Handy little boxes

NyquistAudio 24.09.2018

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.

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.
