=== LFC (Low Frequency Correction) ===
Starting in FW 2.5 (?), the KPA included this parameter. With FW 3.2 (?) forward, it is permanently on with no option to disable it. 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.
The parameter is a little confusing because by default LFC is turned on. There is a checkbox to turn it off called "LFC Off". So, if the checkbox is checked, that means LFC is turned off, and the KPA will function as it did before FW 2.5 (?).

=== Erase Non-Favorites ===
Page 16 is called Rig Management and has a single button to erase all profiles stored in the KPA that are not marked as favorites. I recommend not using this button since Rig Manager can more easily be used to delete the desired rigs. If you do find yourself wanting to use this, be sure to do a backup to a USB drive first.
