Proper setup for dual amps in mono?

[Dirty145]

Can anyone explain how to properly set up dual amps and cabs in parallel for a mono signal. I’m blending a plexi and ac30 and want to make sure my settings are right.

On the unit, do I want it set to Stereo, Sum L/R, or Copy L/R?

Should I still be panning IRs or amps and choosing Sum L/R?

What should the input select options be on the amps/cabs?

Do you want each amp to have its own dedicated cab(s) or will they share the same cab(s)?
Are you going to use both amp blocks at the same time or alternate between them?

Both of these will affect how you route and level the blocks.

"It" could be multiple things. Here are the simplest possible instructions.

1. Create a preset with two amps and cabs in parallel.

2. Set input Select on the amps to SUM L+R. Set Input Mode on the Cab blocks to "Left".
3. Set all Pan and Balance controls in the Amp and Cab blocks to 12 o'clock.

DONE. You now have parallel amps/cabs in mono.

Take care, that the cab
blocks you are using are phase aligned.

Thanks! So what should the setting be on the unit itself for output? Stereo, Sum, or Copy?

In that specific configuration, they would all give you the same output with the left and right channels being identical.
