[Elecraft] FW: [OT] Headphone Splitter - Not The Kind You May Be Thinking

[Jim Brown]

I use miniature coax for 2-conductor (center plus shield) audiopatch 
cables, but you'd never fit four of them into the common plug (for 
combining two stereo circuits). A better solution would be some of the 
specialty miniature shielded twisted pair cable that companies like 
Belden make for portable use with microphones. It IS possible to 
shoehorn two of them into a Switchcraft plug.

BUT -- Bob, K4TAX is right about it being a really bad idea to tie 
output stages together. While they are probably protected by series 
resistance (good designers do that so when folks do dumb stuff the 
output stages don't fry), the resistance will also lose a lot of signal.

I do NOT recommend Behringer products -- in the pro audio world they 
have earned a really bad reputation for lousy build quality, poor 
support, and ethics.  The good brands (and companies) making good stuff 
for this kind of application are Rane, Mackie, and Radio Design Labs 
(RDL). Look for their products on their websites, then chase down used 
items on the usual places.
