    I have humming through my sub woofer problem too.It got so bad that I can no longer have it hooked up to the stereo.So its out of commission.

  • fabyouless Apr 09, 2009

    When i go into the SET UP menu on the STR DE698 and set S.W. to NO, the humming stops. It's got to be a problem with the circuitry in the receiver.

My Velodyne DPS-10 subwoofer hums when you plug in the RCA cable. The hum increases in volume when you touch the rear metal panel.


hi,
You have to check the RCA cable to the sub woofer. The RCA cabe have two connections inside it, one is for gain and the other is for ground sheild. If the ground sheild is broken then there will be hum from the sub woofer and it will increase if you touch the ground (rear metal pannel is connected to the ground). Replace the cable and check it again.
ok

Powered subwoofer has hum


First of all confirm if the hum is an internal or external problem.
Disconnect the RCA sub woofer input from the back of the unit and turn it on. If there is no hum it could be the interconnecting cable or the output from the receiver. But in the stand alone mode if the sub woofer hums when powered on you have internal problem and will have to be looked into by a professional.
Many a time the earth or the shield of the interconnecting cable is the culprit, because the sub sits on the floor and you might shift it for cleaning the floor and the cable can stretch and snap internally.

No sound comingout now on my HT BD2T subwoofer,just humming.


Try reconnecting; then replacing the audio cable for the sub woofer. I think it is just a standard RCA cable.

When you disconnect the RCA cable does the sub woofer still hum? If so the sub woofer may be bad. If it falls silent chances are it's just the cable.

I have no output from subwoofer


Hello Fixya customer,

Thank you for your question.

Please check that the sub woofer and RCA cable are working by removing the RCA wire from the Sub woofer output of the Onkyou and touching the center terminal of the RCA plug. You should here a hum when it is touched.

If you get the hum, then the next step is to "Clear" the Onkyo by holding down the "VCR and Stby" button until you see "Clear" on the display. Warning, this will clear any settings special that you have made to the receiver, but will get you back to the Factory settings.

Lastly, check various sound fields, and the Sub woofer volume setting, if you still do not get sound, please have a Onlyo service center verify the output.

Thank you using Fixya.

Sub woofer has a hum


I have found that with other appliances running, or a busy circuit, I have the same problem. Try to turn everything else in the house off and check again....A/C are often culprits. You can buy a line isolator for the plug, although they are just more money to spend. If this doesn't work, well, it could be a crappy home theaater receiver. It happens

Sub


Most amplified sub woofers need to be grounded to the output source.If you plug the sub woofer in to the receiver you would use a ground wire from the receiver to the sub woofer there should be a ground terminal on the sub woofer and receiver.
