6. Equalization (EQ): Use the HIGH, MID, and LOW knobs on each channel to shape the tone of the input signal. Turn clockwise to boost frequencies, counter-clockwise to cut.
7. Panning: Use the PAN knob to position the sound of each mono channel in the stereo field (left or right).
8. Headphone Monitoring: Adjust the PHONE knob to control the volume of your headphones.
