Introducing the Rugged, Simple to operate, Built too Last - MX120A Dual Channel Remote Mixer

The MX120A is a Friendly End-User Sound System interface. Simply plug in a Microphone, MP3 Player, Laptop, Ipod or CD player, and turn up the volume! The MX120A can be placed anywhere in a facility. It's unique daisy chain ability allows multiple units to be wired together with only one home run. Saving on wire and installation costs!

Key Features

  • Dual Channel
    Two separate inputs, low impedance microphone and auxiliary (music) inputs.
  • Expandable to Four or a Six Channel Mixer
    Up to three MX120A’s can be daisy chained to form a four (2 MX120A's) or six channel mixer (3 MX120A's).
    MX120A's can be installed side by side or up to 100 feet from each other. Eg. Stage left and right.
  • Voice Enhance Circuitry
    Reduces low frequencies to enhance voice intelligibility.
  • Vandal Resistant Lockable Case
    Surface or flush mount optional protective case for added security.
