Insert CD1 into the disc tray on your left and CD2 on the right.
Flip the output switch on the left of the headphone option. Listen and find a track on CD1 to begin your mix. Do the same on the right to pick your second song.
Push the cross-fader all the way to the left of the mixer. CD1 plays through the speakers and CD2 outputs to your headphones.
Speed up or slow down the tempo of the music on CD2 by using the pitch slider to match the music on CD1. Use the jog wheel to skip a little bit forward or back to fine-tune your mix. When the two beats are in sync, you are ready to add CD2 to the speaker output.
Push the cross-fader to the middle of your mixer to get both CDs playing at the same time. You likely need to continue to make adjustments to the pitch slider and jog wheel to keep the two CDs in sync.
Push the cross-fader all the way to CD2 after playing both CDs for a time. CD2 is now playing through the speakers. Use your headphones to cue up a third CD on the left of your CD turntables.
