greetings, i need help, i would like to know if it is normal that my amp even when it has all volume nods off makes a sound like huuuummmmmmmm, i have a rg200g3.
Yep - Ive got the same amp and the same nasty hum.
Its getting into the power amp stage from the AC supply - and is just really sloppy design. (Ive been an audio designer for 35 years).
Im trying to record with it and its hopeless.
Also - do you find it really really "boomy" at the bottom end?
I have to cut the bass loads, which is just a waste of power.
