Hi, on my new ddj flx6 gt, I have a constant interference noise in my headphones (hdj x7), when using rekordbox or not there is constant noise when headphones is plugged in the controller (jack 6.35 and 3.5mm)

I tried others headphones and there is the same noise. Also, I tried whith others computers but same results...
