I use the oscope first for a clean signal then Dmm and after listening I set by ear.Alright, what's everyone's preferred method for setting amp gains? O-Scope, DMM ?
Some of you trust your ears to set gains on your amps but not to determine differences in sound quality..........OK so that's how it works. Just wanted to get that straight.
Hi Mike. As an objective third party that just read through the above posts on gain setting and then your above comment in this thread, I have to wonder what your intentions are? Your post does not add anything to the discussion at hand, and frankly comes across as an attempt to troll for another sparring match.Some of you trust your ears to set gains on your amps but not to determine differences in sound quality..........OK so that's how it works.

That's where I was headed with this thread. I have also read some threads on here about performing the same method on amp gains as well. To do so on amp gains do you use a certain test tone to find when clipping occurs? Obviously the clipping point is audable but seems using an o-scope would be much more precice. My hearing certainly isn't what it used to beI do like to use an o-scope on RCA outs to know where my HU max clipping volume is, but otherwise I set max amp gains by ear.
If using amp gain to balance driver levels in an active install then REW comes into play.
I bought a SainSmart ARM NANO DSO201 earlier in the year. As I said above, it confirmed that my HU's internal amp clipped at the same exact volume level that my ears (with the aid of test tones) detected. Same pretty much held true with the front/rear preamps, though the way "I" tested such was by hooking the Scope to the amplifier's speaker terminals and dialed up the HU volume until clipping was detected, all while the amplifier gain was set to the minimum level.I have always used my ears as well but am entertaining purchasing a scope Like an Arm Nano 201 handheld scope. Anyone have any input on this device? Ebay item 200958043071
When you're you're tweaking the gains by ear and you hear a difference. that difference can be measured, difference in amplitude right? Now, when you set two amps to the same output and then switch back and forth between them and make a claim that one amp sounds warmer and the other more clinical, what you're saying is that the FR from the two amps is different. That's the only way you can hear a tonal difference, so that FR difference is measurable right?Some of you trust your ears to set gains on your amps but not to determine differences in sound quality..........OK so that's how it works.
