ekbriggs Posted May 14, 2004 Share Posted May 14, 2004 while i was playing around with my system today i was playing around with my amp settings and noticed an ever so slight hum coming from my big velo fsr-18. When i turned the volume on its amp all the way up the hum got pretty noticeable (i only listen at 2-3 out of 10 so i had to have my head pretty close to it to hear anything) from around 4-5 feet away in a dead quiet room (have never noticed it in movies). I have noticed that my velo is the only component in my system that uses a 3 prong power cable and like all of my other components i have it plugged into a monster hts-2500 power center. Thus here are my questions: Is the hum possibly attributed to a problem with the velo amp/can it hurt the sub? Would it be beneficial to put 2-3 prong adapters on all of my other equipment (since all of the other things are 2 prong) to isolate a ground loop(amps whcih are hk, hk-525, tv, dvd etc...)? If others with this series velo were in my shoes would you be alarmed or just consider yourself to be overreacting? Thanks for any that reply and please throw out all the suggestions that you can. -Eric Quote Link to comment Share on other sites More sharing options...
garymd Posted May 14, 2004 Share Posted May 14, 2004 Is it a buzz or hum? Big difference. I had a buzz from my preamp that went away completely after adding a 2-prong adaptor. They cost less then a buck so it's worth a try. Quote Link to comment Share on other sites More sharing options...
ekbriggs Posted May 14, 2004 Author Share Posted May 14, 2004 hard to say if its either. sounds more like a loud hum when the volume on the sub is pinned. i know that velodyne had some trouble with the FSr-18 s in the past but i do not remember the remedy that they suggested. -Eric Quote Link to comment Share on other sites More sharing options...
ekbriggs Posted May 15, 2004 Author Share Posted May 15, 2004 Just for my clarification was exactly does a 3 prong to 2 prong adapter due, i guess the question is why would removing the ground help to eliminate noise? -Eric Quote Link to comment Share on other sites More sharing options...
SteelerFan Posted May 15, 2004 Share Posted May 15, 2004 When I bought the NAD amp and pre-amp the hum I had didn't get any louder as the volume went up, it was always at the same level. Drove me nuts during the quiet passages. The adapters didn't help so it all went back. Turns out the problem was in the grounding of the amp itself.
