Introduction
 
The mains hum is generated by alternating current and contains multiple harmonics of its fundamental, which typically is either 50 or 60 Hz.

I&amp;#39;m usually trying to get rid of a seemingly much softer hum in speakers and audio players.

My mains hum sounds different : ) Maybe inductive or capacitive pick-up. One option could be a transformer. I wonder if an audio transformer could be used, but with a string of resistors on both Live and Neutral on the primary side.&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=8693&amp;AppID=251&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
