I understand the Null Mod, but the Null control on my 9748 appears to do nothing... Anyone have some insight into this?
There is a trick to tuning these knobs in properly. You can start by centering both knobs, applying a signal to just one input and tuning the other one until the sound dissappears. Then swap inputs but don't touch the first pot you tweaked, just turn the second one until the sound again dissappears. At this point you are nulled and should have a balanced
modulator as opposed to an unbalanced
one (where the original signals come through as well as the sum and difference). I'll have to get a module in front of me if you need me to expand further, but this is the basic idea.
