Basic question re: empty spot on input/output selector

I'm putting together a single-ended and balanced selector switch (it's basically two separate switches in one chassis). There are five possible outputs however only four are being used and there is no mechanical method of reducing the possible positions in these selectors. Should I be placing a 10K ohm or so resistor across ground and signal on the unbalanced side, and anything on the balanced side so there is some dummy input impedance? ...or should they just be left empty.

Thanks very much for any suggestions!
 
Depends on the manufacturer. Some older models had an additional plate with little tabs, any one of which could be bent down to block off extra positions. But that was back when practically all multi-position switches were open-frame.

There little to be gained by adding the extra parts. If the input seeing the selection (connected to the wiper) is capacitively coupled, you might want to have the unused input(s) grounded.

Or, if you have enough space on the back panel, why not just add one more line/aux input? *future expansion* or whatnot ..

Cheers
 
Hi Rick, thanks, yeah used plenty of those, unfortunately the feature isn't on these Grayhills. Completely out of space on the back unfortunately.

Thanks for the suggestion Rayma, I appreciate it. Should the + and - balanced outputs be referencing the chassis ground at 100 ohms?

Thanks gents, very helpful! 😀
