SOURCE: Loud humming coming from subwoofer

This can be caused due to an increase in local interference. The hum is decreased when you plug in the satellites because the interference is spread over a longer area. You may notice that speakers tend to hum around things like cell phones and power outlets. To see if this is the case, move the speakers to another part of the room if you can, slide the desk around, plug the computer in at another room, something like this. If the hum gets louder or quieter, it is interference at your new place. This can be solved by finding a new area to set up your computer stuff at. Since it's mostly the subwoofer, try elevating it off the ground, there may be a power main running under the floor.

SOURCE: Getting humming sound from all speakers. BA 700569 MicroMedia

It sounds more like the power supply is at fault (a filter capacitor dried up), but it'll take an oscilloscope to verify that - take it to a TV repair shop (if you can find one) or find a ham radio operator who still has test equipment. (If it happens even from an iPod, it'll be easy to troubleshoot, since the person doing it can use any audio source to cause the problem.)

SOURCE: My speaker set up boston acoustics ba7500 will'nt

The Guys at Boston Acoustics helped me get my speakers to work. The Boston BA7500 speakers are coaxial digital speakers so you need a digital output on your sound card. Analog will NOT work. My new HP Pavilion has a Realtek sound card with a digitial RCA plug output. I had to go to Amazon and get a male RCA to 1/8" Stereo Mini Female adapter plug. I just pluged it in and configured my sound card to 16 bit 48 khz output to the RCA output and everything works great. The speakers sound better then ever, great for 10 year old speakers! They sound better then anything I have seen avalable today. The guys at Boston were the only guys that helped with getting this to work! Thanks again to them and Amazon has every type of adapter plug you may need. Good luck.

SOURCE: how do i connect my boston acoustics pv800

You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"

Fisher&paykel ,smart drive excellence 7 .5 ,the washing machine stopped working during the pumping out of the water.no power on the top panel and a slight humming noise


What is it? No power to panel or slight humming sound which indicated there is power? Can't be both. I would suggest that the humming sound if you put it on spin, will be the drain pump trying to go. If pump is left humming like that it will get hot & shut the power off until it cools down again. Pump hums when it has a blockage & can'y spin. Clear the blockage.

Bose radio bad hum


one of the most common sources of hum is a failing power supply.
I don't know your radio specifics..... however, some things to consider/try : if it can be battery powered, try it with batteries.
If hum disappears, then source is power supply. Power supply
hums are usually 60 or 120 Hertz (cycles per second). The most
common failure component in power supply, causing a hum, are
the filter capacitors. If you do try to replace these, be very careful
and discharge the old caps before you remove them - to avoid a
(potentially dangerous) shock... caps can retain a charge for many
days, sometimes. Another source of hum is if the radio is close to
a flourescent light, or other appliance which may radiate power. If so,
try moving radio. If the hum is high pitched, then more info is needed.
Hope this helps!

The subwoofer output on my Kenwood VR-606 has suddenly stopped working. I have tried the "setup" several times, turning the subwoofer off and back on. Also, when I first power up the system, it emits a low...


It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
Cheers, Don.

Hum in my eons


The hum is because your connecting your speakers to the same power strip or extension cord, try connecting each one from different power source. I had the same problem with mine.

I have a pair of JM lab Electra 905 speakers, running through a DNM amp and power amps. When powered up, the left speaker makes a very loud humming noise. This has happened recently. I haven't changed...


Hello
Switch on your amp, keep its volue down to extreme low, and listen if there is still hum through the left channel or not. If still there is hum, the left side power amplifier section inside the amp;ifier is faulty. If htere is no hum at this state, hum enters thorugh the audio input terminal, and the input wires must be checked for open sheild connection. OK.

Major hummimng noise when sub is connected to receiver.


Is the hum in the receiver-attached speakers or the sub?


Self-powered sub?


How is the sub attached - RCA or speaker-level?


Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.


If it hums with the sub attached, unplug the sub's power cord. Differences in AC ground potentials will generate hum across linked devices.

NAD S300 Amplifer humming


You have either got a bad earth connection, or possibily there's a capacitor failed.
If you can't find a dodgy conection, I would replace the large Electrolytic Capacitors in the power section, they are used to take out 50hz hum in the mains electric, when they go you get that hum coming into your system.
