Hi all,
I am creating an audio splitter/combiner unit with multiple inputs, outputs, stereo to mono, switched, etc. Attached is a schematic.
I used a bit of information from here in my design.
https://www.rane.com/note109.htmlNow I am on to PCB layout. The only issue I have, (note: this will not have high production volumes, maybe a sample set of 5) is doing single or double layer board. Because this is audio, I need to be aware of trace distances and maybe some coupling? Especially with a 2 layer board? Obviously interference and audio quality would make a difference here and is important. I can route with a single layer but the rotary switches definitely provide a challenge in that routing. Double layer would be much, much easier but again I am concerned with coupling. Any design rules to follow or suggestions would be appreciated. Thanks!
