    Hi,
    No hum when the krell is unplugged. Only when it is switch on and connected to the speakers. The hum comes from the speakers.
    Thanks

Hey tong

This confirms you have an earth loop problem then. Has it just started, or has it been this way from when you first set up the gear?

Power supply noise lg 42LV3730?


If your tv uses rca a jacks to connect it up to the reciever, You coul try what is called a ground loop iceilator, It hooks up to the patch cord,If they are still availible.They were use on car Stereo,s when you have a amp hook up to it,In some vehicles you would get a ground loop hum. Radio Shack might still sell them. You could try one.It work for me with a (Carver) Power amp that i use to own.

first of all you must connect as follows.
1-preamp/mixer-------equalizer/reverb unit------amp-----speakers(keep all equalizer control to 0db).
2-check your cables for good connector no touching of any inner wire to chassis of any equipment.
3-go to radio shack and buy(ground-loop isolator).
parts code(270-054)-----better to buy two pieces and connect it between your equipment.

Lots of hum from both speakers


Well folks I solved my problem and the amp has never sounded better. It had always hummed and now it close to stone quiet. The secret was it really never a problem with the amp. The problem was the result of either the pre-amp, interconnect cables, or the combinations of them. The solution came when I added a "drain wire" or ground to the cable I was using. There must have been a ground loop or some in-balance that required a wire to be connected to the earth (-) side at the source on the interconnect and then left unconnected at the other or receiving end of the interconnect. Anyway, no more hum, and the solution took some spare wire and solder.

Humming noise.....


Try to isolate the grounds of the amp and that of your head unit. I mean 'lift' the ground connection. Just connect the hot side and not the ground wire - your amp's grounding and your head unit's grounding might have a voltage loop. smile when the hum dissappears.

P4500 yamaha amp


first check your input cable-disconnect it and check if the problem finished---you will have a problem in input(cable or device)-start with another cable then your input device.
if the problem still check your out put cables(speakers cables)for short circuit or touch the bare wire with amplifier body.-try to clean volume controls with spray contact cleaner---confirm good connection in amplifier rear and in speakers rear.

Annoying hum


First of all touch the metallic body of the amp with your palm after removing your footwear and find out if there is a reduction of the hum sound. If the hum is reduced that means there is no proper earthing .Check whether the power supply is properly earthed.If there is no earth connection in your home wiring there will be hum.You can ask your electrician to solve this problem and then switch on the system.
If the problem persisits check the audio cable for any damage and replace the cable with a new one.
Sometimes the hum may be caused by a tubelight which is taking power from the same plugpoint you are using for your player.this can also cause noise.

A23 AMP


If the amp hums with just speakers connected and no inputs. The problem is internal and Parasound should take care of it under their usually prompt warr. service which is still in force. 5 months sound odd. Was your dealer getting it or was it direct? If not them connect one component at a time, add preamp next(nothing connected to it). If it hums them use a 3-2 ground lifter on the AC cord of the amp and do not connect the wire to the outlet screw. If not them connect each component. If you have cable very often this will cause hum even if you are not listening to cable sound. Use a ground isolator in line with the cable RF input.
