The newer devices (about 6 months or younger) do have another power supply than the older ones. This is a switching power supply and this power supply causes a 16 kHz beep at the Audio Output (if you have a good ear, you can hear it). Also there is a peak at 26 kHz but you cant hear that. I suppose that some harmonic waves at higher frequencies could cause interferences with equipment placed near the Audiotron. Regards Konrad
