The M81 is a proven choice for countless sound sources both in the studio and on the stage. It possesses the same condenser-like response, minimal proximity effect, and superior feedback rejection one expects from a TELEFUNKEN Dynamic Series microphone. A smooth frequency response, clarity, and wealth of body make the M81 an ideal tool for taming brighter vocals, guitar tones, and fattening up toms, horns, or other thinner sounding sources. Built around a low-mass diaphragm designed to reduce proximity effect, and a custom-wound impedance matching transformer, the M81 features intelligent design and American-assembled construction, making it is an excellent first choice dynamic for most situations.
