The sound you are discribing is indicative of a short in the audio cable coming from your amp to the woofer. it doesn't mean that you have to replace a cable, but it could mean that one is loose. I would first try to turn on the unit and then start unpluging each speaker from the back one at a time. If the sound stops then you know that the hum is caused by the last speaker cable you pulled out. It is possible that you could make a temporary fix by twisting the cable back and forth where it connects into the back of each speaker. (Though this would only be a temp fix.) Because these cables are hard soldierd into the the actual speaker, there is no way for a person to simply replace the problem cable.

The other possible problem could be with the cables coming from the computer. You might simply have the cables in the wrong inputs. They should be color coordinated. Yellow in yellow, etc. Or with the system on, unplug these cables one at a time to find the problem cable.

If non of these work, I would bring it back to the store for a replacement system if still under warranty.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

My home theater speakers make a constant hum whenever my receiver is on. The loudness of the hum changes with the volume control, and goes away entirely when the system is muted. All components are plugged...


jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

Logitech Z-5300 subwoofer from computer to i-pod problem...


The best thing to do is to contact the manufacturers. From this i understood that your speaker system is new. You surely have the manufacturer's guarantee. So its better to contact them than to get it repaired or replaced for free. Sir please do not try to open the sub as it will void the guarantee policy.

Hope your subs come into play as soon as possible.......
All the best...

Loud hHum from Subwoofer


Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.
