How do I adjust the gain on my microphone?
Turn the dial on your microphone clockwise to increase the gain. Most USB microphones have control knobs right on them, so adjusting the gain takes no time at all. Locate the dial, which will likely be marked gain and have a small, white stripe on it. Raise the gain to increase the volume.
How do you adjust a preamp impedance?
For optimal results, the load impedance should be at least five times higher than the output impedance. So if the microphone has an output impedance of 200 ohms, the preamp should have an input impedance of at least 1.000 ohms.
