The LXE Surface faders use digital registers in the programming to determine the position of the fader and feed that back to the software to locate the position of the fader on the console, however we have determined that in some cases, the analog tolerance of the fader design and build may fluctuate outside the point established by our software. To account for this, we have built a simple software adjustment into our LXE Surface Setup GUI for adjusting the Fader Off Threshold
If you find that your faders are not making it all the way to off even though you are lowering them to the lowest point on the module, then you can use this Fader Threshold adjustment to find that happy place where your fader is showing as landing at zero.
