Question on setting gains.. (didnt hear distortion)

[oneill584 10+ year member]

Hey guys,

I followed all the rules on setting my gains for my comps.

Only problem is, I didn't hear any distortion.

Amp is sending 75 to each speaker. Got myself a set of Image Dynamics comps-100 watts each.

I didn't hear any distortion. Is it supposed to be real clear? I did notice however, that when the gain is set about halfway on the amp, a little light flickers that says clipped. I'm guessing this means that the amp is sending a clipped signal, which in turn will blow my speakers. So i decided to turn the gain down to under the point where this clipped signal comes up till I hear from you guys.

Thanks,

Mark

When setting the gains you are supposed to slowly raise the gain untill you hear some distortion comming from the speakers.

I raised the gain almost all of the way probablly about 75%, and didn't hear any distortion at all. I did however notice a clipped signal alert on my amp when I cranked the gain more than halfway. I'm not sure if this is bad or not, so I decided to just turn it down for now because I do not want to blow out my speakers.

you must not know what real clean speakers sound like, or maybe you don't hear distortion for that reason

you might not notice the distortion if you set your gains high, but i'm sure if you turn the HU volume up just a litle more you will

true... thanks

you should certainly hear distortion, especially in mids/highs...its really obvious.

good stuff there, what amp and how many watts (RMS) are you running to the comps.

Amp is a pos.. I believe it is a Blaupunkt THA-275 Thin series?

Could be wrong on the model number, but im almost positive. Its a POS I know, just don't have the cash right now for a new one. It is pushing 75 to each speaker

your only giving them 3/4 of there rated power. that may be the reason you don't notice distortion. You should set your gains with a dmm or set the gain to about 50 percent. Don't go too high on the gains though. Those ID comps are begging for more power by the way.

Ya, honestly I feel liek and wish it was a little louder. My subs overpower it. Will I have any problems keeping the gains at 75%?

Do you seriously still not realize that where you set your gains is completely irrelevant

50 percent means nothing without context (ie. the strength of the preamp signal and the scale of that particular amp's gain knob)...

seriously now...

i know, i was just saying to do it that way if he didn't do it with the dmm. Most 2 volt preouts should be set to around 1/4 gain or so, so i just figured half gain was a decent guess.
