Versatile Inputs and Outputs
The ALTO ZEPHYR ZMX52 is the perfect mixer for quick, easy setups with no hassle.

Choose the ALTO ZEPHYR ZMX52 as the audio central command for your live performances, home studio, or video suite.

High headroom, low noise
Just because the ALTO ZEPHYR ZMX52 is the smallest, most affordable mixer we make doesn't mean you have to make sacrifices. This compact mixer brings the same standard of quality to your performances as our top-of-the-line models. 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 everyALTO ZMX52 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 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.
