Kemper KPA Reamping
- For general principles, see Reamping.
The Kemper provides several features that make tracking and reamping easier and quicker.
SPDIF
The Kemper provides SPDIF input and output. To use SPDIF with your DAW, the Kemper requires being the SPDIF clock source, and must operate at 44.1 kHz. There are a couple quirks to this, depending on the input and output settings you choose.
Tracking DI's
The recommended settings for tracking DI's are to use your usual input setting - front or alternate. Use SPDIF output settings of Git/Mono L or Git/Stack. You can record both the dry guitar and wet ("amped") sound to separate tracks, by using mono tracks and setting the dry track's input to SPDIF L and wet track's input to SPDIF R.
Reamping
The dry track should output to SPDIF L. Switch the Kemper's Input Source (tap the Input button) to SPDIF Reamp - this only listens for the left channel of the SPDIF input. You can use Reamp Sense to adjust for any gain differences if your DAW has manipulated the dry track volume.
Depending on your output settings (if you have one of the Git options selected), the Guitar Input is still active while the Input Source is set to SPDIF Reamp. It will output to the left SPDIF field (Git) while the wet signal (Stack, Mono L, Mono, Mod L, Mod) will output to right field. This is useful for if you notice mistakes in your DI tracks while reamping, allowing you to punch in quick fixes without changing KPA settings. The SPDIF signal input to the KPA will never output to Git - only to the other options - so there's no worry of a feedback loop here. If a stereo wet output setting is chosen, then the Guitar Input is disabled, and the SPDIF output will use both L and R.
