The "frying egg" is a commonly known problem withe sample rate converter chip used in the DCX2496, the CS8420.. There are many many mods to the DCX that gets rid of this problem by replacing this chip.. My complete set of mods to the DCX2496 incorporates a replacement clock/src module which involves removing the CS8420 and replacing with CS8416.. Not only is the fying egg issue fixed,, but the improvement to the sound is huge (along with the other mods too)!!Well, got a brand new DCX2496 and got it set up. Turns out I got one with the 'frying bacon' noise. Anyone found a reliable fix for this, or will i have to return it and pray they fix it?
Hmmm,, that's interesting..Then why is it only one channel out of the six?
I'm not sure what you're saying when you explain that the problems come in due to a 40Hz signal being reproduced as something other than 40Hz? 40Hz is 40Hz, it's the representation of an AC signal that oscillates the cone of the speaker so it moves 40 times per second to produce a 40Hz tone. The cone cannot move more or less times since the wave is limiting the movement in the magnetic flux created in the pole gap where the coil resides.I am thinking that certain frequencies of the multiple subs may very well not match, other than getting the subs themselves level matched with broad band pink noise. If one is producing a 40Hz signal at 90db and the other is producing a 40Hz signal at 100db and you have a combined peak at 40Hz, after eq'ing that combined peak, it makes sense that there will still be the same variance between the two subs at that 40Hz frequency. The eq has no idea which sub to reduce it from... it is reducing the combined signal sent to the subs, therefore both subs get the same cut or boost. Hearing a louder tone out of one over the other would be natural in many cases for varying frequencies... some higher in one, some higher in the other, but that should not ultimately matter since we don't play one or the other, we play both or all and look for the combined response at the listening position.
There have also been several here with various rooms who ended up only being able to eq them combined.
Actually I would think symmetrically located subs in a symmetrical room would be the easiest to equalize separately. They both should have the same response with all things being equal. I don't know... maybe my thinking is skewed. :huh:
It just seems nearly impossible to eq one sub by itself, then eq another by itself in a different location, and then combine them for an acceptable response, regardless of the room. When those signals interact, there will most likely always be some drastic effects to the response. I won't say there are not exceptions, but I would say they are very rare. :dumbcrazy:
