    Hi,

    Just wondering if any of you KHT2005 owners out there have noticed a high pitched whistle being emittied from the Sub (PSW2000)?

    I have tried everything possible to eliminate it and it just won't go away. I have had it replaced and the same thing happens on the new sub. The demo sub at the shop even does it so it can't be interference or my mains.

    Any ideas?

    Jon

    Hmm, now that you've mentioned it yes I've got a high pitched npoise from the sub too. So I switched it from Manual to Auto and the sound went away when my AV was off - ie no sound was playing. In this mode I think the PSU swicthes off and the squeal goes away. I reckon the power supply must be a switcher type which do squeal a little.
