Hi All,
I'm looking for a digital switch for a mic/line pre-amp that will be used to control the parameters shown in the attached schematic:
- 20db pad
- Phase invert
- +48V phantom power
- Mic/Line selection
The CD4066 seems to be a classic device, in that it was used in a lot of older designs for switching purposes, but from what I can see online there seem to be better ICs that have come along since then. I'm wondering if there's a common switch used in modern designs, that has less THD, noise, etc., and is used in mic-level or instrument-level designs. Yes, I know traditional switches and relays dont have the problems that digital switches do, but all-digital is part of the design/challenge!
I don't have much knowledge on the subject of THD, so any advice would also be greatly appreciated!
