Dear Mr. M5, This tool measures DISTORTION. Yes it takes a lot of power to build a real time analyzer to measure distortion. That is what it does, that is why it works. On top of that I did it in 100% analog. This is not a toy, don't kid yourself or lead other people to think it is especially when you didn't know. Tony D'Amore D'Amore Engineering Great step. Obviously my next question is what are you using to calculate distortion (ie which harmonics etc) and at what level you consider it clipping. Glad you took the time to come here, thanks. I apologize for sounding like I inferred it was a clipping indicator. Of course even if it works I still don't see the value in knowing you are clipping for those that aren't chasing tenths on a meter. without being confrontational or anything, can i ask you this.......do you think its good advice for someone to just turn the gain knob up and hope for the best? I actually think your last statement is ass-backwards because if i was chasing numbers, i wouldnt care about distortion and a little clipping would get you more power. Dirty power that your system can handle for a burp, but still more power. For a regular system, to set your gains properly you should use an O scope. This product is designed to replace the O scope (for gain setting purposes). How about I make this simple with a question, can you hear the difference between 900w and 1000w? you are incredible.... if anyone wants any REAL info, i will have more as the product continues to improve, before we even release it. i will also, like i said, send a few out to some REAL installers, even REAL backyard installers who like to do things right.... for beta testing. Of course there is always info on my site. I would be glad to keep SSA posted but it seems like this place is hostile lately. If you guys want, i can though. All questions, even with doubts, can be answered as long as your not a dickface about it. Is that such a hard thing to do? At least at this site, you can state your own opinion and disagree with somebody without getting banned, like over on your site... And over here you don't have 10 people trying to PM you pricing on a certain product every time its mentioned in a thread. As I'm not saying anything bad about your forum, just a few people there, and your admin. Who got pissed because I said the letters DAT, without saying ONE thing ever bad about them.
