If you are picky about your musical selections, investigate the track programming logic on any player that you are considering. If the interface is not intuitive, or if it involves too many keystrokes, that player may not be for you. Some changers allow you to change several discs while one plays. Good ones will accommodate up to five or six units. Many higher-end CD players have a direct digital output either optical or coaxial, or both.
Optical jacks require a special fiber-optic cable.
Highly specialized cables are available for coaxial outputs, though any standard cable will do, especially a high-bandwidth video cable. The CD synchro function makes digital recording easier by simultaneously triggering the playback and recording machines. Disc Capacity Disc capacity refers to the amount of discs a CD player can hold at once. This display feature tells you which track is playing and the number of tracks the disc contains. The calendar graphically displays the disc's tracks and often indicates the specific number of track playing.
