Using merged profiles with traditional cabinet

    Hi guys


    So I've been a Kemper user for alittle over a year (powerhead version) I've mostly just been using it with a traditional guitar (2x12 Marshall 1936) and disabling the cab button on the kemper, which worked fine.


    I've recently discovered merged profiles but I'm just struggling to get my head around them.


    I'm still wanting to use my guitar cabinet on stage (I just like to have that as a reference point) but go straight out the Kemper main into the PA.


    So I've turned the monitor cab off in page 2 of the output settings and left it lit on the front of the kemper for the front of house.


    My only concern now is I'll be getting a different sound out the front of house than what will be coming out my cab. I've seen that celestion offer an IR of my cab and I'm just wondering if I purchased them and loaded a cab sim of my actual cab into the Kemper, would what's coming out the front of house sound the same as what's coming out my cab? I know I won't get extact match but enough that itll be close to the sound?



    Thanks :)

    There are thousands of IR's of the same speaker, and even if the same microphone was used, they can be very different.

    When you or the sound technician mic your cabinet..the resulting sound is always different. So I guess these IRs will make your foh sound only a little bit more similar to your cabinet in the room sound, but maybe not. This is only an opinion, I dont know how representative of the whole cabinet (not the microphones and position) these IRs are.


    What I do, my recomendation is, to check the compatibility of the sound of your cabinet and the line out sound, a/b ing them (with headphone or flat speakers). If you dont have a very flat reference dont worry (if you know very well how it sounds) but better try several references just in case.

    Compatibilty I mean similar bass amount specially.

    Lately i am mixing the cabinet and the monitors of my rehearsal place, very close one from another and it is ok, nothing weird..and my favorite rig is an studio rig, i dont even know the speaker. Kemper does a good job spliting an studio rig, i can't notice when a rig is merged or studio through a cab.

    Merged profiles are often misunderstood by users. Merging is actually a process of subtracting the amp from a studio profile to leave just the speaker. It is done by making a Direct profile of the amp (the sound that the amp is sending to the speaker) and a studio profile (the whole signal chain capturing the sound of the mic in front of the cab). The Kemper then compares the two and create a new speaker only component. The new merged profile should now sound exactly like the studio profile when the cab section is eneabled and played through FOH or FRFR cab. But should also sound exactly like the real amp when played through the real speaker with the cab section turned off.


    Will this make your onstage sound exactly the same as the FOH sound? No because you’re not listening to the effect of the mic on stage. Will it make it REALLY close to the sound of your own onstage cab through a mic yes but only if you are actually using profiles that you made yourself with your onpwn amp and speaker.


    Basically the sound we guitarists are used to hearing on stage through a regular guitar cab bears little resemblance to what the audience are hearing through FOH because of the impact of the mic and FOH eq. The Kemper is no different when used with a traditional cab. If you want your onstage sound to be the same as FOH you need to go FRFR. However, if you feel the need to use a traditional guitar speaker because you like the way it sounds and feels on stage go for it. It is no different to what you were doing previously with a traditional amp sect up. Just enjoy the sound pn stage and trust the FOH engineer to make it sound good to the audience.
