First monoprice has the stuff. These splitters are perfect for splitting signals that you need no loss on. Very well made and have worked flawless. I used it for adding my third 1000 watt long throw 12in sub into my Atmos system. 98% of my cords are Monoprice
Happy to find what I needed including quick service at Monoprice.
I was looking for an unusual (to me) connector to test a new device I purchased. My order arrived, correct items, , and ahead of time. I recommend buying from this company, and keep their site on my favorites list. 6in RCA Female to 2x RCA Male Digital Coaxial Splitter Adapter. These appeared to be as good as or better than other such cables I've purchased in electronics stores locally.
