Duo series (New)

Power Factor Correction is one of the main improvements made in the new Duo series. It allows a more efficient current draw from the main circuit, translating to higher out put power with lower power consumption.
Featuring a high-end, on-board DSP. The new Duo series offers an advanced, onboard DSP to fully tune system response. A feature rarely found in affordable power amplifiers in this range.


  • Class D power modules.
  • Built-in DSP with front panel control and Windows remote user interface software.
  • SAE Audio next generation Aluminum Body design.
  • SMPS power supply.
  • LCD amplifier status display.
  • XLR input and signal link connectors.
  • SpeakON NL4 and binding post output connectors.
  • Channel independent protection and clip warning indicators on the front panel.
  • Channel independent power and -3dB / -6dB / -10dB / -20dB / signal presence indicators on the front panel.
  • Ultra-lightweight weight design.
  • Fantastic sounding amplifiers with great specs.


  • Mobile / portable public address or monitoring amplification.
  • DJ sound system.
  • Small sized bar / café / lounge installation.
  • Applications with signal processing requirements.
