Nevaton MC 403

655.00 excl. VAT

Nevaton’s boundary layer microphone is a solid solution for recording acoustic instruments, kick drums, speech, male and female vocals, and for use in post-production and broadcast. Their thin, unobtrusive design makes them ideal for live stage recording, fitting nearly anywhere on a set or in a studio. When mounted on a boundary such as table, floor or wall, Nevaton’s boundary microphones double in sensitivity, while their vibration-proof construction lessens overall interference levels.

Nevaton MC403 – Boundary Layer Microphone 

Acoustic features and construction

The microphone transducer is a pressure sensor with a gold-plated diaphragm, 12 mm in diameter.
It is flat and small. If it is mounted in the surface area of a boundary (plate) like on the floor, on the walls, on the table etc, a number of advantages are gained: The sensitivity of the microphone doubles, the S/N ratio raises and the polar pattern becomes hemispherical.
This method minimizes the interference effects, which usually happen when microphones are placed near reflective surfaces.
The microphone has a vibration proof structure. It provides high output voltage and features a smooth frequency response for all angles. The mic can handle a maximum SPL of 142 dB.

The MC 403 uses transformerless circuitry, balanced output and operates on 9-52V phantom power. It has a ultra-low self-noise of only 6dBA!
A gold-plated XLR-connector is used as an output-connector.

Operational quality

It has non-slip rubber-pads for horizontal positions, and specially threaded holes for mounting it on walls. The microphone is very small and unobtrusive and can be easily hidden on stages or conference tables.
The mic is supplied with an aluminium case.

Like all Nevatone microphones, the MC 403 is entirely handmade and is carefully tested in the acoustic laboratories of the Nevaton homebase in St.Petersburg before it leaves the factory.
