You don't say what's at the other end of that cable. It's a player in this scenario, too.

Why does my HTS-20 powered subwoofer make a low hum when plugged in, even turned off and not connected to the receiver and a louder hum when the subwoofer power is turned on?


I suspect the amplifier is damaged. This is not an easy repair to do unless you are well versed in audio electronics. I would recommend a repair shop to look at the subwoofer amplifier.

Frender frontman212r has a huming noise when pluged into guitar.


If the humming ONLY happens when a cable is plugged into the amp, the problem is in the cable or the guitar. Poor quality cables or wrong cables will result in hum. Defective wiring or connectors in the guitar OR having the guitar near a source of magnetic fields will result in hum. We cannot diagnose these possibilities remotely.

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.

Two speakers hum noise


Very doubtful that hum issue is ground potential difference from multiple power outlets as power cord is not grounding type (it is transformer isolated). I do agree that it is good practice to connect all audio equipment to common power strip though, especially with pro sound. Check the audio cords connecting your speakers to the coumputer sound card: 1) Make sure they are connected to the correct jacks and plugged in all the way, 2) wipe the connectors off with a clean paper towel wetted with a smidge of WD-40, 3) replace cords if all else fails. I have also seen solder joints fail on the power supply capacitors (due to vibration) causing hum -- but leave this repair to an electronics technician due to dangerous voltages.

Turn down the second amplifier (which the speakers are connected to). This hum is the amplified 'noise' from the EQ and/or amplifier. Try using a much higher graded second amp (eq 500w)

Loud humming noise from new hdtv


hello, the speakers are fualty or have a shorted connection if they came with the tv contac your seller and arrange for a replacement imediately dont wait. since they are giving you feedback dont use them they may cuase other fualts in your tv, any component thats cuases hum or noise when pluged into the tv should not be used at all.

one important thing is to have a grounded plug this also may cuase fualts down the line,
if posible get a power line conditioner or ups (uniteruptable power supply)

flat panels are very over protective you dont want the tv to start blinking. since flat panels have built in protection circuts any slight short or fualt may cuase the wide screen to go into circut shutdown mode and this will cost you more if the speakers create a short in your audio circut it may damage your widescreen internal boards and cuase a system shutdown circut (red light flashing no picture)

contac your sellers site let them know your speaker are cuasing a loud hum
and that you will need the speakers replaced these are definitely fualty
if you dont have any coverage or you got the set as is then dont take any chances use other speakers.
if you are electronically inclined you can open these up and find out whats wrong with them internaly it may be a loose connection, since opening up the equipment may void your warantee contac the store first see what they say..
good luck happy holidays

Hum in speakers


Unplug the minijack from computer to hear if it still hums. If not test speakers at another computer. if it works fine on other computer the sounncard is generating hum noise. Common problem is usually the earthing cable inside the minjack that is touching L or R speakerwire due to bending of cable and breaking off insulation. If youre up to it cut off minijack if its moulde and resolder a new one on.

Gemsound power speaker pxa105


First,
Disconnect any input cables from the amp. Turn down the volume controls and disconnect the speakers. Power back on. If you still blow fuses with nothing hooked up, have the amp fixed.
If the fuse holds, shut down and connect the speakers, leaving the volume controls down. Power up and see if your fuse holds. If you have hum, an output transistor is most likely shorted. If you have no noise, SLOWLY turn up the volume controls and listen for the hum. If all is quiet, turn down the volume controls and connect your input cables and turn the volume back up. Noise? check your cables!

Speaker hum on playback with tape or dvd


Any cable? Hum is generally a bad ground. If you use cables and speakers that have no hum elsewhere, and more than one set has hum on this machine, then the unit has a grounding problem, and requires repair on an 'open up the unit' basis.
