[sdiy]RE: [sdiy] Using BA3812L in a module

[rdrake]

i picked up a few of these recently, to try a small 5band eq.  the way i read the data sheet, it looks like their performance measurements were based on typical home stereo values... but, for instance, they don't spec a value for max volt out...  if it has issues, i was going to add a simple divider/booster, a'la ken stones stomp box adapter (http://www.cgs.synth.net/modules/cgs60_sba.html).
