A signal chain refers to the series of devices and processes that an audio signal passes through from its source to its final output. This can include microphones, mixers, amplifiers, and speakers. Each component in the chain plays a specific role in shaping the sound, ensuring it is captured, processed, and delivered effectively. In a typical signal chain, the journey begins with a microphone that converts sound waves into an electrical signal. This signal then travels through various devices, such as equalizers and effects processors, before reaching the speakers, where it is transformed back into sound for the audience to hear.
