last try :) buzz in system

the buzz can be heard when the music gets soft at a listing level about 90- db or better. it only resonates when I am listening to a CD. If I have a movie going through the Denon, I can blow the walls off and on quiet parts, no buzz. It has to be comming from the dap. Also the interconnects ai use are apature silver. they have a mylar sheild in the jacket,and they are grounded. Is this god enough, or do I ned to go to RF blockers, or what.

If your system is on but not playing music, do you hear a buzz? If you replace the proceed with another CD player, is there no buzz? CD players give off a type of RF that may be affecting the connection with the JVC. Have you tried using a different input in the JVC? Hum, as you are now experiencing, is one of the most difficult problems to cure.

Sounds like one of two things. First, if you have cable TV hooked up to anything in your system disconnect it and see if hum goes away. It may be a cable caused ground loop easily solved by a ground breaker obtained from your local dealer. It more likely sounds like a ground loop happening in one or more components. Try the 3 to 2 prong AC adapter on one component at a time until the problem goes away, or you could use an extension cord to another outlet on one or more components to see if the problem can be minimized or go away. A separate circuit from the main system is preferable for this method. Some AC power boxes (Panamax, etc.)are sometimes good at breaking ground loops and eliminating this problem. One more thing it could be is RF (radio)beaming into the DAP or other components. Are you near a TV or radio tower? If so, you may have to change the afflicted component to solve this one, although sometimes a different position in the room or turning the unit affected sideways helps. I live in Seattle, and there's a lot of RF problems here! Let me know if any of this helps! --Tom

I have tried the turning of the unit and placement away from the television, still a problem (with different cables.) I will try the 3-2 prong method and see if that helps, also, no cable tv, just DSS. The buzz also presents itself when another transport is used. I can run direct to the amp if I want from the DAP.even If I disconnect everything from the DAP and just run it into the amp by itself the buzz is there. UGH
