A:AnswerHi! The headphones indicator is the small "H" over the display. If this H is lighting up, you can try to troubleshot it by plugging and unplugging a pair of headphones (in case this is a small glitch). For further help, please contact us on the link below.

A:AnswerYes, There is a CD input, and you can hook up the TT and cassette player to one of the two aux inputs, but you may need a phono amp to power the TT. You can get these from about $10.00 to as high as your budget will allow.

A:AnswerHi, Kilo.
Thank you for letting us know about your inquiry. There are no replacement remotes for this Receiver since none were manufactured to be sold separately. I recommend to search online for a compatible replacement.

A:AnswerYes. You would use one of the aux inputs. Depending on your TT, you may need a phono amp, or if it is a newer model, it may have an amp built in.
