Compression
Allows compression of the audio stream to be turned on or off, where ‘On’ is intended for ‘late night’ listening when large volume changes are not desirable.
Turning compression on increases the volume of the quiet passages and decreases the volume of the louder passages, i.e., the total dynamic range of the audio is reduced. Normally, however, this item is set to “Off”, to disable compression.
This menu option affects both the analogue and the HDMI outputs (although note that the HDMI output is affected only when carrying
Compression is available only on Dolby Digital recordings.

Music | Music mode is for use with any stereo music recording. As the optimum decoding |
| method varies according to the recording, Music mode allows user adjustment of |
| the processing characteristics; information about adjusting the Music mode by |
| using ‘Dimension’, ‘Centre Width’ and ‘Panorama’ controls can be found below. |
Matrix | The Matrix mode is the same as the Music mode except that the directional |
| enhancement logic is turned off. Matrix mode may be used to enhance mono |
| signal by making them seem ‘larger’. |
Dimension
(This setting can be adjusted only when Dolby Pro Logic II Music mode is selected.)
‘Dimension’ allows the user gradually to adjust 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.

Centre Width
his setting can be adjusted only when Dolby Pro Logic II Music ode is selected.)
ith Pro Logic II decoding, dominant centre signals come only from e centre speaker. If no centre speaker is present, the decoder splits e centre signal equally to the left and right speakers to create a hantom’ centre image. The Centre Width control allows variable djustment of the centre image so it may be heard only from the entre speaker; only from the left/right speakers as a phantom age; or from all three front speakers to varying degrees. We commend ‘Centre Width’ is set to 3 for normal use.
