I've made an HiFi Audio Switch by myself. I've created the Alu-Plates with a CAD-Software and they where produced by a CNC-Company. I have assembled everything at home.
I haven't gone the cheap way, it was the way with best Quality of optical and technical Specs. There was nothing to buy with this Quality.
I have done ist because i had Loudspeakers from Nubert with a ATM Tuning-Module which must be connected between the Signal and the Amplifier and my Amplifier had no PreOut and MainIn.
Step 1: The Building of the Switch in Pictures.
Pictures are telling more than 1.000 words.
Step 2: Switch Is Selled a Few Month Ago.
Now i have selled the Switch, i bought a new Amplifier and build in a MainOut which wasn't there from Factory.
