Greetings,
I need to take 4 audio inputs from 4 separate (low power) MP3 players and combine then so they will all play off a single set of desktop computer speakers.
ganging all the inputs right now lowers the output and the distortion increases for each input added.
I have been told a "Summing Amp" will work, but I cant find one that is low votage (under 12Vdc)
Will I need to isolate each input ( diode? ) prevent and back-feeding into the other units?
Anyone have a diagram that might work?
Cheers
Steve
