BBG-1002-UDX-DSP Function Menu List and Descriptions
(continued)
Allows selecting audio channels to be inputted to any pipeline DSP
function(s). Also provides Gain, Mute, and Invert controls for each input
channel.
Note: Drop-down source choices depend upon whether input mixer or
output mixer positioning is selected. Input mixer choices are primarily
basic card input audio sources; output mixer choices are primarily card
audio bus channels.
(Option +DSP-UPMIX-LA only) Provides controls for setting up upmixing
of any normal PCM stereo pair into 5.1 surround sound audio which in
turn can be applied to six user-selectable channels or further DSP
processing.
• Mode selects from Auto (detect content on surround, else force
upmix), Bypass, or Always Upmix.
• 5.1 Detection Threshold adjusts the threshold at which selected
channels designated as C, LFE, Ls, and Rs are considered to
have viable content, or at which signal levels can be considered
insignificant when upmixer enable is set to Auto. Setting affects
automatic enable/bypass of 5.1 upmix function.
• Center Width adjusts center channel content (in terms of
percentage) applied to L and R channels.
• Minimum setting keeps all L+R (mono) content confined to
center (C) channel, with any center channel content removed
from L and R channels.
• Higher settings progressively blend respective L and R mono
content back into L and R channels, with 100% setting resulting
in center channel level going to zero and L/R channels
becoming normal L/R channels containing some mono content.
• LFE Level allows gain to be added to derived LFE channel.
• Surround Depth adjusts surround channel content (in terms of
percentage) applied to Ls and Rs channels.
• Maximum setting results in greatest surround channel levels.
• Lower settings progressively diminish surround channel levels,
with 0% setting resulting in no Ls or Rs level, with Ls and Rs
content progressively folded back into L and R, respectively.
• Dimension adjusts the perceptual spacial image in the surround
channels to be accentuated or diminished.
