Often need to mix two preamps together in a very simple way (equal gains, or one at -3 to 9dB).
Would like to experiment with doing this without adding a seperate mixer to the setup. Thinking of adding 'bus jacks' to two M-Audio Duos (orig, not M-Track Duo), to use a linking cable to connect the two at the 5532 inverters that follow the INA163 pres. Essentially using the inverters as virtual ground summing amps (never more than two pre outs would be linked to this point). Would the 3.2k between summing point and each INA provide sufficient isolation between their outputs?
Actual values from the Duo are shown.
See any issues with doing this?
