Here are some interesting videos related to PA and sound reinforcement systems. Wikipedia defines that a public address system (PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. The term, sound reinforcement system generally means a PA system specifically for live music or performance. A sound reinforcement system for a rock concert or other large event in a stadium may be very complex.

Mixing Live vs Audiophile Home Hi-Fi vs Dinner
https://www.youtube.com/watch?v=Lnh9eo—4o
The video “Mixing Food and Audio” presents an analogy between sound and cooking, demonstrating how the mixing of food and audio can be similar. The creator uses kitchen ingredients to represent musical instruments, blending different sounds to create a complete rhythm section. The video also explains the process of mixing music with bass and guitar to get a stereo mix and how in a live mix, things can be readjusted easily, but when producing a final recording, the mix can not be altered in the same ways. The speaker suggests that it would be better to send different instruments separately to the listener rather than mixed together, creating a more realistic and immersive experience.
