How can I connect one control board to two filters so that I can switch between the filters? Can someone point me in the right direction? Rotary switch of some kind? Is this even a good idea?
Id recommend a bunch (3) of 4053 switches for 2 filters or 6 of the 4051 for up to 8(eight) filters. A physical switch is not quite perfect as it might produce nasty transients on the lines when switching. No good Idea if you have a precious CEM3379 or even a CEM3399 melted with 300W Iron directly into your personal board
As pichenettes pointed out somwhere else (im to lazy to search…) you could also just parallel all Power Rails and simply connect the Filters with Y-Cables to the DIgital Board although i’d recommend the 405x version.
The best way is to simply assemble a 2nd DigitalBoard. Thats the way i do it . . .
Yes dnigrin. Does it work???
Haven’t gotten around to trying…
