    Question Unbalanced signal to balanced input scanners

    Can you feed a normal scanner set an unbalanced signal?> I have not been able to locate my GS120's that I put in a very special place. So I am curious if I can use just a regular scanner set and drivers?

    Thanks

    You will just need to ground one terminal of each scanner amp to pin 25

    It might shock you to know that ILDA once published "preferred" circuits as the part of the standard.

    This is the preferred ILDA driver for single ended to DIFF, redrawn from the 1985 version of the standard, which came as almost 90 pages in a nifty three ring binder.

    Pin 25 might be hard to find on this
