February 25, 201213 yr Author Log in peeps. I know your out thereThere is a thread on this forum on how to do it. Are some of you saying it it totally wrong?
February 25, 201213 yr There is a thread to do this. It's not wrong, it's just not optimum. With that method you set the gain for that one tone; since music is so darn dynamic it doesn't make an sense to tune just for one tone, no?

February 25, 201213 yr I don't know why people make such a big deal out of gain setting.Its really quite simple.Unless you are just dumb its pretty hard to blow a well made sub.

I am just trying to get a point to start at and adjust from there.
February 25, 201213 yr OKay my phone just made a mess out of that.I hit post but it didnt show as posted so I hit again, same thing. Gave up on the lap top now.Maybe its just new, but I am not liking this upgrade so far.< all this facebook twitter youtube crap needs to go while I am throwing a fit.
February 25, 201213 yr You could do that. The only problem i could see happening is that from the start you're going to be trying to set it at the max rms. The first song you play may very well go beyond that and possibly start to strain your equipment. As long as your smart with it I don't see any problems to occur, as long as your on top of what's going on.

It glitches out here and there for me as well. Don't really see the function of the FB and twitter stuff on the left..

Generally a -6db or so test tone will provide good results. Most people will probably not be happy with the results from a 0db test tone as that's rather conservative.
February 25, 201213 yr Ok so i have one questionsay your gain should be set at 24, now how much under & over can you go and still be good playing / not clipping amp?
February 25, 201213 yr Ok so i have one questionsay your gain should be set at 24, now how much under & over can you go and still be good playing / not clipping amp?I don't know of any gain that has a setting of "24". The input sensitivity ("gain") is a range of voltages, not a numerical range like a volume setting, and that range is determined by the design of the amplifier. Where the input sensitivity needs set is based on the input voltage of the preamp signal. For example, the range of input sensitivity would be .2V - 8V. The gain would be set somewhere in that range based on the level of the input signal.Anyways, you can set the gain as low as you want. Being too low doesn't hurt anything, you are just not receiving all of the output power capabilities of the amplifier. Getting "close enough" is good enough because under most circumstances you are not going to hear a 25% difference in power (in reality the percentage can be higher, I'm just trying to keep it simple here for you). So if you set the gain too "low" and undershoot power output by 25% you are not going to know because you are not going to hear a difference.As for setting the gain too "high", you are safe for a while. A little clipping isn't going to hurt anything. Clipping is a little worse on speakers than subs because it will probably end up being more audible, but it probably won't hurt anything unless you are already pushing the drivers thermal or mechanical limitations (which is the only time a loudspeaker is damaged). Clipping in and of itself doesn't hurt anything, other than possibly making things sound worse because of the added distortion. A driver, any driver, is only damaged when it's thermal or mechanical limits are exceed. Clipping may be the reason the driver's thermal or mechanical limits are exceeded, as a clipped signal contains more average power over time than a pure sinewave. But it's the increase in power as a result of clipping, not the shape of the waveform or the "clipping" of the signal itself that does the damage.This is why people recommend just setting the gain by ear. Small differences in either direction aren't going to matter. Set the gain a little too low and you won't hear a difference because realistically you need a substantial difference in power to actually hear the difference. Set the gain a little high and the small amount of clipping isn't going to damage anything....with speakers it might sound worse because of the distortion, but generally with subs the clipping won't really be audible. Now obviously you don't want to completely overshoot the gain setting because it is possible to start damaging equipment if you run into heavy clipping and you are exceeding the driver's thermal/mechanical limits. But you need to be really far off and/or running unnecessary bass boost/etc before you reach this territory.If you are absolutely lost, the DMM method is a good place to start and tune the gain from there.
February 25, 201213 yr Alright that helps alot. Thanks! Got everything hooked up finally. Boy was that a painTime to set some crossovers and gains ! Thanks
