New way to check for clipping with DMM possibly?


Recommended Posts

isn't clipping DC voltage?

If your amp is putting out dc voltage you might have bigger problems than clipping

i didn't mean nothing but straight dc voltage. I always thought that when the ac waveform flattens out, that represented small amount of dc voltage. googlesearched and apparently I was misinformed.

God damn its hot today. My balls are stuck to my leg.

Your speaker wires going to your speakers carry AC (alternating current) electricity, there is phase, not polarity. The electricity is alternating from positive to negative, thus causing the voice coil to move inward and outward.

So I believe your theory about using a dmm to check for clipping does not work. :peepwall:

It was pouring rain here today so I couldn't test it out on my truck but my home system does not go negative on the meter. Hopefully its nice so I can check again tomorrow. I just figured I'd throw it out there to you guys and see theoretically what was happening.

My guess is this. It really depends on the refresh rate of either your dmm or the dmm display but I am guessing you dmm only shows a single polarity your are clipping pretty badly. If you clip a signal bad enough you are effectively sending a DC signal to your speakers.

what setting was your DMM on?

AC voltage changes phase from + to -, thats why its AC. So it really shouldnt work that way.
