The U 87 is probably the best known and most widely used Neumann studio microphone.
The U 87 is equipped with a large dual-diaphragm capsule with three directional patterns: omnidirectional, cardioid and figure-8. These are selectable with a switch below the headgrille. A 10 dB attenuation switch is located on the rear. It enables the microphone to handle sound pressure levels up to 127 dB without distortion. Furthermore, the low frequency response can be reduced to compensate for proximity effect.
Industry-standard mike with excellent sound and reliability
This is a famous model of condenser microphone which has been in production for many years. I own a number of reasonable quality large-diaphragm microphones and, of these, this is the one which I use most often in my project studio. My main uses are for male vocals and acoustic guitar, and for these applications it performs very well. The sound is clear with, to my ears, no obvious loudness or quietness in any frequency range. I have also used this to record electric guitar amplifier (I'm always a little nervous about this as the U87 is rather expensive so I tend not to subject it to too loud a signal close up). This has worked ok although for this use I would often prefer a dynamic microphone, or perhaps a combination of each type. In summary this is a classic high-quality all-rounder. If I had to pick just one mike from my collection to use on everything this would be it.
I'm not so technical and don't no every detail. But this microphone sounds perfect. I think that I will never buy another one. I'm completely satisfied how it sounds. It doesn't cut the bass on the vocals, like some of the cheaper ones have done, that I have bought.
