Alesis AirFX - 3D EFFECTS PROCESSOR FOR DJs

(This text is machine translated) Connect the airFX to any line-level sound source and speaker system. Then move your hand, or any other body part through the invisible 3D sphere formed by our patend pending Axyz technology. You can move in any direction; up or down, right or left, or in or out, to twist any sound in an infinite number of ways. The slightest movement of your hand tweaks the tones of our ultra-modern DSP system and turns your tunes inside out!
