Tv and speakers buzzing noise


If the hum is a low note continuous hum, its at 'mains' frequency. The power cables to the unit (or inside it) are getting too close to the cables that carry sound signals to the center speaker. The mains power naturally hums and if mains wires are near to audio kit wires they pick up this sound and play it through their system/speakers. Check the wires to and from it make sure the connections are good and firm. Seperate these wires by at least one inch from any power cables, use tape to hold them down and away from each other.

I have the JBL speakers which are really decent but i want them to be as loud as possible! if i plugged in my logitech speakers into one of the inputs that i would normally put one of my little speakers in...


It should be OK BUT if the JBL and the Logitech are plugged into different mains outlets you could get a hum from one or both sets of speakers. This hum is caused by an earth loop when the speakers are connect to different mains outlets.
The fix.
Connect a power board to a mains outlet and then plug the mains connections from both set of speakers and computer to this power board.

Speaker humms only. what causes that?


Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

I get a humming sound when the ipod is attached,


the hum comes from three possible sources, the power unit can cause it before failure, the amplifier which can effect one or more speakers or the interface board between the other two, the interface board and the power board are known problems to b and w, so if you have not already contacted service at b and w, then do so.

Bad Humm out


First disconnect all inputs. If hum is still there, PROBABLY the filter capacitors have gone bad. Replacement is the cure.

IF there is no hum without any inpout cable connected, there is a ground loop and either the ground at the inout connector is broken, or your cables and guitar may have a problem.

Humm


where is the ground wire from the turntable connected to ? Ensure that is is connected to the phono pre-amp's ground.

Is the turntable sitting on top/near any other equipment ? Try changing the position and see if the hum reduces. If yes, then it is likely that it is picking up hum from a mains transformer.

Acoustimass Subwoofer has a low "hummm" sound when turned on.


Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.

Gigabyte 8S648FX-RZ Motherboard has problems running multiple IDE devices


Ok, you have 2 x UDMA ATA 133/100/66 Bus Master IDE ports on that motherboard, so you can support 4 ide devices. It is important that you split your devices between the 2 available ide channels (each channel has a seperate ribbon cable). For example if you have 1 hard drive and 1 cd drive you'd want to place each on a seperate channel. If you have 2 hard drives and 1 cd drive it's best to place each hard drive on a seperate channel and the cd drive on the same channel as one of the hard drives. You have to make sure the jumper settings on the drives are correct (1 master and 1 slave) when placing 2 drives on the same channel for example. Most likely your jumper settings are not correct and are causing this problem. The jumpers are located on the rear of the drive near where the power cable is plugged into the drive. Most hard drives have the jumper setting printed on the hard drive. Once the jumpers are correct you should be ok.
