Anyone know about speaker 'humm'? or 'buzz' and how to get rid of it?

    First off, I'm not an audio or electrical type person so some of this may sound dumb or I may use the wrong terminology so bare with me.

    I have two KRK Roket 5 sound monitors that I use for speakers with my iPod. (see pic)… The cables use 1/4" connectors. The two channels are plugged into an adapter with a single small plug that goes into the iPod.

    Now, here's the thing. The speakers hum very slightly even when they're unplugged from the iPod (almost inaudible but I can hear them). When I plug them in, there is usually a fairly loud *BURRR* as the adapter is inserted. That goes away pretty quick. But here is the really weird part, any time I come within 3 feet of the iPod while the speakers are plugged into it, it makes an audible (not loud but obvious) BUMM. (Apparently I'm a highly *charged* kinda guy).

    So… my question is, what can be done about this? Is it the adapter? Do the speakers or cables need to be grounded in some way? Any ideas?

    TIA

    You need those $500 Monster Cables. icon_biggrin.gif

    What you describe sounds kinda normal, except for the part where it makes noise when you come closer to it.

    I would start with getting new cables. But not the crazy expensive ones they sell at Best Buy. Go to Fry's and find a set of cables/adapters with gold connectors.

    If you're willing to spend a little more money, I'd suggest getting an ipod -> RCA audio adapter cable. It will help minimize the introduction of interference.

    Make sure you are not placing them near other electrical devices ... it might actually be the ipod connection that is causing the interference

    Do a search for "KRK rokit 5 humming noise."

    Seems to be a huge problem.

    Yeah. True. I am a wuss these days. Hasn't always been the case. Used to have big speakers (not quite *that* big); huge live-work space, surround sound, a huge wall for projecting w/ my digital projector. Those were the days. Now, not so much.

    No other electrical devices.

    Thanks for the advice. I bought the Rockets at Frys years ago but they've always had a bit of a 'hum' -- not this specific proximity interference problem tho -- so I guess I should go ask for their suggestions. Mostly I listen with my Scoche buds or head phones anyway. Just sometimes I like having it on in the background.
