Why does my speaker pop when I power my audio source on and off?
When powering your audio source (Mixer/Interface) on and off, It is standard behaviour for the connected speakers to emit a 'pop' noise.
It is safe practice and industry protocol to ensure that your speakers or power amp (for Passive Speakers) are the last device that you switch on, and are the first thing that you switch off. By following this you will stop any pop noises when powering your mixer on and off.
