Product description

The ZEPHYR ZMX122FX from Alto Professional is a compact, 8-channel audio mixer with 256 built-in digital effects presets, featuring inputs for both microphones and line-level signals such as drum machines and keyboards. Four of the channels feature balanced 1/4" TRS inputs, as well as gold-plated XLR jacks and microphone preamps, and two balanced 1/4" TRS stereo line-level channels are also provided. All six of these channels feature 3-band EQ, Pan, and Level knobs, as well as two Aux Sends. One of the Aux Sends is labeled for external monitors, and the other is dedicated to sending signals to external effects. The two Aux Return inputs, combined with the stereo RCA Aux inputs, make for a total of 12 input channels. The ZMX122FX also features two bus outputs: the Main Outputs and the Control Room outputs. Stereo RCA outputs are also provided.

The effects that are built into the ZEPHYR ZMX112FX are the product of a partnership with Alesis. They feature 16 different effects, and 16 variations of those effects, making a total of 256 presets to choose from. A 1/4" input on the rear of the mixer enables you to attach a separately available footswitch, so you can disable the effects with a tap of the foot. The effects can also be muted with a button on the face of the mixer. All of the knobs are color coded, to make it easier to operate the mixer in dimly lit environments.

    HI, Good day!

    Yesterday my ALTO ZMX 122 doesnt pick up the sound from my computer. I have been using this mixer for 2 years now. This is the first time i encountered no sound at all but its turned on. What i did i unplug everything and took off the cords and wires, i detached everything.

    I was planning to bring it to the technician but this morning I tried again hoping that it will be fixed somehow. So i attached and plug everything again and fortunately theres sound again, but i have one concern the led lights are not moving anymore. Should I be worried of this? Since the sound is ok now but the led lights are not working for some reason. I wonder what is the problem with my mixer.

    Hoping for your immediate response regarding this matter. Thanks a lot.

    Subject: Problem with my unit
    Date: 13.02.2021 10:48:41Name: Mark Sharp
    Hi, I’m having the problem of not being able to get power to my speaker, although the power light comes on the LED lights don’t show any life, I am trying to set the unit to a Marshall AS50R as apposed to my normal active pa speakers, I’m using the Y cable 1/4 inch jacks from the same channel as I would use for separate speakers is that correct. If I take the source from the guitar port on the amp and place that into the guitar port on the amp and the directly above fit the mic I can get sound through the amp but no controls of the volume or tones on the unit, I can control it from the amp, does this amp not work using the. Alto zmx122 , thank you
