Kemper Powerhead on a 4 Ohm Bass-Cab

  • greetings... has anyone tried the kemper powerhead on a 4 Ohm Bass-Cab yet?


    I did a DI profile of a friends SVT VR and I didn't dare to try it on the 4 Ohm 8x10.


    I know that it shouldn't be a problem but I wanted to ask if there any experiences of you guys.


    Best wishes

  • I used mine with a 4ohm guitar cab with no issues, so I'd say connect it up, turn it on, turn the master low and go from there.


    "While we are recommending 8 or 16 Ohm cabinets in combination with our built-in power amplifiers, it is techncially completely safe to use 4 Ohm cabinets.
    However users should be aware of some facts and apply the following best practices.


    Normally the built-in power amplifier would deliver significanty more power loaded with a 4 Ohm cabinet. But its power output
    is technically limited to 600 Watt, which is exactly the maximum it can deliver, if an 8 Ohm cabinet is connected.
    As soon as the power output exceeds 600 Watt, the power amp (not the Profiler) switches off for a short period of time. After about one second
    sound recovers.


    Therefor if you connect a 4 Ohm cabinet, you should adjust your volume so that the power amp never reaches its 600 Watt limit. If it does, it wouldn‘t damage
    the Profiler, but perhaps accidentally interrupt your solo play. Also for health reasons we strongly suggest to be very cautious with such volumes.
    Keep in mind: A 4 Ohm cabinet is normally significantly louder than an 8 Ohm cabinet given all other parameters stay the same.


    For the future we are planning a few firmware enhancements, which will increase the visibility of the power amp performance."
