I use a two notes captor 16 to grab DA profiles and it works really well.
But the Captor isn't just a DI Box. It's an attenuator/Speakersim (or if you want to look at it this way: a load)
The Kemper DI Box is much cheaper, but still needs a Cabinet as a load. The Setup looks like this:
you need to match the impendance between amp and cab. That's it.
The Kemper DI is just that...a DI box only. It does not attenuate or load down an amp and therefore needs a speaker cab connected at all times. You would match the ohms to whatever ohms your cabinet is.
- Speaker cable connecting your amps speaker out to “from amplifier”
- Speaker cable connecting Kemper DI “to cabinet” to your guitar cab input
- XLR cable connecting “to profiler input” to the KPA XLR return
From the Amp - Speaker out speaker in - Speaker Cable?
Yes
Then from the DI Through to the speaker Cab - Speaker Cable.
Yes
The Kemper DI does not adjust or attenuate the amplifier to speaker volume. The amplifier to speaker signal is passed through the DI, so the DI does not have impedance limitations.
The Kemper DI (like all speaker-level DI boxes) also has an XLR Output that sends a signal that has been separated from the amp to speaker signal.
The XLR Output is used to create a "Direct Amplifier" Profile.
correct. There will be no cab in this rig. You can use a cab from a different rig or an IR then.
Silly question: The point of a DI is to get the tone (from the complex impedance of the speaker) in the signal. So is a profile from a DI considered direct? Since it will be colored and sound like the speaker is in the profile? Asking for a friend 
EDIT: Ahhhh I read the other post about DIs. So some DIs let you turn off the speaker influence. I am too old. These youngsters and their fancy softwares with built in IRs confuse me. In my day the whole point of the IR was to get the speaker sound without a mic. But now it is to get the amp sound including the output stages.
It always pays to read posts on here even if not Kemper related.
