Down-sample
This needs to be set correctly if you are using an external audio decoder, receiver or D-A converter
connected to the co-axial or optical digital audio output.
Max 96K Choose this option if your external audio decoder is able to process digital audio
with a sample rate of up to 96kHz, or if you are not using the digital audio
outputs. This is the maximum sample rate present on DVD-video discs.
Max 48K Choose this option if your external audio decoder is unable to process digital
audio with a sample rate of up to 96kHz. This is the normal setting for this menu
item.
Note that this setting is relevant only to the output from DVD-video discs.
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 multi-channel uncompressed audio, not otherwise). The co-axial and
optical digital audio outputs are never affected by this menu setting.
Compression is available only on Dolby Digital recordings.
Pro Logic II
Dolby Pro Logic II decoding is designed to produce a 5-channel analogue output from two-channel
source material. This item can be changed only if the ‘Audio’ menu item (described above) is set
to ‘Bitstream/6 Ch’.
Set this item to one of the following. Due to the different recording methods used for movies and
music, it is recommended that the correct decoding mode for your source material is used to
obtain the best results.
Off No Pro Logic decoding is performed.
PL
Dolby Pro Logic decoding is performed. Dolby Pro Logic decoding is a legacy mode,
and we recommend using one of the Pro Logic II decoding options, instead.
Movie Movie mode should be used with material marked as ‘Dolby Surround’ encoded.
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 sound eld 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.
