The M81’s flat frequency response and exceptional midrange clarity make it a go to for brass, toms, and guitar amps on the stage and in the studio.



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.

The M81 is available in a variety of colors and finishes through our Custom Shop, and in Low-Profile (M81-SH) and Wireless (M81-WH) packages.

Frequency Response

“It can be very difficult to obtain the kind of clarity and placement on backing vocals that is required while mixing precision-based material, particularly when the mics are used in conjunction with traditional wedge monitors. The TELEFUNKEN M81 vocal mics produce such a smooth quality vocal range while maintaining an isolated, somewhat remote characteristic to the backing vocals that I was able to place them in the mix with pinpoint accuracy. I believe this was due to the inherent rejection of ambient interference of the stage across the board.”
