Actually, it is not the VHF/UHF ("encoder") mics that are generally
the issue. The real problem is with the HF "desk" mics (MC-55,
MC-60A, MC-80, & MC-85) that use pin 5 to power a preamplifier or
bias the electret capsule. MC-55, 80 and 85 use electret capsules
and require power on "pin 5" or the use of batteries. The MC-60A
is a dynamic mic that will work with the K2/K3 as long as the
preamplifier is bypassed (preamp switch "off"). The MC-90 - a
dynamic desk mic with no preamp - works without modification.
