[QUOTE="gckless, post: 8176282, member: 635756"] Thanks man! Yeah the reflections are pretty frustrating, but it's bearable I guess for now since I'm not competing or anything. My immediate reaction was to assume you made up the word comparator. Lol I have no idea what that is. In any event, I don't believe this is normal. However, in the Zed manual it states "Ultra low THD was not our goal but rather an amplifier which sounds the way we want it to." So maybe it could be a nonissue? I just don't know. I have to write an email to Mr. Mantz I think. I did all that scope testing with the speakers disconnected. There's no way my mids could handle what this amp pushes out. The clipping indicator comes on at ~36V. That's less than half of rated power. I have a feeling it's coming on so early because it's seeing the distortion and picking that up as clipping. I do not think this distortion is normal. Have you ever scoped yours? I haven't tried switching the phase. My crossover point is at 63Hz, so output should not be seen at 100Hz. I tested it with the subs completely off as well, and it was still there. I'm sure if I bumped my crossover point up it would help that out, but I like the sound crossed this low. [/QUOTE]
