The optical is in the same slot. You must turn it on in the menu to active the optical recording.
im thinking about buying a iRiver iHP 120 and everywhere i go it says that it supports both optical and analog in/out and so i went to the store to check it out and maybe buy it. But it seemed to me that all it had was the analog in/out and an analog in/out cord... Is the optical in those same slot? Do i need an adapter or is some kind of cord also included? Thanx!!!
