Setting gain on BC3500. Clipping or not?

Recommended Posts

Okay got the fluke oscilloscope hooked up to the amp..... waves show perfect curves @ 40hz.   the remote bass knob clipping light turns on at a certain point, yet the oscilloscope shows a nice perfect curve.  has anyone dealt with this amp before and had this issue?

I always set the gain by ear. Has never let me down. Between my 6 systems and the numerous times I've set te gain I have never blown a sub or had any failure. Same with me tuning all my friends systems. You just have to be smart and use your senses to identify the stress on the sub or subs.

biggest issue there is that the curve may be fine at the voltage you tested it at but once it dips lower that will change...

i was leaning on a 25hz tone for 30 seconds the other day, didnt fall below 13.4... running a mechman 300 amp alternator. 

 

should i take the warning from the remote bass knob and agree that its clipping?

 

or should i physically take the advice from the oscilloscope which shows perfect curves, no clipping?

clipping light isn't very accurate...

Clipping lights don't work.

Neither do cheap oscilloscopes.

Set your gain by ear.

Do it by ear man. Also, if you "did" want to use the knob, you would back down once it begins to flicker, not once it shows it first light, if you get what I mean. You kind of want it to flicker with the bass notes.

So easy by ears !
Hope I will never regret to do it like that, but I've never burnt any equipment so far ! And I'm not a specialist in tuning amps :)
