Akai Force Master Output - Sub frequencies are cut

Hello everyone!

I'm preparing a live set with my Akai Force, where I will use both Audio tracks, like sample and loops, complete tracks (mastered and released) and Midi ones.

The master output of my Akai is missing a lot of sub frequencies. There's like a cut till 40-50hz and so the track are playing very thin and look like filtered.
When I play the same song in Ableton (or wherever) I have all the presence and the frequencies that are missing .

Do you know if I can fix this inside my Akai Force? Can you help me?
Thanks in advance!!

Also, ask yourself very carefully what you'll be playing through that will deliver a lot of sub below 40Hz. Very few audio systems will deliver that with any reliability? A tuned $500,000 club audio system? Even those are usually not great that low.

Assuming the hardware outputs are not damaged.
I suggest running it thru an analog mixer & just adding some low end.
I know this is not ideal but I find a good small mixer is a key tool to keep around at all times . . . . . . . .
