Advanced UPMAX Menu
The Advanced parameters are included for audio experts who wish to dig deep and tweak settings for very
specific applications or demanding tastes. They are not required for most users and are accordingly not
displayed by default.
NOTE: Some advanced controls - specifically those relating to additional side and height
channels - will be grayed out if they are not applicable to the selected output format.
Cycles per Octave
The Cycles per Octave control (6-6A) defines the number of teeth there are in one octave of frequency
change of the comb filter. The comb filter is used to separate different frequency components of the input
signal to aid in steering sounds in the surround field.
Minimum Comb Filter Frequency
The lowest frequency of the comb filter is set by the Minimum Comb Filter Frequency control (6-6B). For
most applications, this should be set at or near the same frequency as the Mid-Bass Crossover frequency.
Comb Filter Level
The Comb Filter Level control (6-6C) sets the overall level of the comb filter. This control can have a
significant impact on the movement of audio between the front and rear channels, with higher values
rendering a greater sense of depth. In nearly all cases, leaving this control at its default value will result in
the most pleasing soundfield.
