As stated. im currently using Altec Lansing VS4121, and everytime i turned on my speaker there is this buzzing sound from my sub-woofer(not sure).

wonder if anyone having this problem as well??

mine 4121 serve me well...can u describe more bout the sound? does the sound stop after a while of continuously?

dude
check ur connection.

The sound was continuous.
Actually if din pay much attention on it, its quite hard to notice the buzzing sound.

yeap, check those plugs, all of it r probably pluged in.

hmm....
izzit possible tat it is sumtink to do with the electric current thingy??

actually im facing the same prob too wif altec lansing speaker, forgot wat model, stop production d.

the buzzing sound appear only at certain volume level. very annoying....

are you using wireless connection, and the modem is right beside your speaker?

if the buzzing sound rhythm with ur pc load or whenever u move ur mouse, try changing a better psu.

if u have a TV card. try plug put the line-in cable.

I think my Altec Lancing facing almost kind problem like this, the Sub woofer might give buzz sound if i play loud Bass music, like something loose inside the woofer

Mine has a low humming sound too when i connect it to my DVD player and PS2 unit, and the humming is continuous. The sound will not exist if I connect it to my laptop. I've checked with the user manual and it says in there that this humming is normal. I've placed my subwoofer unit an approximate 2 and a half feet away from my TV, DVD and PS2 unit and also away from any AC power source sockets. However, the humming sound still exists. Gotta learn to live with for now as the user manual states it to be a normal behaviour. Comments??

Try send back to warranty...
Last time it happen to me, so i sent to warranty department n fixed
Not every products made by 100% perfectly

i have the same problem with my AL VS2121.. the only way to stop the problem temporarily is to plug the power socket out from the power source and plug it back...

@vahn87

mine got the buzzing sound when i move my mouse.. why like that wan ar?
why need to change the PSU??

The VS4121 has a very interesting design, but a noisy power supply and a disturbing buzzing sound.

erm, not 100% its the psu prob, cos many thing will cause this...

cos our house power voltage = 230 but it doest mean the it will constanly stay 230 somtimes will vary...so it will somekinda wear off ur psu slowly....(can be solved by getting a new psu, or getting a good psu which will filter noise)

or the electricity cable in ur house(in wall) was done by noob electrician (can be solve by using a lonnngg + thick!!! extension wire ) lonnngg n thick!!*
u can try bring ur pc n the speaker 2 ur fren house n try them if it is house electricity prob.

or maybe its static prob in ur rig, like mobo having contact with case metal n etc (can be solved by using 'non conductive stuff' between every screw that locks ur mobo with case)

above prob are not 100% thou, but it happened to lotsa customer when i work as part time technician...was scratching my head when i cant troubleshoot them last time after selling those stuff 2 customer

The humming sound is actually caused by our dirty power line aka A/C line noise. It's normal to hear humming sound from transformers of your Hi-Fi stuff. That's why you need a power conditioner, something like the one below or any other brands you can find in the market.



PS Audio UPC-200HB

Why don't you tell them the cost too?...the one you highly recommend.

Nevertheless, I think if a VS4121 is humming, there's surely something defective inside. Mine is DEAD SILENT! (regardless whether its plugged to a AVR or some wall socket at home and it doesn't have an extra earth wire either)..not rosak of course!

Hey guys, thx for dropping by.


sunauto, i would like noe more bout this product, u mind giving the price tag as well as where can i can it. it sure sound nice to me to have 1 of these.

I thought an AVR should be able to solve this problem as it will ensure stable voltage supplied to our PC.

I'm not sure about the latest price but it aint't cheap b'coz it's an audiophile product, it could even enhance the picture quality from your LCD if connected to it. I didn't buy it as I have other plans in mind, planning to buy Wireworld power cord and Tundra (power strip), another alternative method to surpress A/C line noise effectively.

Going back to the main issue, I still think there's something wrong with the TS's speaker set and no additional gadget will cure the problem.
