High impedance can load low impedance. Just the voltage will be on the low side, requiring lots of microphone gain. Many Shure microphones are switchable dual low and high impedance. High impedance is probably greater than 50,000 ohms. There are transformers to match 500 ohms microphones to high impedance. 73, Jerry, K0CQ -- Entire content copyright Dr. Gerald N. Johnson.
