Note:
The AutoMAX-II
TM
algorithm is supported by firmware version 1.3.1.0 and later. Firmware version 1.3.0.0
supports only the AutoMAX-I
TM
algorithm. The AutoMAX-I
TM
algorithm does not support the upmix-to-pass
and pass-to-upmix transition speeds.
Follow Metadata mode
This mode may be useful for sources that switch between stereo and 5.1. The
Coding Mode
parameter in the first
program of the Dolby metadata will set the Operating Mode between Pass and Upmix modes.
Note:
In
Follow Metadata
mode, the metadata generator will be automatically turned ON when the upMAX
TM
module is upmixing to provide a valid metadata stream for the upmixed audio content. The generator content
must have been previously configured with valid 5.1 metadata parameters. When the upMAX
TM
module is set
to
Pass
mode by the incoming metadata stream, the generator will be automatically turned OFF to let the
incoming metadata stream pass through. Refer to
Generator Automated
mode in the Dolby metadata panel
section for further details (page

).
If the
Coding Mode
parameter (in the Dolby Metadata panel) is other than 3/2 (i.e. 5.1 channels) or 2/0 (i.e. stereo
channels) or if the selected metadata path does not carry metadata, the Operating mode will follow the Reversion
Mode pull-down.
Coding Mode (Metadata):
Operating Mode:
3/2
PASS
2/0
UPMIX
1+1, 1/0, 3/0, 2/1, 3/1, 2/2, or metadata is not present
Reversion Mode
The
Reversion Mode
pull-down sets the default Operating Mode to: Pass, Upmix, Last Valid (Last valid
Coding
Mode
), AutoMAX.
Adjustments
The “surround field” can be adjusted with the Center channel Width control and the Surround channel Depth control.
The bass enhancement signal for the LFE channel is derived from the Left, Center and Right channels. The LFE
checkbox and LFE Channel Level (%) slider control the LFE output.
Latency
The upMAX
tm
processing latency is automatically compensated by the card.
Note
: when in UPMIX and AUTOMAX modes, the last channel pair of the output channels selection (channels 7-8,
15-16, 23-24 or 31-32) are reserved for future use and muted.
Note
: The upMAX
tm
works with PCM audio. If non-PCM audio like Dolby-E or AC-3 is fed to the module, it will be
ignored and silenced to prevent interference with the other PCM audio channels.
