Excellent microwave background is a radar that are not large diaphragm mics, the diffrence the position of each sound in Stereo, accepts high sound pressure levels due to its low sensitivity but sufficient to music with a good low noise prampli: 8 mv for Easter. Excellent omnidirectional, it does no better with the DPA 4004-and-QTC1 QTC50-QTC40-QTC30 of Earthworks.
Other electrostatic microphones are older design that can still love, even if they are less efficient or more gnralement sometimes moisture sensitive.
But beware of confusions made on the site, all microphones are modern electrostatic membrane technology or traditional nikel mylar dor or alumina with a rear electrode called a back-electret, DPA as earthworks referred to here . The electric field is created by the rear electrode over grazing in an electrostatic charged matriau hot, which is not so commonly known lectret microphones mounted on the t lphones phones that only the membrane is electrostatic, and cre loaded matriau this field. Lgre having to be to keep the bandwidth and the sensitivity and the membrane becomes heavier design s'paissit To create this field electrostatic stable and sustainable, there is a compromise and the High performance is lost, life, sensibilitbande bandwidth. I think this recall is useful for many technological diffrencier choice.
The advantage of back-in electrostatic lectret is amlioration performance against traditional technology electrostatic voltage bias, lack of converter To create the tension of 50 200 V and lack of sensitivity of the cell vis - vis the humidity is an advantage in noise. Having said that the microphone is, like all electrostatic microphones, moisture sensitive because it contains an electronic circuit whose components are moisture sensitive as all that electronic tidit not g nral. More here because the electrostatic micro whatever contains high-ohmic Resistors, capacitors and multilayer Cramique an epoxy printed circuit that acts like a sponge. All my microphones, DPA Earthworks as me and other possible problem of noise when various stocks between 65 and 80% humidity without being Global Warming few degrees atmosphere. This is the price to pay for the quality of the electrostatic in almost everyone but it is a default in the electronic gnral.

OVERALL OPINION

One of the best microphones for multichannel even if it is not a cardioid! But it is also a perfect all-purpose omni prices INTERESTED.
