The Beyer M160 is a double ribbon hypercardioid microphone which in addition to its smooth ribbon colour stays pleasant off axis. As with all these microphones , the output level is pretty low, and they need a good preamp. The one you can see on the right has been modified by Jean Marie Mallet andincorporates a preamp which gives it the output level of a static. It also has an amortization helicoidal chamber at the back of the capsule. Those marvels give their best when recording a flute, a guitar a violin or as ambient microphones.
