The front input acts like a standard guitar amp/pedalboard input. When the input is set to SPDIF, this input can still function to output a DI (unprocessed) signal for overdubs, depending on the output mode selected.

}}

=== Return ===

}}

The return input is designed for the return signal from the effects loop or from the profiling process.

=== SPDIF ===

}}

The SPDIF input can be used to connect digital gear, mainly used for [[Kemper KPA Reamping|reamping]].

== Input Settings ==

=== Input Selector ===

This selects the active input used to feed the KPA's signal chain. Choices are Front, Alternate, or SPDIF Reamp. In SPDIF Reamp mode, the Front input is still active, able to record DI tracks.

=== Noise Gate ===

''While this setting is not visible in the Input block, it is actually part of it - it locks with it and it stored and loaded in Input presets.''

The "Noise Gate" on the input is not a traditional expander, but a kind of noise remover. Normally, I am wary of such things, but it works well here - it can lower the noise considerably without hurting the tone or changing any dynamics. Still, it can leave noticeable artifacts in the tone if set too high. It also can make the noise you expect to hear from a high-gain amplifier sound a little strange.

=== Clean Sense ===

Clean Sense controls the volume balance between low and high gain settings for a particular rig. The KPA has a somewhat unusual way of handling a clean tone, which can be confusing. The KPA can only capture a profile at a certain gain setting but allows editing the gain on the resulting rig, all the way from completely clean to fully-saturated, mushy distortion. To do this, each amp profile contains a kind of parallel pair of clean and distorted profiles. From about 4 and below on the Gain knob, the profiles are blended inversely, and these can have a radically different volume level depending on how hot the pickups you use are. Clean Sense can be adjusted to make these roughly equal.

I don't adjust the gain parameter for the profile on the fly (I use the guitar's volume knob instead), so I don't need to worry about balancing the volume of clean vs. distorted within the same rig. If you do want to change the rig's Gain parameter, such as by an expression pedal or MIDI, then you should check both for input clipping (as explained above) as well as using Clean Sense to level the volume between the rig with gain at 0 vs. 4. If these things are in contention, you'll have to make a compromise.

=== Distortion Sense ===

Distortion Sense functions as a gain level adjustment. When Input is locked, Distortion Sense allows quick adjustments from guitar to guitar to get a similar gain level (when desired). It's also useful if you find a profile pack where you'd like to demo the profiles quickly at different gain settings.

=== Reamp Sense ===

When using the SPDIF Reamp input source, this parameter replaces the Clean and Distorted Sense parameters. It is simply a level adjustment to the DI track and works similarly to Distortion Sense.

== Physical Outputs ==

=== Main ===

The Main Outputs can be sent as dual 1/4" or dual XLR, carrying a full stereo signal. They can be connected to a DAW or PA, as well as the effects loop return of a guitar amp, or the input of a dedicated power amp.

=== Monitor ===

Monitor Out is similar to the Main Outs, but it is a single 1/4" connection, capable of only carrying mono audio. It can be used to connect to a stage monitor, or it can carry a different tone than the Main Outs by changing the [[#Output Settings|output settings]]. It also has an option to disable the Cab block, which lets you use this output through a guitar amp and cab.

=== SPDIF ===

'''The KPA's SPDIF I/O must operate with the KPA as the master (or clock source), and is limited to 44.1 kHZ''' (although 48 kHZ may be in the works).

=== Headphones ===

The Headphones output is on the front of the unit. It is similar to the Main Outs but designed for headphone levels. There is also a Headphone Space setting that only applies to it, intended to add a reverb/reflection type effect that may feel lacking when using headphones compared to open air speakers.

=== Direct Out/Send ===

The Direct Out/Send output is a 1/4" out whose function depends on rig settings. It can function as a direct out (DO) for making a DI track for reamping. Or it can be used as the effects loop send. Or in Profiling Mode, it is used to feed the real amp's input.

== Output Settings ==

=== Modes ===

Each physical output can be assigned to operate in one of the following modes. These typically

* Delay/Reverb Wet

|}

=== EQ ===

The Monitor and Main Outs have global EQ that can be applied to them on pages 3 and 4 of the Output block. These can be used for venue-level adjustments.

=== Link and Levels ===

On page 2 of the Output block (and page 5 for SPDIF), you can manually set the levels of the different outputs. The "link" check boxes above link the output's level to the Master Volume knob, allowing them to be changed on the fly but retaining the relative differences in levels between linked outputs.

=== Other Options ===

There are two "Aux In" options used to blend the auxiliary input (which depends on the input source selected) with the KPA processed signal. This can be used to adjust the volume balance when jamming over backing tracks.

The Headphone Space check box determines if the Space setting applies only to Headphones or to all outputs. When checked, the Space setting changes to "Headph. Space".

== Effects Loop (Profiling Send/Receive) ==

The same connectors are used to send and receive the test tone used during the profiling process.

== Other Connectors ==

=== USB Slave ===

The square-shaped USB connector on the KPA is used to connect the KPA to a computer, in order to use the [[Kemper KPA Rig Manager|Rig Manager software]].

=== USB Master ===

The rectangular USB connector is used to connect a USB flashdrive, which can be used to [[Kemper KPA Storing/Recalling Rigs, Presets, and Backups|create backups or import rigs/presets]].

=== Network Port (RJ-45) ===

This port is used to connect to the Kemper Remote.

=== MIDI ===

The KPA features MIDI in, out, and through. For more on what the KPA is capable of doing via MIDI, see [[Kemper KPA External Control#MIDI|External Control]].

=== Switches/Pedals ===

You can connect two switches or expression pedals up to the KPA via the Switch/Pedal inputs. For more see [[Kemper KPA External Control|External Control]].
