The SW4 Stereo Input/Output Switching Control
Goldpoint SW4
Need to select more music sources than your amplifier has input connectors for? 
Here is your solution. The Goldpoint SW4 is also handy on any audio test/compare bench. 
The SW4 was originally designed to provide additional Input selection for an amplifier which only had one set of stereo Input RCA jacks. However, it's reversable, so you could use it to send one Input set out to four different amplifiers.
Selector Switch: Goldpoint 2P-4T-1D   (This rear panel is the same one used on our SA4 Passive Preamp.)
AUX Input can be easily rewired (two internal wire jumpers) for an alternate functions: 
     1) Fourth Line Input (factory default).
     2) Tape Output.
     3) Main Output #2.
(Alternatively, the SW4 can also be used in reverse: One stereo Input can be sent to any of four stereo Outputs. In this case, the "Main Out" becomes the Input, and all Line Ins (1 through 4) would be used as Outputs.)
Wiring:  High grade, silver-plated copper, multi-stranded, with Teflon jacketing.
Rear Panel RCA Jacks:  Gold-plated, heavy duty solid brass, right angle PC board style. 
Chassis:  Aluminium clam-shell, 1/4" front and rear panels.
Dimensions:   2.3" Tall  x  6.2" Wide  x  7.0" Long
Weight: approx.: 1 1/4 lb.
