sound delay headphones/speakers mac + djcontrol instinct + djuced

i have an issue using djcontrol instinct and djuced.

the speaker output is delayed by half a second, so lining up the mix in the headphones becomes a trainwreck.

Hello,

We cannot see your computer, so you must describe your computer configuration to get help on a forum: please describe EXACTLY
- what is connected on DJControl Instinct master output (dual RCA output on the rear panel of DJControl Instinct) - brand & model of the speakers,
- what is connected on DJControl Instinct headphones output (1/8" stereo jack on the front panel of DJControl Instinct) - brand & model of the headphones,
