Correctly setting gains

[Ninesvnsicks 10+ year member]

I'd like to set using voltage I just don't know how many watts to put in the formula because my sa-12's are rated for 600 watts but handle more.

Thanks, i'll probably just stick with the 0db tones then. would rather play it safe. And the DD-1 looks really nice but how much more would it get than just using a DMM? I really won't be doing this too many times so don't want to spend too much more than I need.

Its a huge improvement over the DMM

Maybe i'll consider one then. Would it be better than an oscilloscope? Because i've seen some of those for a bit cheaper.

I want a dd-1 but not at $150 f that.

Easier. and faster. Better then one of the cheap hand held scopes

$150 tho really? I understand its good but its just a distortion detector I was thinking it would be like 30-50.

I cant tell you how good my set up sounds now. Everything blends better. I dont even want to run full volume anymore but it can. I dont need to though

Everything comes on power when it supposed to

oh don't get me wrong I want one but $150 is too expensive for me.

Yeah I know how you feel. It's a little steep if I won't be using it much at all. Is there any major downside to a DMM? It'll be pretty close for the most part won't it? I want to get as much as possible without damaging anything but if it's only going to be a little bit more with a DD-1 I think I'll be alright.

It may be easier to use than an o-scope, but I wouldn't call it "better". Both a DMM and an o-scope allow the user to set their amps for specific power levels. The DMM requires some level of "faith" that the amp can do a given power level un-clipped, but the o-scope will allow someone to get as much un-clipped power as possible out of any source.

A permanent "real-time" clipping indicator would be nice to have somewhere within my view (one for source, processor, amp). Then I could set the gains at -3 or even -6. Older or poorly-recorded tracks could get full power and I could just use less volume knob on the better-recorded tracks.

I would say its "better" then the little hand held joints. Distortion is not only a clipped sine wave. Stuff you wont be able to make out on a very small screen

So just to be sure, the voltage I'll be looking for is 24.5 when the speaker impedance is 4 ohms and the rms rating for my bridged channel is 150 watts?
