Note: Although Prime 4 can play
tracks that have not been analyzed
yet, pre-analyzing them allows its
features to work most effectively. We
recommend using the Engine Prime
software to configure your music
library on your SD card or USB flash
drive before connecting to Prime 4.
See the complete Engine Prime User
Guide to learn how to do this.
