I have a Denon AV2803 receiver. I need to introduce a 1 frame audio delay to compensate for a tv which delays the image by 1 frame. I understand 1/25th of a second (PAL 1 frame) is about 40ms. The Denon AV2803 has a Delay Time function for the speakers, but they are in metres (or feet). I just need to be able to calculate how many metres equal 40ms delay and this should give me the delay I want - without having to buy another receiver. (Hey, I only just bought this one!) I now realise I should have bought a receiver with a master - or even component specific - delay, but it is too late now. Please help. Is there a chart that could help me work this out?
