How Do You Use a Microphone Jack as a Line?

Published in Audio Engineering 2 mins read

You can use a microphone jack as a line input by using a microphone-to-line adapter. This adapter converts the low-level signal from a microphone to a higher-level signal compatible with line-level inputs.

Here's how it works:

  • Microphone jacks are designed for low-level signals, typically used for microphones.
  • Line inputs are designed for higher-level signals, typically used for instruments, audio interfaces, and other devices.
  • Microphone-to-line adapters have a built-in preamplifier that boosts the signal from the microphone to a line level.

Here are some practical examples:

  • You can use a microphone-to-line adapter to connect a dynamic microphone to a mixer or audio interface with only line inputs.
  • You can use an adapter to connect a microphone to a guitar amplifier with a line input.
  • You can use an adapter to connect a microphone to a computer's microphone jack, which is often a line-level input.

Remember:

  • Not all microphone jacks are the same. Some may have a different impedance or voltage requirement, so it's important to choose the right adapter for your specific microphone and device.
  • Using a microphone-to-line adapter can sometimes introduce unwanted noise or distortion. It's important to use a high-quality adapter and to adjust the input gain on your device accordingly.
