    60~ Hum In Logitech Speakers


    I got some new speaker from Dell today, the Logitech Z323 than has a subwoofer and two speakers. Set up was quick and the sound was superb.

    Here's the problem...very noticeable 60 cycle hum from all speakers. Not so much when music is playing, only during the silent times or if it's off with no music you can hear it. Any ideas? I tried emailing Logitech but theyr'e undeoig a transfomation with their system and no email till the 29th according to the website.

    I went by the instructions and put the green male cable from the right speaker in the green port in back of the computer as shown in the directions.

    How are the speakers powered? Does the socket that the speaker's power adapter plugged into have a good ground?

    Yes, and in fact the noise has went away? I unplugged and re-inserted the plug from the main speaker to the computer and now it's much better.

    I can't seem to have much luck with these speakers. Last night when I shut down I turned off the right(main) speaker by the volume control knob on the front. This morning at boot up I turned it back on and no light on that speaker to indicate power and no sound. I let the mouse arrow hover over the speaker icon in the system tray and it showed "Speakers 18%". Maybe that's the balance that's configured. There's still no sound.

    This almost sounds to me like there could be a small short of some sort in the power supply for the speakers. Have you tried to see if you get get a hold of and try out a different power supply? if not i would give this a shot as thats what it sounds like to me.

    All I did was turn it off last night and back on his morning. I disconnected the connection between the main speaker and the computer and re-inserted....nothing. It sounded so good last night. I don't have another power supply.

    Here's what I just tried. I took the lead that went into the sound card and plugged it into a portable cassette player/recorder, turned on the right main speaker and got sound. However, the power light on that speaker still didn't come on. I unplugged everything and started over and still no sound and no power light.

    OK-I tried the most obvious problem an checked the outlet for power...none. I went outside and checked the breaker and none had tripped although I just reset that breaker anyway. It did no good. I decided to just plug into another outlet that was powered, turned the speaker on and no power. I had just checked that outlet and it had 121v on it. When I unplugged the speaker cable from it and rechecked it now has no reading. I don't know what's going on.

    Well you should take a portable device and the speakers and set them up in a different room, if all's well then the issue is that outlet and that could be all sorts of problems. Could be time to replace the entire outlet and if possible go with a medical grade outlet.

    There must be a short in the main speaker or the sub woofer as it keeps knocking out the outlets. I tried it in two of them and after doing so there was no power to those outlets.
