An eye opener

This quad ballun really does the job. I used it with 25m of cat6 cable. But when testing (still coiled) I picked up some hum. So I modified it by soldering a ground wire on the casing of the internal RJ45 female connector in on of the 2 boxes. Perfect sound now !

I will also solder myself some balanced cinch-XLR cables (pin 1 unconnected), so that I can send microphone signals through this wiring.

saved my life

i used it for long distance (120m) installation audio transfer and it does what it claims nicely.

will buy again.

Very useful for large venue

Very useful and cheap device! When you have a large venue and have any audio cables or their installment is improper i.e. because of their lenght this balun is the only salvation!

Handy little boxes

Nice sturdy build quality. These were a great solution for me. I'm using these to get extra returns down a single cat5 run for 2 stereo IEMs - going from a console into a Samson S-phone headphone amp to drive Fischer beltpacks in stereo. Unbalanced input on the headphone amp, but these boxes give me a balanced run, and eliminated problems I had with lighting dimmer buzz.
