Gain controllers, also known as gain adjusters, are devices used to regulate the output of a signal. They are commonly used to change the output levels of audio signals, but they can also be used to adjust the level of video signals.

Gain controllers work by increasing or decreasing the gain of a signal. This is done by adjusting the amount of amplification that is applied to the signal. When the gain is set too high, the signal will become distorted, while when the gain is set too low, the signal will not be able to reach the intended destination. Some gain controllers also have the ability to adjust the frequency response of a signal.

In an audio system, gain controllers are typically used to adjust the volume of the system. It can be used to compensate for differences in acoustic properties or to balance out any other acoustic differences. In a video system, gain controllers are used to adjust the brightness and contrast of the video. They can be used to adjust the picture quality and make the image look sharper and clearer.

Gain controllers can also be used to match the levels of different components in a system. This is especially useful when making connections between components with different output levels. By adjusting the gain of the components, the output levels can be matched to ensure all components in the system are at the same level.

Gain controllers are a key component in many audio and video systems. They allow users to customize their system and ensure the audio or video signals are being sent properly.
