I use this with female version of the product, to create a 4 universe multicore over cat5 for my titan mobile. great product incredibly handy! two very important points though, you must use shielded cat5 cable, and if you intend on using it for sound bare in mind it doesn't pass +48v. However using it for it's intended purpose (to send dmx) works great, as long as you're using a shielded cable!
