  1. BFD output hum -not ground loop associated

    Electronic Processing/Equalization Devices
    I added a BFD 1124P to my system in October. After following the forum threads I decided to play with my settings. I verified and eliminated my ground loop hum with a cheater plug. Temporary fix, I know. Ran REW, found my peaks and assigned filters. I input my filter values into the BFD...
  2. Buzz Hum Problem

    System Setup and Connection
    Hi, I was wondering if you could give me some input to a slight problem I have been having? The other day I still noticed the very slightest kinda hum buzz going on in both of my channels. It can only be heard at all if the amp gains are past half way up. If you were not listening for it most...

  4. Eliminated the dreaded BFD hum for free

    Electronic Processing/Equalization Devices
    For years I've been able to get rid of ground loop hums in my system by simply attaching a piece of speaker wire to the chasis of one piece of gear to another. In the case of the BFD there's a siliver grounding screw underneath the unit right in the middle. All I did was attach a piece of...
  5. Hum from speakers??

    AV Home Theater
    My system consists of a Denon 3803 receiver, Rotel RB-1070 2ch amp for the mains, Rotel RMB1075 amp for the centre and surrounds, driving B&W 600 series speakers. Last night I noticed a hum/buzz coming from my centre and surrounds when I got close to them. The hum does not increase when the...
  6. Noise or HUM from BFD

    Electronic Processing/Equalization Devices
    I am getting a humm or noise from the subwoofer with no inputs. This noise occurs with or without a subwoofer input to the BFD. The noise does not occur when I switch to another preset with factory defaults. I have 7 filters in the 20 to 100 Hz band. Seems like it occurs with even 1 filter...
  7. What solution do folks use for the dreaded BFD hum?

    Electronic Processing/Equalization Devices
    I'm a big believer in standing on the shoulders of giants. :) In this case that means I would like to know what solution folks use for addressing The Hum. Right now I'm using a cheater plug, but I would like to solve the problem the right way. I saw the links to Jensen and Ebtech stuff, but...
  8. Ground loop hum?

    Electronic Processing/Equalization Devices
    Bad lightning storm a few weeks ago, and ever since I have a loud humming noise coming through my sub when the BFD is connected. (not conneced no hum.) Sounds close to 60hz (My wife still wants to know how I know that (she calls me a geek)) Anyway - went to rat shack and bought this Ground Loop...
  9. The hum of frustration

    Electronic Processing/Equalization Devices
    This really shouldn’t be that difficult. I make no claims to being an A/V guru but computers and software are not a problem, I deal with them everyday. But I simply can not seem to get this going. The BFD is not a problem. I can run test tones and make filters manually no problem. Getting...
  10. Please help with hum in IB with BFD

    Electronic Processing/Equalization Devices
    I've got an IB sub with BFD and EP2500. I've got a nasty hum/buzz coming through my sub drivers that I have traced to the interconnect coming from the sub out on my Rotel processor. Of course the I/C goes to the BFD. When I remove the I/C from the processor, the hum goes away. I've tried...
