The TOA MM700F Matrix Preamplifier from Toa Electronics is an all-in-one solution for multi-channel or multi-zone applications combining a 6×4 audio matrix and a DSP into one chassis. It is equipped with four independent line inputs, two mic/line priority inputs, and four outputs. Each output channel features 64 DSP preset selections for general equalizations, crossover for subwoofer, and EQ settings. The mic/line inputs offer first and second priority levels that can override at assigned output channels automatically or manually. All assignments and setups can be done by dip switches on its rear panel without a laptop or a PC.

The TOA MM700F matrix preamplifier is suitable for a wide range of applications that require multi-zone paging and/or background music distribution at restaurants, clubs, retail stores, schools, offices, factories, etc.


  • Four stereo-summing line inputs with matrix routing to four line outputs
  • Each line input has an input level adjustment and assign restriction setting for each output to prevent wrong routing selection
  • Two priority mic/line inputs with different priority levels for paging or other pre-recorded sources that can override the selected line input on assigned output channels
  • Each priority input also has input level, mute sensitivity, and mute hold time adjustments
  • Selectable DSP preset selections include general EQs, like loudness curves, TOA speaker EQs, and crossover settings to be used with subwoofers
  • Each output channel also has auxiliary line output to deliver audio to other systems
