  1. LittleLite-Induced Hum

    CD Players | Turntables
    It's really disappointing not to be able to use my task light for its intended purpose. Mounted on the side of my turntable's dust cover, my wall-wart powered LittleLite induces a low-level hum into the cartridge circuit even when the lamp is turned off! Stranger still: the hum only starts...

  3. Hum

    Pro Audio
    A friend of mine found this good article about XLR to RCA, or to 1/4 phono, and hums. It is a very good read IMO, and my friend is making me a new cable to the specs in the article to see if it eliminates the hum from going from the balanced XLRs to the RCAs on our Parasound amps. We have tried...

  6. Subwoofer hum

    System Setup and Connection
    Hi, I did some research on this, and I can't seem to find a good answer under these circumstances. I just bought a brand new Pinnacle Subsonic subwoofer, and I'm noticing a hum/buzz from the unit. Even if I unplug all rca connections and keep the volume down it is still present. It seems to be...
  7. Dayton UMM-6, ground loop hum?

    REW Forum
    Hi I've just got the Dayton Audio UMM-6 microphone and got the REW installed on the laptop. My issue is that when I connect the laptop to the Receiver (Denon X4000) through Aux, there is an audible hum. Increase in volume makes it louder. Ive tried connecting my phone through the same cable...
  8. Panasonic plasma hum from external speakers, not the tv

    Panasonic / Technics
    I am stumped about a hum when watching a light-colored image on my 65VT60. I've read about humming plasmas, ground loops, bad transformers, and so forth, but this hum is coming from my front speakers. I am unsure where to start diagnosis, because the hum does not come from the transformer area...

    I've got an emotiva umc200/upa500 combination.

Recently though I have noticed a pretty obvious hum coming from all 5 speakers. I first...

  13. RCA Victor Custom Series 711 Hum

    Two Channel Audio
    Hi, I just bought a RCA Victor Custom Series 711 which is in mint physical condition. Really nice credenza radio/turntable. It has an intense ground hum and the left speaker is very quiet. The headphone out behaves the same way so I believe it to be the amp. I've looked inside and it...

    Home Theater Receivers | Processors | Amps
    I have an Adcom GFA-7500 power amp, and noticed yesterday there is a mild, buzzing sound coming from the unit (not through the speakers). Any thoughts on what it could be?? I unplugged the power cord from power strip, and plugged directly into the wall. There was no buzz at first, but then...

    So at baseline my monitors have this "usb" sound. That's the only way I can describe it... it's about 1khz and modulates like a cd drive reading something. Any idea what this is or what one can do to minimize it???

    Hey guys, I've just purchased my first sub (well not exactly first, but I haven't had one in more than 10 years), and I'm in the process of integrating it into my 2 channel system (which also serves as HT system). I'm hoping that you can help me get things properly set up. My system...
