How to Hook Up a Microphone to an Amp


Connecting an microphone to a guitar amplifier is not ideal for a live sound setup, but it can suffice. Audio engineers usually hook up microphones to PA speakers to suit the frequency range of the mics better. You can hook your mic up to an amplifier by using an XLR to 1/4-inch converter cable. These cables can be purchased at many musical instrument stores. The setup process should only take a few minutes to complete.

Things You'll Need

  • Female XLR to 1/4-inch audio cable
  • Insert the female XLR cable end into the male XLR input of the microphone. You will hear a "snap" when the cable has locked into position.

  • Insert the 1/4-inch cable end into the "Audio Input" jack of the amplifier.

  • Plug the amplifier into an electrical outlet and turn on the device. Turn up the "Master Volume" knob on the amplifier.

  • Talk into the microphone and listen for audio coming through the amplifier. Continue talking through microphone as you look for the "Low", "MID," and "High" knobs on the amplifier. These knobs control the equalization of the amplifier's sound and cover the low, mid and high frequencies of the audio signal.

  • Adjust the equalization knobs as you continue talking through microphone. Continue experimenting with the knob positions until you are satisfied with the audio quality.
