I have an old telephone switchboard with standard 1/4'' TRS connectors that I am planning to rewire for use with my many many many guitar effect pedals and recorders and things. The switchboard has 4 panels, each panel has two rows of 26 jacks.
Let the 'o' be jacks and the '|' symbols are not there they are just imaginary to help group what I plan to do. I was planning on wiring the panel like this:
___________________________________________
[ 1 2 3 4 5
[ o o | o o o | o o | o o o | o o o o o ...
[ o o | o o o | o o | o o o | o o o o o ...
[___________________________________________
IN1 | OUT1 | IN2 | OUT2 | etc ...
so that the first four jacks (columns 1 and 2) have six outputs (columns 3 4 5) and this process will be repeated for the next group of 5 columns until there is a single column which I am not going to worry about. These in/out groups will all be separate from one another.
Now these are simple normally closed jacks with only the signal and ground leads. How exactly do I wire this? At first I assumed that I wire all the outs in series and all the ins in series and then throw a diode in there connecting the ins and outs. But then I realized that after a couple of gain stages I will get some wicked distortion from that diode and I need my audio fidelity.
Maybe I am just over-thinking this. Any help guys? I desire to learn!
