Contestants who make it through the auditions are paired by the judges to face off in a duel. The first contestant to sing, sings with the wall up and sets the benchmark for the second contestant. The second contestant sings with the wall down. If the second contestant betters the first contestant's vote total, the wall rises and the second contestant is through to the next round while the first contestant is eliminated; if the second contestant fails to raise the wall, the second contestant is eliminated and the first contestant is through.
