Sturdy and reliable, the CDI 300 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.
