Speaker delay settings... help?

IceBus · 27 Jan 2006 at 17:37

This may be because I'm tired from setting this up all day, but I'm really struggling to get the correct delay settings for the centre and the front L&R speakers of my new Denon 500SD

Any tips on the best way to do it? I've measured the position from the speakers to my seated position and tried inputting those values but it doesn't work. I just don't seem able to get it to lip-synch.

I'm going from the Denon 500SD straight into my TV via RGB scart (at least until the new HDTV shows up...).

Thanks,

Pete

Speaker delay isn't going to adjust for lipsync, you may have another issue or there maybe a global delay setting somewhere.

I thought that was what speaker delay was for? i.e. for every speaker (centre, fr, fl, rl, rr, sub etc) I can adjust it for how far away I'm sitting.

It does this with all media through the amp, not just DVDs - i.e. TV as well.

Any ideas?

My denon 1906 has a single lipsynch delay setting, and this is seperate from any speaker setup settings, hell you'd have to have a really REALLY big room before you'd have to start worrying about delay between the individual speakers lol, at least 100 metres or so

I just used the auto speaker setup by positioning the directional microphone on the back of my sofa and letting the amp do it's auto config with it. I didn't need to adjust for lipsynch anyways as I didn't have the issue with my amp or tv. I hear that's mainly for those dodgy plasma screens.

I seem to have sorted it, by setting the speaker distance slightly too far away and lowering the actual speakers slightly (I'd forgotten to lower them to ear height post-installation) and it seems to be fairly close now. I'll probably have to do it again when the new LCD turns up so it's not worth getting it perfect in the meanwhile.

Thanks for the help guys.

Not quitetrue, depending on frequency you can get phase errors on very very small time differences which is why many people can get close but not exact

It is a problem when using pairs of cardiod mics to record things

As the brain uses phase to place things it cannot detect through other senses, it makes sense to get it as accurate as you can!

The lipsync delay setting is to allow the DD/DTS decoding to be done (which takes longer than it does to get the picture to the screen). This will be applied exactly evenly across all the channels - the rest of it is to counter distance issues and stuff.

The auto-setup is there for a reason! Use it if you have it people!
