Description

With its elegant look and performance, the 4060 Omni Boundary Layer Microphone is the perfect microphone for use in boardrooms, conference facilities, courtrooms, teleconferencing rooms and other places for audio reinforcement or recording. This product is designed to work optimally when placed on a tabletop, but it also performs well on any other hard, flat surface. This microphone combines ease of use and placement with high sensitivity and a wide dynamic range.

Features

  • Ideal for use in boardrooms and conference facilities

  • Sleek low profile Scandinavian Design

  • Optimized to boost speech intelligibility

  • Modular adapter system fits most professional wireless systems

 

CORE by DPA

The 4060 Omni Boundary Layer Microphone uses CORE by DPA, a powerful technology at the heart of our miniature microphones. CORE minimizes distortion across the entire dynamic range, increasing audio clarity and openness.

Application guide

Placement guide

The 4060 Omni Boundary Layer Microphone is a transducer that should always be placed on a surface that reflects sound. By doing this, you will benefit from the special characteristics of the sound field found here: a 6 dB gain of direct sound and only 3 dB gain of diffuse sound. Hence, the sound captured has both a greater clarity and intelligibility compared to sound captured above the surface.

The microphone can be placed on any surface that reflects sound, like tables, speaker podiums, etc. Even if a table is covered with cloth, the product will work due to the shape and size of the disc. The microphone has been designed to ensure high-frequency clarity and speech intelligibility under most conditions. The low-frequency response is, to some extent, dependent on the area of the boundary. However, for speech pick up, even small areas like podiums are adequate. The microphone can be placed in essentially any position on the surface, even close to the edge. However, try to avoid placement that may receive reflections from vertical faces as this may cause coloration of the sound (comb-filtering). For tables longer than 6 m (20 ft), it is recommended to use more than one unit.

Cleaning guide

A dry cloth can be used to clean the surface of the microphone. Do not use any cleaning agents to clean the unit as fluids can damage the microphone.
 

Cleaning the microphone cable

Residue from tape, glue or makeup on the cable must be removed after use. Leaving these substances on the cable over longer periods of time may etch into the cable jacket and will make the cable more susceptible to breaks. The cable can easily be cleaned using organic oil (e.g. olive oil) or lukewarm, demineralized water. Do not bend the cable or rub it harshly since this may stress the inner cores of the cable and cause them to break over time.
