All user reviews of 2/5 for the Audio-Technica AT822

Audiotechnik AT 822 Stereo electret. I even think it is a back electret.
Micro-making and the instruments or small groups

Two cardioid capsules XY, said phase coincidence.

OVERALL OPINION

I use the microphone for several years for the realization of my trio recording live or in rehearsal but also in the creation of models of presentation of the group (Keith style jazz). In these cases I use it as head over to my piano and drums and bass live against.

I also tried to use it for the sound of soundscapes.

For the same applications I used among other electrostatic microphones AKG, among others, the C1000, but who do very well outdoors, home of DO21B Lem connected SSM2017 PA, preamp economical, easy to perform and efficient.

Some qualities but major defects.

For the overall catches of the trio, he is doing well. The sound is OK if well placed and if the acoustics of the place is suitable.

In over head, it is very acceptable. I usually reinforced by a bass drum mic. Good reproduction of the stereo. Good return of cymbals and respect for stamps.

The problems start outside and to the point. First, real lack of sensitivity to power a small DAT or MD. Soon we are confronted with the problem of breath very quickly becomes prohibitive.

Another problem is its extreme sensitivity to wind noise, which requires a high performance full windshield. However, I found a very effective and very inexpensive. Just wrap your microphone of the covers made in synthetic fur. To do this, you get an old jacket sleeve synthetic fur, close to the end and remove the lining inside. I guarantee the result to be tested by strong winds. It has the efficiency of a real dog but for 5 or 10 € to emahus instead of 150 or 200 € in Rykote.
Another proposal of the same kind of Tono Bruno that seems good: http://bga.cga.free.fr/Numerique/Micro/index.htm
Proposal that I found just now.

In all cases, control is imperative that the device does not degrade as an acceptable response in the treble.

Finally, very high sensitivity to noise of contacts. In the studio it does not pose a problem mas outdoor micro point!

In no tell me it is enough to Inrush the low-cut filter, to which I retorted "that is and what is so then the fidelity of the microphone."

Value for money pretty average. As a small micro ECM SM907 Sony is doing better at this level, even if overall it is less efficient but two times cheaper. Some of my students are surprising results with it.

If it again? Probably not. Little choice in this range of microphone and price, but it is ...
