The colors and brightness of not only the main display but also the buttons and LED collars around the knobs can be adjusted.
=== LFC (Low Frequency Correction) ===
Starting in FW 2.5 (?), the KPA included this parameter. It is extremely useful for metal tones where there is lots of low-end frequencies, especially on mutes. Essentially you get more/tighter bass with LFC turned on. If you look up older A/B comparisons of the KPA profile vs. the reference amp for metal tones, you can usually notice that the KPA tone sounds a bit brighter/thinner than the reference. Newer comparisons using LFC are virtually identical.
