imma genius. so **** it!
hehe, i dont know that i was using the corret terminology, its just what i call it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i know now, check the edit of post 7 //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifClipping IS NOT DC, it's still oscillating, so it's AC. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Me either. But I'm aslo not half as knowledgable as some of you guys on here.//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gifI don't think I've ever heard the term "power compression" used in reference to an amplifier before.
But the essence of what Hoss is saying is right.....eventually you'll reach the rail voltage of your amplifier and the voltage will cease to increase any further.
I certainly would not use this as a method by which to set gains or determine the level of acceptable distortion, however.
Already been covered.Clipping IS NOT DC, it's still oscillating, so it's AC. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Either by ear, or with an O-scope.well currently i just use the standard dmm, test tone procedure as i dont have access to an oscilloscope anymore.
i was just trying see if there was maybe a different, and better, way of going about it.
yup, i remember that thread.Either by ear, or with an O-scope.
Those are pretty much the only options currently.
You could also try using different level test tones (0db, -3db, -6db, etc) & the DMM method.
thch on here a year or so ago was thinking about making a little project that would have an LED light bar denoted with levels of "distortion" (1%, 10%, etc) IIRC......don't know what ever came of it though.
That method assumes that the amplifier is capable of exactly it's rated power.If you exceed that output voltage you will clip the amp.
The output voltage = (RMSxOhms)**0.5 or square root (RMSxOhms):
