Music | Music mode is for use with any stereo music recording. As the optimum decoding |

Dimension
(This setting can be adjusted only when Dolby Pro Logic II Music mode is selected.)
‘Dimension’ allows you to adjust gradually the soundfield either towards the front or towards the rear. If a recording is too spacious or strong from the surrounds, it can be adjusted ‘forward’ to get a better balance. Likewise, if a stereo recording is somewhat too ‘narrow’ sounding, it can be adjusted toward the rear to get a more enveloping, immersive result. We recommend ‘Dimension’ is set to 0 for normal use.

With Dolby Pro Logic II decoding, dominant centre signals come only from the centre speaker. If no centre speaker is present, the decoder splits the centre signal equally to the left and right speakers to create a ‘phantom’ centre image. The Centre Width control allows variable adjustment of the centre image so it may be heard only from the centre speaker; only from the left/right speakers as a phantom image; or from all three front speakers to varying degrees. We recommend ‘Centre Width’ is set to 3 for normal use.
