Low buzzing through speaks
Hello All,
Need some serious help here. So I just (upgraded?) from a Marantz AV8802A to a McIntosh MX122 preamp. I also just got brand new Revel Performa3 speaks all around (5 channel setup). I disconnect everything from the Marantz and then into the McIntosh, connect the speaks and I have a faint buzzing through all 5 speakers (that was not there previously). I have everything plugged into a Furman Elite 20pfi power conditioner which is plugged into a dedicated 20 amp circuit. My power amp is a Simaudio Titan HT200 5 channel. This is not going through the Furman but directly into the other outlet on the same 20 amp line. I even tried plugging the Sim amp into the Furman to see if that helped-no change faint buzz is still there. I have unplugged just about everything, and the buzz is still there. It is very faint and does not get louder when I turn up the volume. Again it is faint and you have to put your ear up to the speaks to hear but it is definitely there. I have tried so many things and nothing gets rid of it. It is not my cable box (I did have that issue previously with the Marantz but as soon as I unplugged the coax from the box it went away so I just bought a coax loop eliminator connected the cable to that and noise was all gone) as I unplugged that and started there.
Any help would be so sincerely appreciated????
Thanks so much again @dpop! Unfortunately I do not have any other XLR cables. I do have some old speaker wire I can hook up though. Does it matter if I use the positive or negative to connect the 2 units with the ground?
You wouldn't by any chance live near the NH area would you? Be happy to pay for your services to come out, LOL! |
I do not. Sorry. That would make things a little easier wouldn't it. 😄 OK, so no spare XLR cables. Noted. Regarding the speaker wire that you have, we really only need to use one side (like either a plus or minus). Can you easily attach that to those ground terminals? Even if you just hold the wires against the ground terminals for a moment, while hearing the buzz, does it change the sound of the buzz at all? |
Definitely not easily, but I think I can do it. Unfortunately, damn work is now going to get in the way😡. I won't be able to get to this until tomorrow AM...But first thing I'll connect the ground wire...
Until tomorrow once again @dpop thank you, thank you, thank you. Sincerely man. Your time and support are greatly greatly appreciated. I will do the wire first thing tomorrow and report right back as soon as the experiment is completed...Have an awesome night and thank you again! |
Not a problem. We’ll take it from there. One other thing, I think you mentioned that your XLR cables were intertwined with other cables? Was that correct? Were any of those ethernet cables? Also, if they’re still intertwined, would it be possible to physically separate at least one of the XLR cables from all other cables, and connect it (all by itself), and see if any buzzing exists? |
I did separate the XLR cables from any power cables and used a zip tie to keep them from separating and touching any power cables…I checked out that XLR ground lift cable via the link you sent. How does that work do you just plug the XLR cable into that and then plug the whole thing into the Mac? Like if it worked would I need 5 of those on each XLR cable I have? |
