Element Channel Fader Issues


Element faders fail to respond properly.  This could be a failed fader pot, but there is also a known glitch in Eos family software that effects element (original, gold consoles, not black/silver element 2).


  1. Power on your console and navigate out to the shell (or prevent it from entering the application by clicking on the timer).  Go to settings/maintenance and click on the face panel test.
  2. While monitoring the affected fader on screen, move the fader up and down and watch for errant or jittery movement on screen.  If you don't see anything, try gently wiggling it sideways as well as the faders beside it.  If you hear any clicking, that indicates a failed pot even if you don't see any errant movement on screen.  But the failed pot may also be the one beside the fader you had an issue with as it can sometimes effect nearby pots. 
  3. If this is the case, please contact ETC or a qualified technician to set up a repair as the pot will require replacement.
  4. If you saw no indications of failures in step 2, check your version.  There was a known glitch in Eos family software from version 2.1.0 to 2.5.2 that causes QUICK channel patched fader movements to fail to be recognized.  To confirm the issue, go into the application where you can see the effect of any fader movement on the tombstone channel screen.  Slowly raise all the faders of one row up to a random assortment of about 1/3 - 1/2 up.  Now, while paying attention to the screen, move them all down as quickly as possible.  If this is a software issue, you should see one or more fader levels fail to go to zero, but it may take a couple of tries to see the glitch.
  5. If you are using a version in this range, we recommend upgrading to the latest compatible version.
