Xlr to rca
Hello, I am trying to hook up a large bgm model 620 b pro amp to my stereo, it only has 1/4" jacks, it was given to me with an 1/4" to rca 1.5m cable, I've tried hooking this up to a luxman stereo reciever and to a McCormack tlc-1 pre amp both of which have two sets of pre outs, I cannot have the outs connected to my velodyne hts15 sub and to the bfn amp at same time without mad hum, if I disconnect the sub or the bmg rca either one all the hum goes away the hum is present in both the main speakers on bgm and in the sub, the cable is wired from center pole of 1/4" to center pole of rca I was wondering if there is a pole difference between old pro audio and home audio, should I flip it so it center pole to outer and vise versa? I've tried various grounding options with no luck, but it sounds like a ground loop. Any thoughts on how to fix?

Please take a look at this reference: http://www.rane.com/note110.html I had a ground loop problem with my pro audio stereo line mixer until I figured out that pro audio equipment is typically wired as "floating ground". This means that certain cables need to have the ground/shield disconnected, especially if you are going between 1/4" TRS and RCA connectors. |
Buy a wireless transmitter/receiver kit for your subwoofer. They work well and aren't very expensive. Here are a couple that might work for you. https://www.bestbuy.com/site/rocketfish-wireless-subwoofer-transmitter-receiver-kit-black/6965266.p?... https://www.amazon.com/Wireless-Transmitter-Receiver-Subwoofers-Surround/dp/B00SJ49ZJQ |
