256 Onboard Alesis Effects


Whether you're mixing the church choir or a heavy metal band, give your mix a professional edge with 256 onboard 24-bit Alesis DSP effects. Choose from room and space delays, small and large hall acoustics, plate and spring reverbs, flangers, choruses and more. The ZMX124FX USB offers 16 variations of 16 professional effects from which to build, tweak, and dial in your sound.


USB Audio Interface


Capture your live mix with your laptop and computer recording software by simply connecting a USB cable to the ZMX124FX USB. This USB-enabled professional mixing console features a USB port that streams two channels of 24-bit audio out to your computer (Main Mix or Sub Mix 1/2). With the ZMX124FX USB you can record band rehearsals, club gigs, speaking engagements, worship meetings, and any other live performance reinforcement situation. What's more, this USB connection is bi-directional so you can also stream audio from your laptop to the ZMX124FX USB for audio and music playback!


High headroom, low noise


With the ZMX124FX USB we took a no-compromise approach where the purity of your mix is concerned. This compact mixer brings a standard of quality to your performances that you expect to find in mixers costing twice as much. All Alto Professional ZEPHYR ZMX mixers are designed with high headroom and ultra low-noise, discrete mic preamps so you always get the full dynamic range of your mix every time.


Visualize your mix


We designed every ZEPHYR ZMX mixer with your performance in mind. Sometimes venues are dark and it can be hard to see what you're working with. Alto Professional solves this problem by not only color coding each section of the mixer, but also by using brightly colored knobs so that you can easily find what you need to adjust before you ever lay a finger on the mixer.  Our blue, red, yellow and white pots are instantly easy to identify in dim lighting. LED indicators for output level, peak, and phantom power also assist in making sure that you have multiple visual cues that compliment everything you're hearing.
