Connecting to speaker cabinet

  • Hello everyone,

    First of all, I am completely new to kemper and guitar cabs in general. I just bought my first guitar cabinet, an orange 2x12 (ppc212) and connected it to my kemper from the left main output to the rear input jack on the 2x12 using a speaker cable. The sound is alright, but quite quiet compared to my expectations, even with the master volume, rig volume, and guitar volume cranked. Switching around the connection to the monitor output helps with volume, but way muddies up the low and mid range frequencies.

    Plugging headphones into the headphone jack has resulted in far superior tone and volume than the sound coming through my guitar cabinet.

    I feel like I'm missing something obvious with connecting the kemper to my cabinet, maybe in settings or even general connections.

    Any help is appreciated.

  • Evening,

    Assuming you have the powered version, use the speaker output (rated at 8-16 ohms).

    If you do have the powered version, might be worth investing in some studio monitors and connect via balanced TRS cables.

    Hope this helps...

  • If you have the powered head or rack, you need to use the speaker output jack (the one with the red ring on it) to drive a passive cabinet. If yours is not a powered version, you need either powered monitors or a power amp to drive your cabinet. The main outs are instrument/line level, and are not meant for driving passive speaker cabinets.

  • Hi There,

    Is that right?

    I have a 4x12 Celestion Marshall Cabinet 8-16 ohms

    and it sounds really low, increasing the master monitor volume just craps the sound...

    and with any amp like a fender vibrolux it sounds great, flat frequencies and low volume

    Kemper does not work with passive cabinets????


  • The powered Kempers (with an integrated power amp installed) will work with passive cabinets, but the standard models do not have a power amp in them and therefore cannot drive a passive cabinet. The easiest way to tell is to look at the back panel-if you see a jack with a red plastic lock nut on it, that is the speaker out jack and you have a powered version. If you do not see that jack (it's on the same side of the panel as the IEC power cable jack), then you have a non-powered version and cannot drive a passive cabinet without adding an external power amp.
