Rogers Posted May 21, 2009 Report Share Posted May 21, 2009 enlighten me on how you will get the average of ac voltage, when your multimeter is set to dc voltage?A cars electrical system is DC current (direct current), your amplifier takes dc voltage, and turns it into ac voltage (alternating current) which is what powers your speakers. After you properly set your gain using the ac voltage chart and flip your dmm to dc current (which is distortion and or clipping) will tell you. If you have any dc current being displayed that means to turn your gain and or bassboost down. Ive done this for years before having a oscope. huh....wow... i didnt know that.... so i have a question.... not to thread jack or anything... but im sure we have all seen the elimental designs tutorial on setting gains with a dmm.... anyways his dmm shows the waves... wouldnt that replace the need for an oscope?.....

His 'dmm' is probably what's known as a scopemeter. They cost... a bundle Normal dmm's don't show the waves. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
