UPMAX® Upmixing
Preset and Format Controls
UPMAX processing is largely based on presets. Several factory presets are included which can be used as-is or serve
as starting points for a custom user preset.
Preset Menu
Use the Preset dropdown menu (8-2C) to choose a preset. To save any changes as a user preset, click on the
Save As button (8-2D) and name the new preset. You must refresh the browser window to see the new preset in
the Preset list.
Input Format Menu
The Input Format menu (8-2B) is used to specify the channel format of the source audio. If the input format
matches the selected output format (as selected with the Output Format control) the unit will pass the signal
through as-is without additional processing. Input options include:
Auto Detect: In this mode, the unit continuously monitors the input signal to determine its format and will
♦
automatically switch to one of the processing modes below (Stereo, Stereo + Dialog, or 5.1)
Stereo: Stereo content will be upmixed to the desired output format
♦
Stereo + Dialog: Stereo content will be upmixed to the desired output format, while a dedicated dialog input
♦
on Channel 3 will be passed through to the Center output
5.1: 5-1-channel content will be upmixed to the desired output format
♦
Pass-through: Pass-through will pass the input signal directly through to the output with no additional pro-
♦
cessing; this can be used as a "soft bypass" function as the signal still runs through the upmixer and therefore
incurs the same amount of latency as it would if it was actually upmixing a signal, thereby preserving A/V
sync and avoiding lip sync issues
Output Format Menu
The Output Format menu (8-1A) determines the output channel configuration. Output options include:
5.1: Provides a constant 5.1-channel output from Stereo, Stereo + Dialog, and 5.1-channel input sources
♦
5.1 Legacy: Like the standard 5.1 output, it provides a constant 5.1-channel output from Stereo, Stereo +
♦
Dialog, and 5.1-channel input sources but with upmixing that is sonically closer to the previous UPMAX
algorithm used in the Linear Acoustic UPMAX v4 upmixer and the algorithm employed in the various Linear
Acoustic AERO®-series processors
7.1: Provides a constant 7.1-channel output from Stereo, Stereo + Dialog, 5.1-channel, and 7.1-channel input
♦
sources
7.1+2: Provides a constant 7.1.2-channel output from Stereo, Stereo + Dialog, 5.1-channel, 7.1-channel, or
♦
7.1.2-channel input sources
5.1+4: Provides a constant 5.1.4-channel output from Stereo, Stereo + Dialog, 5.1-channel, or 7.1.4-channel
