Miikerman touched on an interesting point: the EQ display is visible only for “custom”.
The yellow band display shows “Custom EQ” while the “sliders” are in the blue section. For all others (presets), the display is a menu only.
I think SanDisk opted to minimize confusion during the EQ mode. Note the “nav right” arrows available in all EQ menu choices. If the user presses the right button, in anything but “custom” that choice is held, and we are moved to the “equalizer” option within “settings”.
If “custom” is selected, a press of the “right” button moves us to the graphic EQ “sliders”, and the left/right navigation buttons will select a slider (band) while up/down will move the slider. The “hint” to the user, on what to do next, is the pointer below each slider. Pressing the center button finishes the selection, as will the “home” button.
If we try to navigate forward, or right, in any of the presets, we’re bumped back. Perhaps, in the future, a right press will yield a display of the preset settings (the sliders could look narrower, denoting a difference from the “custom” ones). Maybe if the up/down button is pressed while at this point, the yellow portion will show the preset names as the user scrolls between the choices, with the “custom” ones looking different- meaning user adjustable.
At least we have an EQ option! I am happy for that. I like the “jazz” preset personally…
