I was confused with the speaker ohm switch. I read the manual as 4 ohm and under then use the less than 4 ohm position. I should have used the greater than 4 position. So i was trying to set gains on 4 ohm speakers but the amp thought they were 2ohm. I was clipping at 16v. Brad informed me of the error and put it through it's paces. Thd, sn ratio, etc. The amp is fine. I'm able to push 24v until i see too much noise on the scope. It's taking in a clean 4v signal but arc says it only takes 2.6ish volts. If i keep the input down to 2.6v then i have to turn the amp gains up. With 4v, the gains are all the way down. I like that better. Whether or not that's a good thing, we'll see.
