Wouldn't the XLR 10 db attenuator pad attached to each of my XLR cables work?
Yes, it would.
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????

You know what is weird? About 1 1/2 years ago I reached out to Simaudio (I bought my Titan amp used 2 years ago and realizing this piece although in amazing condition and was sounding just amazing, it was approaching 20 years) to see what if anything I should do to care for this unit. They recommended sending it to them for "cleaning and calibrating". So I did. Knowing I was going to be without the unit for a few months I bought a Monolith 5 channel amp as a backup (the price was right at $1599 at the time) to get me through. Once I introduced this unit with my Marantz AV8802A, there was a faint hum/buzz - come to have been thinking about it it was very similar to what I have now - but chalked it up to this being a lower end and knowing it wasn't there with the Sim, I wasn't too concerned. Once I got the Sim back and connected it, buzz/hiss gone. I just remembered this today! And from what I recall it was very faint and didn't change volume wise like this current possession of my rig!
Just maybe the lifters or the attenuators will be the proper exorcism to get rid of this particular evil entity😂🤞 |
IMO, both @dpop and @russ69 give you great recommendations, if the XLR ground lift adaptoer works, it will eliminate the hum/buzz noise. Otherwise, an 10dB in-line XLR attenuator will reduce the noise 10dB (since the noise is not affected by the volume control). https://en.wikipedia.org/wiki/Ground_lift https://www.parts-express.com/Inline-XLR-Attenuator-Pad-10dB-240-412
