Microphone beyerdynamic professional

The microphone is from the old company beyerdynamic, which has been creating microphones for many years and still creates to this day. In those days, there were no such companies as shure and senhauser, they appeared later. This microphone is universal and works exclusively with phantom power.Model opus 81, condenser type.More exact specifications are attached in the photo. I'll exchange it for something of equal value.
