Just wondering how to set-up rear speaker delays, i have already set the distance but don't know how to work out the delay? is the a formula?

If you've keyed in the speaker distances then the amp will take care of the delay times automatically. :) For the record, 1ms = 1ft roughly. So for every 1ft you are away from the speaker you add 1ms.

On my amp you don't have to set two seperate functions as inputting the distances automatically sets the delays

THX Amps/Receivers should have a speaker distance input where you just key in the distance you are from each speaker and it sorts out the rest. I'm sure it's part of the THX spec.
