Line Level Computer to Profiler?

  • How do I get a line level signal from my MacBook Pro to my Kemper Profiler Head?


    The objective here is to be able to hear what is playing on my computer through my Kemper. This lets me jam along to song tracks on the computer or learn new songs using various software programs.


    My computer has 4 USB C connections and one 3.5-millimeter headphone jack.


    Thanks for the help.

  • Not sure what you mean with "such and animal" :) but if you mean the cable than you can see one example here:

    Yes, that is what I mean. "What type cable?" I thought that was the right one but wanted to make sure.


    I have been playing for over 25 years but have always just plugged right into a good tube amp using no more than a couple of pedals.


    Now, I wonder if the input from the computer can be heard as well as the guitar input? I mean, at the same time.?

  • You also have 2 options for playback when using an interface and monitors with a DAW and desktop speakers. (1)You can play out to the monitors while the desktop speakers are playing (like a youtube song, etc.) at the same time, or (2)you can switch the computer playback to use your interface and monitors while playing your guitar through them at same time (more preferable).

  • Yes, this video is valid and it describes what we already talked. It is really important for you to spend some time and read cearfully Main Manual 8.5! In fact, there you can find almost everything.

    I got the proper cable to run line level output from my MacBook Pro to my Profiler head. Hooked it up as explained in the tutorial/manual.


    As I suspected, I can not run line level input and guitar to the same cabinet or headphone output. No matter what is selected in the Input Menu (in this case Aux In), the Front Input on the head will take priority and cancel the Aux In signal.


    This is clearly explained in another video tutorial here: "The Front Input will always get priority"


    Kemper Profiler Tutorial - Input Section


    The Tutorial I listed earlier in this thread on Aux Inputs and the one listed in this post seem to be contradictory.


    So how is it that one can "jam along with an MP3 recording" or anything else when the Front Input kills the Aux In signal????


    This is a simple task on my $200 Spark amp. Plug in the 3.5 mm audio cable and go. Want to send it all through your headphones? Pug them in. That is it. This thing is really getting frustrating. Not to mention, I still can not connect my MacBook Pro to the Profiler to update the firmware or transfer Rigs from Rig Manager. So far, one on one with Kemper Support has not been able to solve that issue either.

  • As I suspected, I can not run line level input and guitar to the same cabinet or headphone output. No matter what is selected in the Input Menu (in this case Aux In), the Front Input on the head will take priority and cancel the Aux In signal.

    You definitely can run a line level signal into the Aux input at the same time as using the front input for guitar. As per pages 123 and 124 of the manual. I can confirm it does work.

  • No, the front input does not kill the Aux signal. "The Front Input will always get priority" mean only priority of front input over alternative input. It has nothing to do with Aux input! I am pretty sure that you have to check your Aux settings in Output menu. Again read page 123 carefully.

  • Page 124: "For all other PROFILER variants, the Auxiliary Input cannot be used while you have an Effect Loop active in your Rig, or while you are in PROFILER Mode, as the physical inputs are needed for a different purpose. "


    I will try it again tonight. Perhaps this is the problem "Effect Loop active".


    The sound from my computer comes through external speaker and headphone just fine until I plug in my guitar to the Front Input. Then, it dies. Does this mean I can only "jam along" with a clean dry signal coming from my guitar?

    What gear do you have in effect loop? Couldn't you just use "onboard" efects and disconnect the loop? There is quite wide onboard effects offering. I own Stage, so I do not have this limitation.

  • Given that I use this capability live to play intro tracks, I know this works.


    Check the connections but sounds like you have your effects loop active. Just to comment - the Spark amp is a different beast designed for home practice. The Kemper is designed as a serious studio and live tool, so the focus isn't on using it to play along with songs. You are better to do this with a DAW as you will have more control over the mix.


    Obviously the connection to your Macbook and Profiler is nothing to do with this but part of your frustration. Suffice to say it is plug and play so I'll let support help resolve.

  • Finally! I got it figured out. I would have given up long ago if it had not been for those of you say that "it can be done".


    I got the proper cable and figured out how to set Input and Output controls to make it work.


    Thank you.

    Yes, the Spark is pretty much a toy but, my Suhr PT-15 IR is not. However, plugging Line In and Headphones to the Suhr work exactly the same as the Spark. It is way simpler.


    I sent Support my DebugLog.txt today so, maybe they will get the computer issue figured out as well.
