In addition, in the home theater speaker system, attention should be paid to the order of power on and power off. When starting up, turn on the front-end equipment such as sound source first, and then turn on the power amplifier; When shutting down, first turn off the power amplifier, and then turn off the front-end equipment such as the sound source. If the audio equipment has a volume knob, turn the volume knob down before starting and shutting down. The purpose of this is to reduce the impact on the speakers when they are turned on or off.
