Which delay for Dolby Digital on RSP-1066?

[pbarata]

I’ve recently moved my surround speakers and now I have a higher distance from listening position then before.

After making some measures and calculations I end up with a suggested delay of 3 ms for Dolby Digital.

Unfortunately RSP-1066 only accepts increments of 5 ms, and now I’m a bit confused on which one to choose. If a 0 ms delay or the next possible step, 5 ms delay?

Is there any practical rule for proper rounding in such situations?

Most likely I’ll move again the surround speakers to get exactly 5 ms. :W

The best recommendation I can make is, move the speakers so there is no need for a delay. Compensating distance by delay is bad: it does not consider sound reflection in the room, and gives a satisfactory result in a very limited area.

"Most likely I’ll move again the surround speakers to get exactly 5 ms."
Why not move again to get exactly 0 distance to offset? Just move the L/R speakers a little closer to you?

Thank you very much for your valuable reading. For my surprise the speaker positioning is quite different from the one recommend by Dolby Laboratories in their literacy. Normally they located the surround speaker’s lateral to the listener.

Yes, this document contains a lot of info, and sometimes against other recommendations... But I consider this the most up-to-date comprehensive document. It was presented to me by Michael Bishop, recording engineer at Telarc, and he claims it matches what industry professionals are doing today.
