Cambridge Audio 640Razur Dynamic Range Control, ProLogic IIx adjustments, Using the Tuner

Operating instructions continued

Dynamic Range Control

This setting controls the dynamic range of Dolby Digital or DTS movie soundtracks by compressing the dynamics in four stages to limit the difference in level between loud and quiet passages in the movie.

This can be a useful feature when watching movies late at night for instance. Four settings are possible:

DRC=0/4 No Compression (normal full dynamic range playback)

DRC=1/4

DRC=2/4

DRC=3/4

DRC=4/4 Greatest Compression (reduced dynamic range playback)

DRC can be accessed by the Dynamic button on the remote, DRC=0/4 etc is displayed, pressing the button again moves to the next setting. When finished make no adjustment for a few seconds and the 640R will save the settings and exit the menu.

Note: DRC only works for Dolby Digital or DTS source material which supports this feature.

ProLogic IIx adjustments

The following adjustments affect Dolby Prologic II or IIx processing (or post-processing) in Music mode only. Movie and Game modes where available are preset as part of their specification to match the encoding or provide a specific effect. These adjustments have no affect in these modes.

Pro Logic Setup

Panorama	: On
Centre Width	:	0
Dimension	:	3

Return To Menu : [OSD]

Panorama mode - A Prologic II/IIx mode that extends the front Stereo image to the surround sound speakers for a more enveloping experience. This mode can be either On or Off.

Centre Width - Allows gradual adjustment of the centre image from being produced only by the Centre speaker (Setting 0) through levels of being spread between the centre channel and Left and Right speakers to finally being produced by the Front Left and Right speakers only (Phantom Centre, Setting 7). Useful in optimising the Front/Centre/Right soundfield for best integration of the 3 speakers. Best tuned by ear.

Dimension - Adjusts the soundfield to be gradually shifted from the front of the room to the back to suit taste, speaker positioning and size of room. Setting 0 has the image furthest forward, 6 furthest back.

All three adjustments are a matter of personal preference, experiment for the settings that you prefer if you are using PLII or PLIIx decoding.
