The Kemper Profiling Amp offers a technology that is unlikely any other on the market. ''While it functions similar to a digital modeler and multi-fx unit, it has a number of unique features with their own terminology, that can be very confusing for a novice.'' This page breaks down the unique terms used to make discussing the product more clear.
* '''Amp Profile''' - a profile designed to emulate the response, compression, basic EQ, and distortion of an amp. This kind of profile is created by all profiling processes. It may be modified by the merging process.
* '''Cab Profile''' - a profile designed to emulate the phase relationships and frequency response of a mic'ed cabinet (or the general sound of some device). Generally, these are only created as part of a Studio Profile, but it can also be created from a Direct Output profile. This can be modified by the merging process.

== Rig ==
A '''Rig''' is essentially the same thing as a "patch" on other digital modelers or multi-fx units. It contains profile data, as well as all the effects types and settings that were dialed in on the virtual signal chain. Even input settings can be saved per rig, if not globally locked. A KPA rig is designed to represent everything necessary to emulate a real-world "rig", from stompboxes to amp, cab, microphones, and outboard processors. Rigs can be saved and loaded inside the KPA's internal storage, backed up to USB, and exported/imported as .kipr files through the Rig Manager software. It contains amp/cab profiles, although these rarely may not contain any real data and/or be disabled. For example, after creating a Direct Amp profile, the cab block in the resulting rig has no data - you have to copy/paste a cab from another rig for the block to actually do anything.

== Performance ==
A '''Performance''' is similar to what many other devices call a "setlist". It is a group of rigs/patches organized into specific banks and slots (1A, 3B, 8C, etc.). This is useful for playing live, so that rigs can be organized in a way that makes the most sense for the gig. Multiple performances can be saved and loaded, allowing different rigs and organizations to be used depending on the gig. For instance, one performance might be useful to demo different rigs at practice, while another may be ordered to follow an exist setlist for a gig.

== Pure Cab ==
'''Pure Cab''' is a feature introduced in FW 3.1 that attempts to reduce comb filters and other issues introduced by close-mic'ing a cabinet, so that profiles sound more like the "amp in the room". It currently consists of a checkbox to enable/disable it and an amount value inside the Output block (which is global); however, there are plans to move this to the Cab block in the future in order to allow per-rig settings.

== Stomp, Stomps, Effect, Effects ==
Kemper's virtual signal chain consists of 4 effect blocks in front of the amp and cab profiles. These are collectively known as '''"Stomps"''', while each of the individual blocks is called a '''"Stomp"'''. Similarly, there are 4 effects processed after the amp and cab profiles, known collectively as '''"Effects"''' and each individually as an '''"Effect"'''.

This can be confusing when dealing with presets. Stomps presets are presets for all 4 effects in the Stomps section. Effects presets similarly include all 4 effects in the Effects section. Yet, the KPA's backups and formatted USB layout include a folder called "Effect" (in addition to "Effects"). The Effect folder stores all presets for individual effects, whether they are located in a Stomp slot or Effect slot.
{{top}}
== OS ==
Kemper officially uses the term '''OS''' (Operating System) for its firmware (FW) updates. The file used to update the KPA internal software is called kaos.bin (Kemper Amplifier Operating System). This makes sense from a technical point of view, but it is unconventional when referring to devices that are not computers or smart phones. This can be particularly confusing when discussing Rig Manager, which bridges a traditional Mac or Windows computer to the KPA; as Rig Manager versions are dependent on both the OS version of the computer and OS version of the KPA.
{{top}}
== Soft Buttons ==
The 4 buttons above the KPA's onboard display are known as '''soft buttons'''. This is because they have no default usage - instead their use is determined completely by software. When they can be used, you will see a text button directly below them on the display. They are most commonly used to flip switches for effects, but can also be used to change filter and sort options while in Browse mode.
