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

[Jim Brown-10]

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.

I make all my audio cables out of plain old CAT5 cable (be sure to use
the stranded variety). The stuff's a real bargain, and the twisted pair
construction makes it a great choice around RF. I picked up a 100 meter
spool in eBay for around $30. I either don't use the spare pairs or
double 'em up, depending on the capacity of the connector terminals. I
use mostly Rean connectors, available from Mouser, for my audio cables.
They're good quality and you can get shells that take larger diameter
cable if needed for the 1/4" and 3.5mm plugs.
