Markous Posted January 6, 2018 Report Share Posted January 6, 2018 Maybe using this video played on your phone through BT or aux would give you an example of what to listen for? Probably would have to play it that loud either. I would trust it if it's a reputable brand. IMO the benefit gained from trying to get a few more watts by trying to use dyno numbers would be negligible to the ear in a mobile environment.

SkarredSierra Posted January 6, 2018 Report Share Posted January 6, 2018 You cannot properly set gains with a dmm. If u dont have an o scope or dd1 u might as well be setting it by ear. Link to comment Share on other sites More sharing options...

Also..id love to see someone set by dmm with the same db test tone and then set by oscope and set by dd1 all with same test tone and see how far off the each method is from one another.. Im betting they will all be very close in range from one another. Like for example they all end up being around 12 oclock position minus a pinch here or there for each method.. Id be suprised if they are all very off from one another like 12 oclock 1oclock 2clock... Im sure someone has done this experiement already..

bcbrassard Posted January 6, 2018 Report Share Posted January 6, 2018 I trust the DD-1. Bought one years ago when they first came out. I knew it would be THE tool for setting up systems, Well worth the $150. I have a shit ton of money in systems so whats another $150. Link to comment Share on other sites More sharing options...

You simply cannot use a DMM to set gains. You can guess and get just as good of results (wrong). Don't forget, it isn't just about "my 3,000 watt amp will put out 3,000 watts if i use this formula". You need to know when the head unit is distorting or at the very least, clipping. Then you need to know if or when any crossovers or EQ's (or otherwise processor) in the chain before the amp itself it clipping or distorting. If you don't know any of that, you are wasting your time. Good luck doing that with your ears at the pre-amp (RCA) level. Good luck doing that without an O-scope in the very least. That whole "turn your head unit up 3/4 of the way" thing is such bullshit LOL! That bass knob you love? Oh ya, you will need to know when that is distorting or clipping. Then you have gain overlaps. Again, good luck doing that with a DMM or the ear-o-meter. All SMD products + MORE available at my store here! https://wccaraudio.com/ Subscribe to My Youtube Channel!

SkarredSierra Posted January 6, 2018 Report Share Posted January 6, 2018 A dd1 or oscope goes off distortion. Sure u can set it with dmm and it may only b a little off but that little could be causing lots of distortion wich could cause equipment failure.

So if my deck plays clean till 38 out of 40 then i set the mono amp gain at 38. Versus the 3/4 volume rule. I was told by some that the benefit of setting gin at 3/4 volume over the max volume before clipping is that the 3/4 method will allow me more headroom for poorly recorded and/or low volume tracks Link to comment Share on other sites More sharing options...
Markous Posted January 7, 2018 Report Share Posted January 7, 2018 You use the DD-1 on the rca out's of the source to finds it's max clean level, then on the speaker outs of your amps to set the gain to a clean max level. That's what i did, hope i read the manual right LOL! reading comprehension isn't my strongest suit.

Question however..if you set your gain to the decks max clean level..what do u do when a track that is recorded on low volume comes on or that has a bassline thats like 14db? For those tracks you would want to pump the volume up more but since you are already near max volume on the deck (some decks can go 50 out of 50) you wont be able to amd they will forever remain soft.
