This product allowed me to move my subwoofers to another part of my theater room where I had an unused Category 5 cable and I had a loud 60Hz hum coming from the speaker cable that was there. I also soldered the RCA connector directly to the Cat 5 cable, which didn't work either as it picked up the loud 60Hz hum. Using this product eliminated the 60Hz hum in the subwoofers and allowed me to place up to 2 subwoofers in my theater (with right/red and left/white RCA connectors) for 2 different channels.
