Hi,
Connect the output of your Kemper Profiler to the input 3/4 on the back of the AudioFuse (since there is already preamps on the Kemper, there is no need to go thru input 1/2 of the AudioFuse). And that way you can keep Input 1/2 free fir your bass and your mic.
Connect your monitors to the Speaker A L/R output.
Regards,
Matthieu
