need opinions
Sunday, July 17, 2011 8:25 PM
Just wondering what your guys opinion on this was'
http://wccaraudio.com/distortion-detector/smd-distortion-detector-dd-1.html
its only $140 and it seems like it would be a good alternative to an oscilloscope to help me set my gains and tune my system. I'm not buying this because of Steve Meade i could care less about the guy, it just seems like a pretty good product to have and before i buy it i would like some opinions from people. Thanks.

its useless, dont buy it
you can use multimeter and with some simple calculations get the same result
$140 is not worth it imo

This. If you're not competing, I'd say that's $140 you can put toward a better system.
Either do it roughly with a DMM or do it by ear. Preferably the latter.

Thanks, the only thing im afraid of if i do it by ear is that I honestly don't know what a speaker sounds like when its clipped and all the music I listen to is on my iPod which some songs are crappy quality so i cant tell if its distortion or just bad quality. I would just feel better if I had something tell me I wasn't clipping or distorting my speakers other then solely rely off my ears.

Then definitely do what andrey suggested the first time.

Have a DMM? If not, their like $10 or something at Harbor Freight. Then do the following:


The chart's VERY rough but should give you peace of mind at least.
Caveat to this method is that you will almost certainly distort if you turn the HU volume any higher than the 75% you tuned it at. So no more full-blast.

first thing id do is dump all your poor quality songs. whats the point of a nice system if your playing junk music thru it. one thing i never got about the whole compressed music deal. great you have 10,000 songs. but the sound bad.
