Reply to S4: Can't monitor/cue with headphones AND use monitors, help me!

Hello,

My home DJing setup is a Traktor S4, a pair of Yamaha HS5 monitors and a pair of Sennheiser HD 25 headphones..

My issue is that I can't use headphones to cue tracks for some reason. It appears that my headphones AND monitors are the "main outputs", and the "monitor outputs" don't allow sound through either monitors or my headphones.

When I had CDJs, I had the monitors plugged into the mixer outputs and became my speakers, and I could STILL use headphones to cue (obviously..)

Now it seems with my new Traktor S4, I can't do both, and both monitors AND headphones are classed as "main outputs"!

Any help would be GREATLY appreciated!
