    Introduction About the iMultiMix 8 USB The iMultiMix 8 USB mixer is the latest in the large family of Alesis audio mixers. We’ve come a long way since the 1622 mixer we first built in 1989. Since that time audio technology has grown in leaps and bounds, pushing up quality and driving down prices.
