DIY Rack Patch Panel Q

#1 Post by jimbo7 » Fri Sep 06, 2019 6:40 pm

I just got all the parts in to make my 8 connector patch panel for my main rack. I'll be using speakons and xlr's first then add power connectors later. My question is, should I wire the speakon patch cables with 14ga dual-conductor shielded cable or use 12ga single-conductor wire (and then twist the 2 wires and cover with sheathing)? The patch cables will be no longer than 2 feet.

Speaker wire is not shielded. For inside the rack you can use 14ga install wire for short distances like that. Install cable has a thin vinyl cover as opposed to the thick rubber on regular speaker cable. That's what's in all the racks I've built.

Same with your xlr connections. Use 22 or 24ga. shielded two conductor with a drain (ground) install cable. It's usually gray or white.

The reason to use install cable is that it's easier to work with inside a rack and doesn't take nearly as much space with you bundle the cables.

Here's an example....

That's what I do although 14 ga would also be fine. Techflex if my favorite sheathing, not really necessary in a rack but looks really nice. Easiest way to twist cables is to chuck one end of your cable pair in a drill, hold the two cables about a foot away from the drill, then squeeze the trigger while holding the pair from the other end. Slide your hand down to the other end as they get tight. Nice and even and tight.

I like using the cast silver metal panel mounts, I find them easier to see in the dark to find the holes.
