Audio Aero Prestige SE....

You may have inadvertently pressed the Pre button on the remote, this button disables all transport functions and you are left basically with DAC and preamp functions only.

Press the CD/Pre button on the remote, this will enable all remote control functions and the player will operate properly as a player + preamp.
Then press Standby, wait ten seconds and power up the player. The player now has memorized the new setting and will power up as a full function player.
I hope this helps

Sorry for the late answer.
You need the original Audio Aero remote to activate the CD/PRE function, not the optional universal remote with LCD screen, it has only basic functions stored in memory.
I suggest that you call the seller, a dealer or Audio Aero and get an original remote.
