For Cutoff on the Potentiometer boards, I get: -5V - 5V (Cutoff 0 to 10), and -4.36V - -3.74V on the data pin.

Pin 1 is not connected on the MC1408 and does not need to be connected on the DAC08 either. All other pins are used. ________________________________ From:

Hi, I was suggesting that you set the other pots all to 0volts, which would be the middle position, not the -5V position. But it sounds like the mux
