What does the term 'gain' refer to in sound control?

The term 'gain' in sound control specifically refers to the adjustment of the strength or amplitude of an audio signal. It is crucial in managing how much of the audio signal is sent to the mixing console or processing equipment before it is further manipulated or amplified. By adjusting the gain, which can also be called trim or pre-amp in different contexts, sound engineers can ensure that the signal is strong enough to be processed effectively without introducing noise or distortion, but not so strong that it results in clipping or loss of quality. In practical scenarios, setting the gain correctly is fundamental to achieving a clear and balanced sound during performances or recordings.
