About the MultiMix-12FX 
The MultiMix-12FX—a 12-channel, 2-bus console—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. Only a few years ago, you wouldn’t have been 
able to buy a mixer this powerful for such an affordable price. Just 
take a look at the key features listed below, and you’ll see that you 
have just made an incredible addition to your home studio or live 
setup. 
The MultiMix-12FX gives you just about everything you need to 
create polished, professional-sounding mixes When designing this 
unit, our goal was to give you as much control over your mixes as 
possible without requiring a wealth of extra equipment. That’s why 
we added tools like the digital effects processor and the mic 
preamps. And with a multitude of  ways in which to connect other 
equipment and instruments, the MultiMix-12FX offers endless 
possibilities.
