Q - Simon's X R - Amanda's X U - Alesha's X P - David's X Z - blackout stage B - blackout stage and X's Left arrow - main stage (used everywhere besides Cardiff) Up arrow - second stage (used at the Cardiff auditions)
2013 was another year in which there were two stages used. The blue stage with yellow highlights was used for the Cardiff auditions that year, but wasn't seen on television for many acts. This was the last year where the X's flashed when all the judges had buzzed. Updated on 16/04/16: - New X design - Better buzzer sound
