TonyD'Amore Posted June 16, 2011 Report Share Posted June 16, 2011 That signal is not clipped. The spike looks to be from having a crossover on or something like that. ...did you read? At all? That was the entire point of the post. Dirty signal doesn't necessarily have to be clipping. Distortion lives in other ways. I read fine but you missed my point. The spike on the sine wave is not distortion imo but from something else like noise. I have seen this before. That distortion in the waveform is caused by a Class A/B amplifier with the output device bias adjustment (internal) set too low. This is called "Crossover Distortion". NO not Crossover as in Low Pass ect! Crossover as in where the waveform crosses the 0V point and goes from positive voltage to negative voltage. The DD-1 looks for harmonic distortion, that is anything that is a harmonic of the fundamental. What that means is if you are playing 40Hz (the fundamental), the tool looks for things that are not 40Hz, which any noise, "spikes" whatever are not going to be 40Hz because if they were they would be the same as the fundamental and you wouldn't see them at all. Harmonic Distortions of 40Hz would be 80Hz, 120Hz, 160Hz, 200Hz...ect Quote Link to comment Share on other sites More sharing options...
meade916 Posted June 16, 2011 Author Report Share Posted June 16, 2011 i cant speak for Skittles since he is an expert, but for me personally, my scope is now obsolete (for setting gains). If it didnt have a DMM built into it, i would probably never use it again since thats all i really use a scope for in my life anyway.

skittlesRgood Posted June 16, 2011 Report Share Posted June 16, 2011 (edited) an oscope still has its uses, this just isnt one of them anymore. its kinda like bag phones, they were pretty awesome when they were all you had for a mobile device, now theres new better things or the use. Its just how technology works. this is a neat new tool but its has NOT made the oscope obsolete by any means. i did an experiment a little while back you can try. tune your mids with a 1000hz tone until its just under clipping. now, at the same volume, play a 100-200hz tone. try it and see if you dont get clipping. i had a video of this but for some reason it got corrupted on photobucket but i could make one again. now if this thing had 40hz, 100hz, 500hz, and 5000hz. then it would replace my need for an oscope. and that would be nice, because my scope is large and needs to be plugged in. maybe the next version can have those? If you have your bass, treb, eqs, ect turned to zero like the instructions for the DD-1 indicate, then you don't need to test all of these frequencies. We did 40Hz and 1kHz so that we could do full range amplifier and subwoofer only amplifiers. in my test it was all flat. used a tone generator. i mentioned those frequencies so you can tune a 4way system. just my suggestion for what would make me interested in the product. i understand i am an odd market though and it may not be beneficial to appeal to that. maybe theres something i dont understand with what i did. thats always possible. i can make that video again and show it to you and you can tell me if i understand it correctly or not. i would just PM it to you. if you dont mind Edited June 16, 2011 by skittlesRgood Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

Crossovers don't add gain (unless someone really f'd up lol). Quote Link to comment Share on other sites More sharing options...
