DPA 4071 CORE Omni Lavalier Microphone, Presence Boost

Product overview

The DPA 4071 CORE is an omnidirectional miniature lavalier microphone with a presence boost of typically 5 dB at 4 to 6 kHz, optimised for chest placement and maximum speech intelligibility.

On the chest, the frequency range of spoken consonants is damped; the 4071's presence boost brings it back and maximises speech intelligibility. Because no frequency below 100 Hz is attractive when recording voices from a microphone on a performer's body, an acoustical low-cut at 100 Hz is built into the capsule, so the built-in preamplifier and the wireless system have a much larger headroom; the low-cut also removes low-frequency rumble, noise and proximity effect. The 4071 handles sound pressure levels up to 144 dB before clipping.

Like all 4060 Series microphones it comes with CORE by DPA, a powerful technology at the heart of DPA miniature microphones that minimises distortion across the entire dynamic range, increasing audio clarity and openness. The 4071 CORE is offered with the MicroDot connector, in black, beige or white; adapters screw onto the MicroDot connector gently yet firmly until they click.

A 5.4 mm pre-polarised condenser element with a vertical diaphragm, the Double Vent Protection System against humidity and sweat, and an aramid-reinforced cable relief built to withstand constant twists, bends and pulls make the microphone extremely rugged and reliable in the toughest conditions.

DPA 4071 CORE: frequently asked questions

What does the presence boost do?

The 4071 has a presence boost of typically 5 dB at 4 to 6 kHz. On the chest the consonants of speech are damped, and the boost brings them back for maximum speech intelligibility.

Why does the 4071 have a low-cut at 100 Hz?

No frequency below 100 Hz is attractive when recording voices from a microphone on the body. The acoustical low-cut in the capsule gives the preamplifier and the wireless system a much larger headroom and removes low-frequency rumble, noise and proximity effect.

Which connectors are available?

The 4071 CORE is supplied with the MicroDot connector. The DPA modular adapter system fits most professional wireless systems, and a DPA XLR adapter gives P48 phantom-powered wired use.

How should the microphone be cleaned?

The cable and the protection grid are the parts to clean, using demineralised water. After exposure to sweat, rinse the microphone in demineralised water and let it dry out; drying it between exposures to humidity also extends its lifetime. Remove tape, glue or make-up from the cable after use with organic oil or lukewarm demineralised water.

Where can I buy the DPA 4071 CORE in India?

The DPA 4071 CORE is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: ENG: chest-placed news microphone

ENG news crews miking reporters and interviewees.

Connections

Setup

1. Clip the microphone on the chest.
2. Connect it to the transmitter through the matching DPA adapter.
3. Record: the presence boost keeps speech intelligible.

Tip: The 4071 is especially appropriate for ENG news crews, with its special optimisation for speech.

Workflow 2: In-studio reporters

Broadcast studios miking presenters and reporters.

Connections

Setup

1. Place the microphone on the chest.
2. Connect it through a DPA XLR adapter or a wireless transmitter.
3. Set the gain; the 4071 handles up to 144 dB before clipping.

Tip: The typical 5 dB presence boost at 4 to 6 kHz restores the consonants that are damped on the chest.

Workflow 3: Film: hidden under clothing

Production sound teams concealing microphones on actors.

Connections

Setup

1. Choose black, beige or white to suit the costume.
2. Hide the microphone under clothing on the chest.
3. Connect to the transmitter and check speech intelligibility.

Tip: The 4071 is a fantastic choice hidden under clothing for film production.

Workflow 4: More headroom on wireless systems

Sound teams running body-worn microphones on wireless.

Connections

Setup

1. Fit the microphone on the body.
2. Connect it to the transmitter through the matching DPA adapter.
3. Set the gain with the extra headroom in mind.

Tip: The acoustical low-cut at 100 Hz gives the built-in preamplifier and the wireless system a much larger headroom.

Workflow 5: Wired use with phantom power

Studios, conferences and installations using wired microphone inputs.

Connections

Setup

1. Connect the MicroDot connector to the DAD6001-BC XLR adapter, screwing it on gently yet firmly until it clicks.
2. Switch on P48 phantom power at the input.
3. Run the cable; up to 300 m is possible with the XLR adapter.

Tip: The microphone also works from 12 V.

Workflow 6: Speech without rumble

Recordists capturing body-worn speech in busy surroundings.

Connections

Setup

1. Place the microphone on the chest.
2. Connect it to the recorder or transmitter.
3. Record: the low-cut keeps rumble out of the speech.

Tip: The low-cut filter removes low-frequency rumble, noise and proximity effect.
