Allen heath Zed12 FX no sound

Hi,

Just bought new speakers and fetched all my hardware from their boxes to set up my new studio.

I have connected an Elektron digitaks into the line in of the mixer and the speakers with their XLRs but i cant get any sound out of it.

  1. the elektron produces sound, i have checked it with headphones, it is connected to the Line in with a jack.
  2. The level lights are not on neither on the channel or the main output
  3. No mute is pressed, no solo buttons on this mixer either or busses
  4. I have tried both PFL and normal

Is there something i am doing wrong? what else should i check, i remember that my mixer worked straight away when plugged but not no lights and no sound what so ever.

Any help?-
