9931-EMDE Function Menu List and Descriptions
(continued)
Shows activity status of upmixer processing as follows:
• Auto Mode - Currently Upmixing: With upmixer enable set to
Auto, indicates selected channels designated as Center, LFE, Left
Surround, and Right Surround are clear for use (as described
above); upmixer is currently up-mixing received stereo pair and
overwriting the six selected channels with new 5.1 upmix.
• Auto Mode - Currently Bypassed: With upmixer enable set to
Auto, indicates selected channels designated as Center, LFE, Left
Surround, and Right Surround have content (such as existing
original 5.1 or other content); upmixer is bypassed (disabled) and
allows normal passage of six selected channels.
• Upmixing: Indicates upmixer is manually enabled (set to Always
Upmix) and is currently up-mixing received stereo pair and
overwriting the six selected channels with new 5.1 upmix.
• Bypassed: Indicates upmixer is manually disabled (set to Bypass)
and is currently passing all selected channels unaffected.
Individual controls select the relative crossfade transition speed between
Upmix to Bypass (going to inactive; from 5.1 to 2.0) and Bypass to Upmix
(going to active; from 2.0 to 5.1) when upmixer enable is set to Auto and
the active threshold (as set by the 5.1 Detection Threshold control) is
crossed in either direction.
To suit program material and production aesthetic preferences, several
choices are available as shown to the left. Slower settings allow for a
more gradual transition between modes, however with a longer interval
before levels stabilize. Faster settings conversely allow for a smaller
interval before levels stabilize, however with greater perceived
abruptness.
