CHANGING IMPEDANCE
Your microphone is preset to 600 ohms impedance. You can change
its impedance from 600 ohms to 50 k ohms to match your audio equip-
ment’s impedance requirement.
Follow these steps to change impedance.
1. Use a Phillips screwdriver to remove the screw on the lower end
of the microphone. Then using a pair of needle nose pliers, care-
fully pull out the 3-pin connector. Be careful not to break the wires.
2. Carefully pull the low impedance red wire terminal out from pin
number 2 (marked beside the pin on the bottom).
3. Connect the high impedance yellow wire terminal to pin number 2.
4. Matching the terminal base’s plastic tab with the notch on the
microphone bottom, carefully reinsert the wires and terminal base
into the microphone body until the screw hole in the base aligns
with the screw hole in the microphone body. Replace the screw
and tighten it.
USING THE MICROPHONE STAND CLAMP
The supplied microphone stand clamp lets you place your microphone
on a microphone stand (not supplied). Screw the holder onto the top of
a microphone stand. Then slide the microphone into the larger end of
the holder until it is secure.
