Nothing complicated about it. It's simply a bigger version of a 'Y' cable adaptor. Mount several jacks on a rack plate or a box. Connect all of the 'tip' terminals together. Connect all of the 'sleeve' terminals together. Now, any cable you plug in will be connected to any other cable you plug in. So, one cable coming from your guitar, pedal-board, or whatever, and one cable out to each of your amps.

Amps with multiple input jacks, like some 'four hole' Marshalls, allow you to drive both channels at once by plugging a cable from your guitar into one channel, and running a short jumper cable from the other jack for that channel to one of the jacks for the other channel. Since that leaves one jack for the second channel unused, you can run a cable from there to the input of another amp, with no need for an adaptor cable or a junction box.
