I am getting +20 dB gain out of the Smixer2x1 Module. I have the two input gains at -6 dB each, expecting them to sum to 0 dB and am getting +20 dB out. Am I misunderstanding the function of this module?
You're seeing this +20 dB gain because the variables gain1 and gain2 are linear, not in dB. Looking at the help file for this module, the only hint that the gains are linear is the 'units' field in the properties section. I will update the documentation for this module to make it more obvious that the gains are not dB.
Thanks for revealing this gap in our documentation!
