Basically i just bought a set of decks and a mixer and they arrived today. I got a pair of 1210 mk5 and a VMX 200 mixer. It wasnt the mixer i origionally wanted, but they were out of stock of that one so i got this as a replacement. My problem is that it seems the crossfader is reversed. Ive checked the wiring and thats all fine, the headphones function perfectly on the right channels, just the crossfader thats wrong. Anyone got any idea how to sort this?
