What is the primary purpose of gain pads on a digital mixer?

Gain pads on a digital mixer are specifically designed to adjust the input gain for audio channels. They act as attenuators that lower the incoming signal to prevent distortion when the audio source is too hot, or too strong. By doing this, gain pads ensure a cleaner and more controlled audio signal, allowing for better mixing and processing of sound. Proper input gain adjustment is crucial for optimizing the signal-to-noise ratio and achieving a balanced mix.

In contrast, while controlling audio output levels is essential in the mixing process, the function of gain pads is linked specifically to the input stage. Similarly, adjusting power supply or setting the recording format does not relate to the operation of gain pads, as these functions are managed through different components of the mixer. Understanding these distinctions highlights the critical role of gain pads in achieving high-quality audio capture and management.
