Have you noticed the impedance matching of the microphone?

Author:admin   AddTime:2021-07-29

Impedance matching: When using a microphone, the output impedance of the microphone and the input impedance of the amplifier are the same as the best match. If the mismatch ratio is above 3:1, the transmission effect will be affected. For example, when a 50Ω microphone is connected to an amplifier with an input impedance of 150Ω, although the output can increase by nearly 7Db, the high and low frequencies will suffer significant loss.
