Hello Friends! I had a question regarding setting up amplifiers. I have always had powered mixers or speakers so I have never really dealt with amps. I am totally lost on where to set the input 1 and input 2 levels on the amp. The amp is a powerful amp. Somebody told me start from 0 and then turn the amp knobs until levels come to your liking. However, somebody told me this is dangerous way. I ask humbly if somebody could please help. Thank you all so much for your time.
