Sturdy and reliable, the CDI 300 MP3 plays MP3s, CDs, and CD-Rs and includes must-haves like sampling and fader "Q" start (when used with compatible American Audio Q-Series mixers). Cue points and samples can be instantly recalled using the unit's 4 flash start sampler buttons, which can each store up to 5-second samples. Also features seamless loop, tempo lock (master tempo), S/PDIF digital output, and anti-shock memory. It provides a range of ±4%, ±8%, ±16%, and up to ±100% "Hyper" pitch control. MP3 features include advanced cueing with track searching by frame (not by each second), quick MP3/CD recognition, and folder search. The display shows track (song) title and artist when an MP3 disc is played.
