Kemper Amps Forum

I'm about to buy an audio interface and I want to make the right decision in regards to I/O so I have to option to reamp with the KPA. First things first, has anyone found a preference between using the main outs (XLR or 1/4") vs. the SPDIF out? I've had other modelers with SPDIF and with those, the analog outs just plain sounded better (higher quality A/D maybe?).
Anyway, I figure I would have the Guitar -> KPA -> direct output to 1/4" analog in on interface (to capture the dry track).
Then I would ALSO have the KPA -> SPDIF out -> SPDIF in on interface (to monitor and possible record the KPA, stereo track in most cases)
When it is time to reamp, mute the affected stereo tracks.
Recable and take LINE OUT from the audio interface -> instrument input on the KPA.
As usual record this reamped KPA using the SPDIF out -> SPDIF in on the audio interface.
Is that right?

Quoted from "guitarnet70"

Everything correct, I have XLR to board (USB 2), not the 1/4, only difference.

Sorry, can you elaborate on this? When you say "XLR to board" do you mean you are using the MAIN OUTS (XLR) that go into your board (and then audio interface) vs. using SPDIF out on the KPA to SPDIF in on your audio interface?
That is the reason I asked if people are seeing any issues using SPDIF (in quality of tone - I have heard that SPDIF in general on the device is now working both in and out). One of the audio interfaces I am considering does not have enough 1/4" or XLR I/O for reamping so I would have to use SPDIF if I want to go with that particular interface.
Or are you talking about the DIRECT OUT/SEND? On the KPA it looks to be 1/4", are you saying you have a 1/4" - XLR cable that goes to your board?
Thanks!

ok perfect. I wonder if there is a way to keep everything cabled correctly between the recording portion and the reamping portion without creating some type of feedback loop? I will have to draw myself a diagram lol.

I think I have it figured out for my approach:
<TRACKING PHASE>
Guitar -> KPA instrument IN -> KPA XLR or 1/4" main out -> analog inputs on audio device (this is the full patch, for monitoring and/or recording stereo processed tracks)
-- > KPA direct OUT -> 1/4" analog input on audio device (this is for the dry guitar signal)

<REAMPING PHASE>
SPDIF OUT from audio device -> SPDIF IN on the KPA (I will have to set the DRY guitar track to route to SPDIF out which is sent to the KPA for "amplification"
KPA XLR or 1/4" main outs -> analog inputs on the audio device (record enabled)

I think I should be able to keep this cabling permanently and I don't believe I will have any feedback loops as long as I don't route anything through SPDIF output on the audio interface back into the KPA SPDIF IN until I'm done and happy with my take/DRY guitar track. You also mentioned the SPDIF can be muted from within the KPA as well which is cool.
EDIT: I guess technically I could use SPDIF IN and OUT to/from the KPA as well. Still worried about loops though, but as long as I don't send any SPDIF out to the KPA and always only send the dry guitar track via SPDIF to the KPA I should be good. That would also cut down on AD/DA conversion in my process above. I really wish someone would comment on how the SPDIF I/O is working and sounding vs. the analog outs.
During all of this I will also have the monitor out cabled to a power amp + cab (for now) and later probably an FRFR system.
Cool stuff!
