Travis, whose real name is David Patrick Griffin, was living in Mentmore in Buckinghamshire but has recently moved house and was allowed not to give his new address in open court by Judge Anthony Leonard.
The prosecution case in his trial is due to open today.
Judge Leonard told a group of 40 potential jurors: "This case involves allegations of a series of indecent assaults and it is likely that you will find this an interesting case to try."
They were asked if they or a close family member has worked for the BBC, Chiltern Radio or Classic Gold FM, or has been involved with Scotland Yard's Operation Yewtree, under which Travis was arrested.
The potential jurors were also given a list of the names of witnesses in case they know any of them.
A group of 18 were chosen today, and it is expected that a panel of 12 plus two reserves will be sworn in tomorrow.
Before sending them away until 11am tomorrow, Judge Leonard warned them not to research the case in any way.
He said: "You will try the case on the information obtained here in this court and nothing else."
