Provides upmixing of any normal PCM stereo pair into 5.1 surround
sound. Requires the UMA-8242 option.
Note:
For any six channels selected for this function, the
Left
and
Right
channel selections always serve as the stereo input pair.
• Up Mixer Mode Control
Enables or bypasses upmixer as follows:
•
Auto:
Automatic enable/bypass of 5.1 upmix function as follows:
If detected signal level on
all three
of the selected channels
designated as
Center
,
Left Surround
, and
Right Surround
are
below
the level threshold set using the
5.1 Detection Threshold
control (described below), upmixer produces new 5.1 content
generated by the upmixer.
If detected signal level on
any of the three
of the selected channels
designated as
Center
,
Left Surround
, and
Right Surround
is
above
the level threshold set using the
5.1 Detection Threshold
control, upmixing is bypassed and the channels fed to the upmixer
pass unaffected to the upmixer outputs.
•
Always Upmix:
Manual enable turns on upmixer and overwrites
content on all six selected channels with new 5.1 content generated
by the upmixer regardless of original signal level or content.
•
Bypass:
Manual disable bypasses the upmixer. When bypassed,
the six input audio channels pass unaffected to the upmixer output.
• Upmixer Input Channel Selection
Separate drop-down lists for
Left
,
Right
,
Center
,
LFE, Left Surround
,
and
Right Surround
allow a stereo pair to be upmixed to 5.1-channel.
The example here shows selection of bus channels 1 and 2 as the
received stereo source (
Bus Ch1
and
Ch 2
for
Left
and
Right
drop-down
list selections in the Upmixer Selection tool).
Using the setup shown in the example, when upmix is active (either forced
upmix or auto-enabled) the
Upmix L
thru
Upmix Rs
channels comprise a
5.1-channel upmix of the input stereo pair. If any content is present on the
monitored C, LFE, Ls, or Rs input channels whose is above a
user-defined level threshold (Bus Ch 3 thru Ch 6 in this example), all six
inputs channels pass through the upmixer, with upmixing bypassed.
Upmixer output channels
Upmix L
thru
Upmix Rs
are available as
sources for the card audio output routing.
