What is the Gain of Microphone & Ways to adjust it

You can modify the volume of the signal conveyed to your computer by adjusting the microphone’s gain level, a capability found in microphones. This can help ensure the sound quality is constant and undistorted throughout the entire recording. It might also help you avoid distortion when recording or streaming, which is an advantage.

Gaining on a microphone is one of its most important components, but it is also misunderstood. Before a signal is fed into a mixer or amplifier, this step raises or lowers the signal’s volume to prepare it for processing. Either to ensure that the signal is powerful enough to be heard correctly or to prevent it from being overly loud and clipping, this can be done to ensure that the signal is strong enough.

What exactly is a gain on the microphone, how does it function, and what is the proper way to use it? All of these questions and more will be answered in this article!

What is microphone gain, and what does it do?

The amount of amplification applied to a microphone signal can be referred to as the microphone’s gain. The sound volume picked up by the microphone can be adjusted using this.

The gain of the microphone can be changed to alter the level of the sound being picked up by the microphone. Additionally, it can amplify or attenuate the strength of particular frequencies contained within the signal.

Microphone gain is one of the most crucial factors when recording audio. Adjusting the level of the sound being caught can be done with its help to get the exact tonality and volume that one desires.

To ensure that the audio captured is neither too loud nor too quiet, it is essential to check that the gain setting on the microphone is accurate. If the microphone gain is adjusted too high, it can result in distortion and noise. If turned down too far, the recorded sound will be very soft and difficult to pick up.

What is Volume?

The dB output of a sound system is referred to as the volume, which is also sometimes referred to as “amplitude.” Simply put, it refers to the volume of the music being played through your speakers.

The volume measures how loud a signal is once it has been processed and has exited a sound system. In its most basic form, loudness refers to our perception of how loud something is. The audible level of the source that is being sent out of your speakers is what is referred to as the volume of a signal in the area of mixing.

Are you playing your bass or guitar through an amplifier? The volume knob on the amplifier controls the output level of your amplifier’s speaker or speakers. The same principle applies to the volume knob in your vehicle’s audio system.

The most important thing to consider is that adjusting the volume does not affect the tone of the sound produced by the speaker. The volume control on your system merely adjusts the overall loudness or amplitude of the sound.

How to Set the Gain of a Mic?

As was just pointed out, the gain control is the very first element that affects the unprocessed signal coming from the microphone; as a result, it is typically situated at the very top of a mixer board. The objective is to adjust the gain level to be high enough to bring the input signal up to a normal level but not so high that clipping and distortion occur.

The Pre-Fader Listen (PFL) button may be found on most mixers, a fortunate inclusion. Through the use of the LEDs located on the mixer board, it is possible to view the strength of the signal. You want to maintain the signal at a level that is just slightly lower than the one at which the peaks begin to enter the red zone. Once established, leave it.

Gain controls the amount of distortion produced by a guitar amp; therefore, the level of distortion you wish to achieve is a matter of personal preference. Many novices tend to set the gain way too high (typically to 10) because they believe doing so will create an incredible new sound.

That is not the case. Everyone has already experimented with the same thing and eventually discovered that they can achieve a far more pleasing sound by turning the gain down a few notches.

Step 1: Changing the gain setting on an internal preamp (In A Mixer, Etc.)

Step 2: Activate the source of the sound.

Step 3: Put the PFL button on the mic channel into the on position.

Adjust the gain until the meter indicates a healthy level, which is indicated by significant movement on the bars but does not go into the red.

How to adjust a computer’s microphone input level?

Whether you’re using a computer or another device to record audio, changing the microphone’s input level is essential if you want the highest sound quality. The amount of signal transmitted from the microphone to the recording device can be adjusted using the gain knob. If it is turned up too high, distortion will occur; if it is brought down too low, a weak recording will result.

Finding the optimal input level may require trial and error, but the effort is well worth it if you want your recordings to sound their best. The following are some suggestions that can help you get started:

Determine first the highest possible input level for the device you’re using. You may either find this information in the handbook that comes with the gadget or conduct a search for it on the internet.

The following step is, to begin with, the microphone gain turned down, then gradually turn it up until you start to perceive distortion in the recording. Move back a little from that point to locate the optimal position.

If you are working with a computer that runs Windows, there is a helpful application that you can use called the Level Meter that will assist you in determining the appropriate input level. It is a small application that may be found in the system tray of your computer and appears as follows:

The five bars on the Level Meter each represent a different input level at the moment. It is optimal for the green bar to be as close to the top as it can get without entering the red zone, which denotes distortion. If it isn’t, you can change the microphone input level to make it so.

Once you have determined the appropriate input level, it is recommended that you save your settings so that it will be simple to reproduce them later. You may accomplish this on Windows by clicking the small arrow next to the Level Meter and then picking the “Create Preset” option from the drop-down menu. Please give your preset a name, then click the OK button.

When you want to record some audio on your computer, you must load up your preset, and you’ll be ready to go.

[Bonus Section: Benefits of Adjusting Microphone Gain]

You can change the volume of your voice by adjusting the gain on your microphone, which is a setting on most modern microphones. This can be of great assistance when you are capturing video or audio because it will ensure that your voice is at the appropriate level. This can be quite beneficial.

If the microphone gain is set too low, your voice will not be audible to the listener, and if it is set too high, your voice will be very loud and may sound distorted.

You may make sure that you and the others listening to you are hearing your voice at a tolerable volume by setting the gain on the microphone. This is essential because it will help you avoid having to shout or talk in a soft voice, making it challenging for others to understand what you are saying.


Can Gain Be Considered the Same Thing as Distortion?

The amount of input given to a system, whether an amp, a console, or an interface, is referred to as the system’s gain. When comparing the two, it is essential to distinguish between distortion and compression because distortion is the sound you get from your console, interface, or amp if you push it too far.

What Happens When the Gain Is Too high?

Your audio will reach the point of clipping or distortion if the gain at the input stage is turned up to an excessively high level. This might be good or negative, depending on what you’re trying for. You may want to obtain some distortion with an amplifier, but you may want a clean tone for digital audio. It all depends on what you’re going for.

What Amount Should I Set My Gain At?

To get the most out of your music, it is recommended that you set your gain so that you are right where green meets yellow. This is because most systems correlate the color with the amount of gain, with green being the least gain, yellow being in the middle, and red representing clipping or distortion.


Microphone gain is an essential component of recording that should under no circumstances be neglected. You will be able to make recordings that are pristine and unmistakable if you are familiar with the fundamentals of microphone gain and the correct way to apply it.

Experiment with different settings to find out what works best for your project, but make sure to keep in mind the objective of the recording as a whole the entire time. You will be able to consistently achieve fantastic outcomes with only a little bit of work. Thank you very much for reading!
