A:AnswerYou can hook it up to anything that accepts RCA jacks (that's what they called the connecting cables in the 90s. Has white and red ends that you match up on the CD player and whatever you have on the other end).
A:AnswerYou can load 5 CD's and this player will allow you play all 5 in continuum. No need to stop and switch and load the next dics. Extremely pleased with this Onkyo player.
A:AnswerI don’t have any book CDs to test but it plays MP3 so as long as the audiobook is in one of the formats listed, it should be no problem. It’s a great CD player. A big improvement over my old Sony player
A:AnswerI am unfamiliar with your current CD player. However, the Onkyo CD player is a very highly rated and professional machine in my opinion. I think it would serve your needs very well. You can’t go wrong with the price and the quality of this machine. That is my opinion. Good luck.
