I use an Onkyo 606 with KEF 3005SE and KEF Wireless system. When in standby I get a low hum which isn't there at all when teh system is being used. The dealer is telling me that there is a fundamental incompatibility between the Onkyo and the KEF Wireless system and I need to change the Onkyo. Is this right and is there nothing I can do to get this working ciorrectly? Hi mate, any luck with your problem? I've got the same problem. I have just put together my new system consisting of: Sony AV receiver (2400es) Kef 1005.2 speakers Kef wireless system QED speaker wire and QED HDMI cables I get a static (slightly crackly) noise coming from the surround speakers when the transmitter is powered up and everything else is in stand-by. As soon as I switch on the amp it goes silent! What TV have you got because it seems to be my TV causing this somehow. If I detach the HDMI cable from the back of the TV the noise stops. If I switch off the TV at the mains the noise remains. But if I physically unplug the TV from the wall the sound will then go. I have a Samsung 40" 6 series LCD and it seems to be sending some sort of interference down the HDMI cable but I'm totally baffled how (because the noise remains when the TV is powered down). I am just about to start contacting the companies for support. It's a right arse. I do have a further problem actually. When I am watching something in 5.1 all the speaker do perform very well. But it seems like when background noise (on the film or whatever) is fairly quiet, the kef wireless system seems to click in and out and if I put my ear to the rear speakers I can hear it crackling in and out. It does not do this if the signal is louder (e.g. during a speaker noise test from my AMP). Look forward to hearing from you, Cheers, Mark
This is cycle hum place offending units away from each other or, isolate the power supplies and, re- check electrical circuit grounds
To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" button while doing that press the "STANDBY/ON" button. You will see the word "Clear" in the display screen and the receiver will go into standby mode. PLEASE UNDERSTAND THAT YOU WILL LOSE ALL YOUR AUDIO & VIDEO ASSIGNMENTS ON THE RECEIVER PLUS YOU WILL LOSE ALL YOUR SPEAKER CONFIGURATIONS, SPEAKER DISTANCE AND ALL LEVEL CALIBRATION SETTINGS. YOU WILL ALSO LOSE ANY PROGRAMMED RADIO STATIONS IN MEMORY. Once the receiver goes into standby mode turn it back on and go thru the setup menu for all custom settings.

Thanks for the response,
I actually was trying to respond to the person with the Onkyo amp who seems to have the same problem.
So this cycle hum; is it from the TV? And does this occur when it is switched off at the mains?
I have tried plugging the transmitter and TV in different sockets and using different strip plugs but it does not make a difference. Why when the amp is switched on would it cause the static noise to stop?
Thanks for the help,
Mark
