Multiple inputs for single output

tommy_o · 28th October 2009, 01:13 AM

Hey everyone, sorry for the simple question that surely has been answered before. I searched but couldn't find the answer.

I have a great old amp that I would like to use about 3 devices on, but unfortunately there is only a single aux. input. Any advice on what I can use to add a couple more inputs? If the solution is a simple (emphasize simple) DIY solution then I'd love to do that since I'm trying to get my feet wet making my own electronics gear.

Otherwise, what is the name of the type of device I'm searching for?

I truly apologize, I'm very new to audio electronics. Thank you!

I have a similar need. My question is, can someone recommend a selector switch (even better, a mouser part #)?

Also, can I just solder/connect the ground from all inputs to the ground of the output jack, or do they need to go through the selector switch, too?

Try an Adcom SLC 505? (straight line controller aka passive pre-amp).
They go for about $50-75 on eBay. It will serve as the switch for the various inputs and it will go to your Aux input. Use a short interconnect.

Thanks, but I'm really looking to DIY... It will give me more flexibility to get something that fit me need exactly.
