectional Microphone is a fantastic lavalier mic, which features a presence boost typically of 5dB at 4 to 6kHz. This is critical for a chest-placed microphone because the frequency range of the consonants spoken is dampened in this position, which results in poor intelligibility. The 4671 has a boost that maximises 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.
To enhance headroom, the 4671 capsule includes a 100 Hz acoustical low-cut, benefitting the built-in preamplifier and wireless system. Furthermore, the low-cut filter removes low-frequency rumble, noise and proximity effect.

Because of its special optimisation 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 4671 is available in black.

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 and 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.
