Getting loud "pops" when turning on your system?
Posted by Rick Shao on 13 November 2015 05:51 AM

Voltage and signal transients (peaks) are sent through any circuit when equipment is powered on or off. These signal surges can be potentially damaging in the long run to components like power amps and especially speakers. An effective prevention is to think of the flow of sound material or program from its source to its destination. Always turn the components on in the direction from source through destination (i.e., first plug in mic, then turn on mixer, signal processor, and, finally, the power amp/speakers). Conversely, turn them off in the opposite direction - from destination backwards toward the source. This way, the feeder transients from the mixer and signal processor will never be amplified by the power amp and broadcast at high volume through your speakers.
