A:AnswerAny kind, through the 3.5mm headphone jack. As long as your CD player has a headphone out - and surely it does - you can get a cable to connect to the aux in of this unit.
A:AnswerLightning to whatever Apple called their older, larger connecter might work, but definitely headphone to AUX in would work, it just wouldn't charge your iPod.
A:AnswerFor 60 people, i don't know. Would you prefer loud music ? If not then this would be great for 60 people only because everyone will be able to hear each other speaking. I honestly wouldn't prefer you to use this device for a reception.
A:AnswerIs it blue tooth connected ? No it is not. It has to either be plugged in to the AUX wire or plugged in to the sound dock. But you can control it by the bose REMOTE.
A:AnswerNot sure, might put too much stress on the connector. And I doubt that it would be able to charge the iPad. IPhones need .5 amps to charge, iPads need 2.1 amps to charge. You could, and I do, use the auxiliary input with my iPad.
