Ray Teret, 72, has been accused of a total of 32 offences involving 14 youngsters and one adult, who was 17 at the time of the alleged offence.
He was charged with 15 counts of rape of a female under 16, one count of rape, one count of attempted rape of a female under 16, six counts of indecent assault of a female under 16, three counts of indecent assault of a female under 14 and one count of gross indecency with a child under 13.
Teret, from Altrincham, also faces two counts of conspiracy to rape a girl under 16, one count of possession of extreme pornography, one count of possession of prohibited images and one count of possession of an indecent image of a child.
The former pirate radio DJ spoke only to confirm his name and address during the Manchester City Magistrates' Court hearing.
He stood with his hands clasped in front of him listening as the lengthy list of charges were put to him. No pleas were entered.
He was bailed until November 15, to appear at Manchester Crown Court.
David Lees, prosecuting, said the offences were historic and the Crown would not oppose bail but he asked for conditions to be applied.
Emma Hassell, defending, asked for bail as Teret, who has been under investigation for 11 months, had attended the police station when required.
His bail conditions are that he must not apply for international travel documents, live and stay each night at his home address, sign in at his local police station three times a week, have no unsupervised contact with any person aged under 16 and not contact directly or indirectly any of the complainants in the case.
Teret was first arrested and bailed in November 2012 with another man on suspicion of historic rape following an investigation into three separate claims of sexual abuse.
At the time Greater Manchester Police emphasised that the accusations were not linked to Operation Yewtree, the national inquiry into abuse by disgraced TV presenter Savile, with whom Teret worked and once shared a flat.
As part of the Teret investigation, William Harper, 65, of Stretford is charged with conspiracy to rape a girl under 16 and attempt rape of a female under the age of 16. Alan Ledger, 62, of Altrincham is charged with indecent assault of a female under 16 and aiding and abetting the rape of a female under 16.
Both Harper and Ledger are due to appear before Manchester City Magistrates' Court on 30 October.
Teret left court with his solicitor without comment and was pursued by reporters to a waiting taxi.
The Operation Yewtree police inquiry into allegations of historic sexual abuse linked to the entertainment industry has seen a number of high-profile arrests.
They include former BBC Radio 1 DJ Dave Lee Travis, 68, who last week pled not guilty to 14 counts of indecent assault and one of sexual assault between 1976 and 2008. He will be tried on January 14.
PR consultant Max Clifford, 70, has pled not guilty to 11 counts of indecent assault. Veteran entertainer Rolf Harris, 83, will be tried in April for indecent assault and making indecent images of a child.
