Once again I really don't understand much about solid state circuits and ICs and the such. So what do these little 8 pin thingies do? I imagine they are like tubes in that they can do a variety of things, and that you can swap different ICs to get a different sound, like swapping a 12AX7 for a 12AT7. I figure the 4558 is part of an amplifier. I googled 4558 and couldn't find much except people selling them.
The reason I ask, besides understanding, is that each module on my console has about several 4558dx, I don't have a schematic, but just by glancing at the PCB it looks like there are 3 on the EQ, one with the aux sends, and one by the bus assignments. I figure there is something out there that I can swap these out for to give me a sweeter sounding console. Some Burr Brown's or maybe even something discrete. I just remember someone once telling me to get rid of those 4558s.
Thanks
