X factor Producer’s have today faced claims of SOUND fixing. Vocals we all hear every Saturday night from Jedward are drowned out by backing singers.  Bosses allegedly ordered the move using pre-recorded tracks by session singers an insider told The Mirror, in order to keep the tone-deaf twins in the show. Last night top brass admitted every act received “technical support”. But the extent to which the twins get help has left show workers furious.

An insider said “Every week session singers record backing tracks to some songs.”But soundmen are told to turn down the levels of the twins’ mics so their vocals are mostly covered by the backing singers. Often mics are so low the twins’ singing would be barely audible.”

The insider added that Jedward were lowered to a “ridiculous level” for their performance of Queen’s Under Pressure on Saturday. He said: “The only time levels were raised was when they were rapping.”The survival of ratings hit John and Edward has led thousands to complain X Factor has lost its song contest roots.A show spokeswoman said: “Contestants sing live and all are given equal technical support.”
