The second Season of X Factor started on 30 August 2011. The auditions were held in April/May 2011. The show was broadcast every Tuesday and Sunday (only the Auditions and the Superbootcamp). The Judges were Sarah Connor, Das Bo and Till Brönner . There were four phases: Auditions Bootcamp Judge's House Live Shows This year twelve acts had been a part of the live shows, and not nine. Furthermore, from the first to sixth live show the judges decided which act had to leave the X Factor. In the final were three acts. Selection process Applications and auditions The first appeal for applicants for series 2 was broadcast during series 1 on 9 November 2010. Auditions in front of the judges for series 2 took place in Cologne, Berlin, Munich and Hamburg. After the acts sing in front of the judges, they could be eliminated or go through to the Bootcamp. The auditions were broadcast on 30 August, 4 September, 6 September, 11 September, 13 September, 18 September and 20 September 2011. Superbootcamp The episodes of superbootcamp were broadcast on 25 September and on 27 September 2011. It showed 150 acts attend to the superbootcamp. The acts were split into 3 groups, 16-24s, Over 25s and Groups, in which to perform at Mitsubishi Electric Halle, and each group was given one song by the judges: the 16-24s sang "Born This Way", the Over 25s sang "True Colors" and the Groups sang "Could It Be Magic". The judges then went on to cut over 80 acts, but called some soloists back, who were asked if they were interested in forming groups. All agreed and were workshopped to see which singers would work well together. They formed two groups. Then eight groups of each category were built and they fought in a battle, only one act of each duet came into the next round. Sometimes the judges end both through, but sometimes no one got through. The judges then chose the top 24 acts, based on these performances. Judges' houses Judges' houses, the final part of the selection process, was filmed in the summer 2011. The episodes were aired on 4 October 2011 and on 11 October. Judges were given their categories at the end of the "Superbootcamp". Brönner the Over 25s, Connor the Groups, and Das Bo the 16-24s.
