Panning

[BigEasy504]

Last night I noticed I'm not hearing my panning results. I see the pan knob in Pro Tools 10 moving when I turn the knob on the Tascam DM 3200 but not hearing the outcome from the speakers (KRK Rokit 5 & 8” Monitor and 12” Subwoofer). Some advisement would be highly appreciative

Is your mono button pressed (lit up)?
