What is signal amplification in AV systems?

Signal amplification in AV systems refers to the process of increasing the power of a signal to produce a clearer and more robust output. This amplification is essential in various AV applications, as it helps to ensure that audio and video signals maintain their integrity and are delivered effectively to speakers, screens, or other output devices. By enhancing the signal's strength, amplification mitigates the effects of distance and interference that could degrade the quality of the audio or visual experience. Proper signal amplification is crucial in achieving optimal performance, especially in larger venues where signals may need to travel longer distances.

Other aspects of AV systems, such as adjusting audio and video sources or mixing multiple signals, do play critical roles in the overall sound and image quality but do not specifically relate to the process of amplification. Altering sound frequencies may involve equalization processes that shape the tonal quality of the signal rather than increasing its power, which further distinguishes these functions from the concept of signal amplification.
