Reviews around ac noise (1.00 of 5)
EMB Pro 700-watt Digital Karaoke Mixer Stereo Amplifier EBK37

AC noise is my another concern for some low end amplifier from my past experience of building audio amplifier myself

This design has no problem but a risk of ground loop can be built up when you construct your audio system which will introduce significant AC noise

In my case, my desktop with 3 prong power was built into my audio system thus formed ground loop with this new amplifier and introduced big AC noise in the beginning
