UPMAX® Upmixing
Center Width Controls
These controls define the routing of the LF and HF bands across the Left, Center and Right Channels. Used in
combination with the Mid-Bass Crossover frequency control, the provide the ability to craft the image of the Front
Channels in a way that maintains a direct sonic-visual association of dialog while providing a pleasant and wide
image of the phase-correlated elements. Though values are expressed in a decimal format, they easily correlate to a
percentage value (0.00 = 0%, 0.05 = 50%, 1.00 = 100%, etc.).
The LF Center Width control (8-4B) determines the amount of LF audio routed to the Center versus the Left
and Right Channels. The HF Center Width control (8-4A) does the same for audio in the HF band.
A setting of 0% sends all audio in the respective band to the Center Channel, while a setting of 100% sends it to the
Left and Right Channels only. Intermediate values provide a blend to create any desired mix.
