I currently have 3 sources connected to the amp: VCR1 - Tivo(Analog) VCR2/DVR - Digibox(Digital) DVD - DVD player(Digital) I have noticed that if i have everything switched off bar Tivo, i can still here sound from Tivo on all 8 of the available input selections. Is this standard behaviour? I would expect to only here Tivo if have the VCR1 input selected. I think it has been like this ever since i have had it. It is only bothering me now as rather than switching the amp off i want to just switch to one of the non used inputs (and expect to hear silence!). Thanks for any help.
