Hi, I usually run my Kemper into my Mesa 2:90 and out to (2) 2x12 cabs in stereo. If I want to only run a single cab with the same setup, how can I put a load on the other speaker output of the Mesa as it needs to be connected to a speaker when powered on.
Thanks,

You can use a dummy load like this:

or similar.
Price: 75 Euro
Inside of this box there's a resistance similar to this:

If you can use a soldering iron, solder the TIP of a MONO PLUG to one edge of this resistance,and the SLEEVE (Ground) to the other edge,using a speaker cable,and you'll have a dirty cheap, small and effective dummy load.
It's better to keep the volume of the channel that's not in use to ZERO.
The 2:90 doesn't need to be connected to another speaker . I have one myself and always use one side only into 1 cab. I think you have to set both the volume and presence to zero to stop the unused side from working. Check the Mesa manual . It explains what to do.
Excellent, thanks guys!

Thanks, you are correct, I have verified this in the manual.

IMO is more safe to put a load to the unused channel. As long as you keep the volume of that channel to zero it's ok to run it without any load,but because there's not a dedicated standby switch or any other kind of protection, if the volume by mistake is raised up, you risk to damage the output transformer and tubes.
This is a user error and if it will happens, Mesa doesn't pay the high expense to repair it.
