I'm designing a variation of my pre filter mixer using the CH446Q 8x16 crosspoint switch, and while doing so I started wondering if having the switch after the mix input resistor was a good thing or not.
Douglas Self to the rescue, seems that switching directly to the virtual ground of the mixer summer is the way to go.
