Noise when HDMI is connected


Hi! I just bought the ETC and it is causing noise in my audio circuit. After testing, I t when the HDMI cable is plugged in ans even when the power cable is out (with just the audio in and the HDMI plugged). Any idea??



This sound like a ground loop (especially since it happens without the ETC being turned on). Can you make sure the outlet supplying the power to the TV is on the same circuit as the audio/ETC circuit?


Yes it is. They are on a shilded powerbar.
