The onboard CD drive allows you to simply insert a disk and sit back while the unit copies it into FLAC and adds tagging information which it locates using Amazon as its database. In the case that all of your files are already stored on a hard drive, transferring to the media player is as simple as a “drag and drop” method over your home network. The speed of this process will depend on your equipment and step by step instructions for this can be downloaded on our website in the Music Server setup guide.
