Input limited


Setting up my Pioneer SX-1050. In the 70s all you had for other inputs was tape. Unit has Tape1, Tape2 and Aux. 

I also have CD and a Squeezebox. Both line level. 
So, how do I jam 2 inputs into the Aux? A plain RCA A-B switch box?

Well 1 in and  4 out with a rotor switch is gonna be the safest. Can't hit two sources at one time and reverse the way it goes into the pre.
1 out 4 in.. on a rotor switch.. PE sell them I'm sure

I Use a Goldpoint switch which works perfect for my application.  Perhaps it will suffice for yours also.  Scroll to the bottom of the home page for various box options.

Not out of inputs, just use the tape plays, same line in, different names. Pioneer NEVER had tape head. Just put labels over them.
