I rather think a low impedence mike is generally preferred. Note the pinout
information on P. 13 of the manual where a low impedence mike (approx. 600
ohms) is indicated. However, the K3 can be used with either high or low
impedence microphones, and that is dealt with via a menu setting. See P. 20
of the owners manual, left column, last paragraph.
