TOA A2120 Mixer Amplifier, 120W 100V. 3x MIC inputs, 2x line. 70V & 4 Ohm outputs.

TOA’s A2000 Series Mixer and Power Amplifiers are designed to be highly cost effective solutions to the demands of PA applications. They offer high levels of performance and versatility and are well-suited for paging and background music in schools, offices, shops, warehouses, factories, houses of worship and large meeting spaces.

Three balanced/XLR3-31 type MIC inputs and two unbalanced/RCA pin jack AUX inputs, along with high and low impedance balanced (floating) speaker outputs and unbalanced REC outputs ensure operational versatility.

Phantom power and muting are available on MIC 1, along with tone control for bass and treble. Power, signal and peak indicators are provided.

Note TOA A2120 Mixer Amplifier is the analogue model with the following differences;

  • Contact closure muting on mic 1
  • High (70/100V line) and low impedance (4Ohm) outputs
  • 24VDC operation as well as 240VAC


  • 120W single zone mixer amplifier (analogue model)
  • 5 inputs; 3 mic (XLR) and 2 line level (RCA)
  • Contact closure muting on mic 1
  • High and low impedance output
  • 24VDC or 240VAC operation
  • Use optional MB25B brackets for rackmounting
  • Manufacturers Warranty of 3 Years
