The TOA MA-725F matrix mixer amplifier is a combined 6×4 audio matrix, DSP and 4ch Class-D amplifier. There are four output channels each rated at 250 watts, 70 / 100 volt line.

It's ideal for multi channel or multi zone applications providing 4 independent line inputs & 2 MIC/LIBE priority line inputs.

The MA-725F matrix amplifier performs matrix controls from 4 LINE plus 2 MIC/LINE level inputs to 4 output channels. Each output channel features 64 DSP preset selections for general equalizations, crossover for sub-woofers, or a variety of TOA speakers' EQ settings. 2 MIC/LINE inputs have 1st and 2nd priority levels which can override assigned output channels automatically or manually. 

Each output has independent DSP preset adjustment with input source matrix selection.

Rack mountable using supplied brackets.

  • 4 stereo-summing line inputs with matrix routing to 4 amplifier outputs.
  • Each line input has input level adjustment and assign restriction setting for each output to prevent routing selection.
  • 2 priority MIC/LINE inputs with different priority level for paging or other pre-recorded source which can override the selected line input on assigned output channels.
  • Each priority input also has input level, mute sensitivity and mute hold time adjustments.
  • Each output channel is equipped with 250W Class-D amplifier at 70V/100V output voltage selectable with independent DSP preset selection and 50Hz HPF for the protection of connected speakers.(*)
  • Selectable DSP preset selections include general EQs, like Loudness curves, TOA speaker EQs and crossover settings to be used with sub-woofers.
  • Each output channel also has auxiliary line output to deliver audio to other systems.
  • This matrix doesn’t need any PC programming or network connection for setup at site. (Maintenance purpose only)
  • Optional wall mount remote control, WP-700 can be connected via CAT-5 straight LAN cable to control the line input selection and output volume of each output.
  • Class-D amplifier has various protection features against over current, high temperature and short circuit of speaker lines at each output channel.(*)
  • Power supply with Power Factor Correction for reduced power consumption and world-wide operating range.(*)
