FiManic Posted January 27, 2015 Report Posted January 27, 2015 I've searched this forum and google to find a legitimate answer, but only come up with the same quotations listed in the owners manual. "Peak light displays when the amplifier is reaching peak power output, light should only flash briefly, and for no longer than 2-3 seconds at a time" My question is: Is this a clip light? A pre clip light? Or exactly what is claims to be? "Showing when amp is near peak output" (which sounds like pre clip or clip, to me) I've done a ton of reading and research while installing this system and this is the last thing left to give me complete peace of mind. Short story: sub is getting hot after short playing time. (Fi bl 15 fully loaded) Long story: can be elaborated if some one wants to get that deep into it.
SIDE SHOW Posted January 27, 2015 Report Posted January 27, 2015 keep an eye on it and set your gains correctly..... you may have your gain too high. to what you are asking, I don't have the answer as I have no experience with that specific amp
FiManic Posted January 27, 2015 Author Report Posted January 27, 2015 Yes, I've followed the manual, I've looked up pre amp output on my HU and matched it as closely as I can imagine, to the amp "level" adjustment. and compared db levels and subsonic frequencies to the sub and amp. I've set it all up pretty well. (I think) from what I've read it says to run the amp so that the "peak" light indicator flashes on and off briefly at hi volume. But! If this "peak" light is in fact a clip light, obviously I don't want to be running it at such a level that it clips my sub at high listening levels. If it is a clip light obviously I would want to tone it down until the light doesn't come on. If it's just a visual indication that I'm achieving max power WITH OUT clipping, then obviously I would like to keep it where it is.
SIDE SHOW Posted January 27, 2015 Report Posted January 27, 2015 try do a search on this forum on how to correctly set gains..... just to make sure everything is set up correctly
FiManic Posted January 27, 2015 Author Report Posted January 27, 2015 The sub getting hot, is not necessarily what I'm looking to discover here. I'm pretty sure I know why it's getting warm, I just don't want to admit it. Because I don't want to have to do the big 3 and add a secondary battery. I'm mainly concerned with the true meaning of this "peak" light. I've seen Phoenix gold reply to a few posts on this forum. Maybe eventually they (or some one educated in their components) will chime in. Or I will just have to track down an oscilloscope.
reedal Posted January 27, 2015 Report Posted January 27, 2015 I would say more than likely if it was a clip light they would advertise it as so. They say it's a peak light in their manual so that would make sense that that is what it is correct? (Because companies never lie about their products) Either way, you should have your gain set correct (no guessing) with the proper tool. Oscope being the best way because you can see the signal when it starts to distort or clip. And don't worry so much about that little light afterwards because you set your amplifier up properly, and as long as you're sending it clean signals it will reproduce them at a stronger level to the best of its ability.

When you put it like that it makes so much more sense! Lol. I do like that approach, and I guess I should probably start my search for an oscope. Fun fact: none of the audio stores in my city use an o-scope. Which is why I was forced to set gains by myself. One shop even said " we charge $35 to tune amps. we just turn the gain all the way up, and back it off 1/4 of a turn, or until it doesn't sound distorted anymore"
FiManic Posted January 27, 2015 Author Report Posted January 27, 2015 And thanks for the advice guys. I will just need to find a reputable sound shop in the Sacramento area, to tune it properly.
