im trying to figure out how to get past these pre's in my ada8000, and i need some help!
kev provided me with this info, but im a bit unclear, on jakobs schematic it appears that the AD convertors are the tl074 chips, while in the al1101.pdf located below, it says ITS the AD convertor. which one is it? there are only 4 al1101 chips, but 8 tl074's, there are alos 4 al1201 (i think thats the right number) so im guessing thats the sister DA convertor chip.

he said that it shouldnt be a problem to inject unbal into the tl074, but me being a moderate noob, and not wanting to mess anything up i'm double checking.
as in inject a hot pre'd signal DIRECTLY to the leg of the chip?
these frickin chips are so small and ive never soldered chips this small or board mount resistors and caps. how much do i have to worry about frying the chip by overheating?
thanks for any help. i really hope i can get this to work. i need alot of ch of AD but i cant go out and pay 1500$ for 2ch of apogee or anything else right now :?
thanks.
