    sorry - i posted this earlier under a probably too explicit subject heading, hope you dont mind me reposting:

    Sorry if this is dumb, but my Yamaha Receiver allows me to set both positive and negative delay values for my center and surround channels...

    So if I select a +10ms is that 10 ms of delay, or does that mean the signal is actually advanced?

    Likewise if I se -10ms, is that delay or (sorry about this) negative delay, meaning advance over the fronts output?

    I am almost too ashamed to ask, but this seems confusing to my small brain!

    The manual does not refer to this directly, merely suggesting amounts of delay to use.

    Help me before I explode (or is that implode?!)

    I can't help directly, but can you not work it out from the manual?

    If it says that you should use a delay of 0 (for example) and your speakers are 3m away, but a delay of -10 if they're 6m away, then the receiver is playing the sound before it appears on the screen so the sound reaches you at the same time.

    Just guessing though, and it depends what examples are given in your manual.

    Thanks Bursar

    The problem with the manual is that it doesn't mention +ve and
    -ve values for delay (which are available in the settings on the amp) it merely talks about delays of 5ms, 10ms etc. Hence my uncertainty as to whether i am actually setting delay or advancing the output.

    If it only had settings of -5ms etc, i would accept that is delay, or even if it just had +ve values, but I can go from -30 to +30 values.

    just to add, its not actually obvious from the audible effect when i try these out - probably due to my untrained ear

    You would usually have to delay the sound to the centre speaker if it was placed closer to you than the main speakers. + for adding a delay and - for reducing it e.g +5ms gives a delay time of 5 ms. That's how I understand it.
