We have a hardware limiter in there, but it never actually worked right, so we didn't bother to tell anyone about it. I think it might come on at some point, probably keeping an already distorting signal from distorting even more. I think I know a way to modify it so that it does work. I figured that out shortly before I left g-wiz, since we were planning a minor hardware upgrade at the time to fix emi problems. (I don't think that upgrade has been implemented, and probably never will.) It's not a real easy mod, so it's probably not worth the trouble. I'll post it on the web site some day for all you echoplex hardware hackers. As far as input sensitivity, there are some resistor value changes that adjust the input and output gains that are worth doing. Definitely an easier mod. Basically reduces the input gain so that it is easier to adjust, and increases the output gain so that you can get signal levels up to +4dbu. Don't remember it off the top of my head, I'll look for it when I get home. kim _______________________________________________________ Kim Flint 408-752-9284 OEM Engineering kflint@chromatic.com Chromatic Research
