Allow me to help you understand what Signal Flow is. Also this is an excerpt from my book Essential sound principles.
Signal flow is one of the most crucial concepts to grasp when working with live sound. The course of an audio signal from its source, to its output, is known as signal flow. It’s how sound travels from an instrument, or input, into the audio console. It’s also about what path the signal takes through the console, before finally going out of the speakers, which is what sound mixing is all about.
Loudspeakers, crossovers, amplifiers, signal processors, audio consoles, microphones, DI boxes, sub snakes, splitters, and other pieces of equipment are all part of a sound system19. For this equipment to perform effectively, the audio signal must follow a precise path through it. You can correctly wire all of these components together if you understand the signal flow.
The stage’s inputs must be routed to the snake, which must then be routed to the consoles, which must then be routed to the system EQ and processors, which must then be routed to the amplifiers, and ultimately the amplifiers to the speakers.
