I've fitted 2 exciters (Dayton DAEX25) to my sim racing pedals (Fanatec CSL load cell), via a 2 channel Nobsound amp. I have no idea what settings to use in Simhub and would appreciate some guidance.
chew go to ShakeIt Bass Shakers, on the left list thing.. then there's three tabs on the right, go to the middle one "sound output" and find your amp should be liek Speaker (USB2.0 Device) or soemthing liek that... click the switch on the right to turn it on, then click the white down arrow \/ in a circle thing on the left of your usb device to show the different channel configs, select 'leftright' (or mono if you did mono) then click "output tuning" bluebox above that and switch global gain control to 'generated sound gain'
now go back to the top tabs and click on effects profile tab
turn everything on but speed & speed with curving and anything red (leave off red and speed fx they don't exist or are noise) custom effect is nothing, leave it off... anything that sticks out you don't want, leave the sliders all at defaults for now... i turn the volume on the amp all the way up and keep simhub bass shaker master gain (on the very top all by itself) around 10-15%. your buttons will be different. at certain volume, the shakers will rattle every button in your rig. pedals are less rattly tho.
can also turn off more stuff, but i think simhub does okay with everything on. speed is just constant buzz tho and for fans not shakers or motors. if a certain effect is too much, just turn that effect gain setting down until it is to your liking, or just off completely, i think the defaults are good tho. it learns and adjusts to how you drive automatically by default. so, leave it alone for a few days... maybe backup the defaults before you mess with anything... you can test sounds in the efects profile tab just clicking the effect's down arrow and clicking test in the "live effects" box, some don't have anything to 'test.' if it shakes when you click test, should be good to open a game...
