So after setting my subwoofer amp (FX-2600) to 800 watts using the frequency generator app for phone (I play mainly through bluetooth), which was recommended on here, I had bass galore and even thought it was a little too loud. Last night, after listening at quite loud volumes for 15-20 minutes, I began to smell my subs. No bueno! So I did a little more digging, researching, etc and came upon using Audacity to check songs for clipping, recording levels, etc. I use Google Music Play for most of my stuff, so it "should" be good quality.
I made recordings of my most severe bassy songs and checked em out. What's most odd is none of them had clipping. I guess that's a good thing, but in one case I just don't understand. Anyway, if what I have been told holds true, the frequency generator is about -10dB. Most of my offending songs max out at -5. Not so bad. A couple go up to -1. One song, however, goes up to +3dB! And yes, this is the song which I don't understand how it has no clipping. That makes no sense at all!
So, I guess my first question....is this a good way to check to see where I should be setting gains? The majority of my music I have checked so far comes in right around -8 to -10dB, so I was figuring if I could set gains to that area I could then use the remote to turn the gain down on the songs which have -5 and above so I don't send too much to my subs. Is that another alternative?
See, I did a little test. I played the 50Hz test tone from the app and my amp is still set at 800 watts. When I played a 0dB tone at the same volume, I got around 60 volts....or 3600 watts! I have been over-juicing the hell out of my poor HDS208's during those brief moments of heavy bass. Granted, I don't think the 2600 can quite get that many watts on dynamic, but if I remember right, the dyno came close. But ouch!! No wonder I could smell em!
