NEOsystemes continuously develops and imagines proprietary solutions.
Our high frequency switching know-how enables us to reach highest class-D and power supply efficiency, resulting to ultra compact modules. 


Neosystemes Direct Output Floating amplifier

Since 2012, Neosystemes provides power amplifier modules with direct output floating replacing transformer-based solutions which also combines following major advantages:

  • Full bandwidth
  • Continuity of service with a short circuit to earth
  • Low impedance output and output offset possible which help for all monitoring systems




High grade class-D amplification

Our class-D technology employs a loop control working on any load and on all the audio bandwidth without damping network

  • Output impedance down to 5mOhm
  • Noise floor down to 70uV
  • Power bandwidth up to 80kHz
  • High SNR up to 116dB
  • THD down to 0.002% at 1kHz
  • ...

High efficiency switching power supply

Our innovative AC/DC and DC/DC switching topologies offer the lowest consumption even at idle

  • High efficiency up to 97%
  • Bi-powered power supply with single transformer
  • Universal input PFC (power factor correction)
  • Synchronous rectifying for better efficiency
  • Ultra wide DC input voltage solution for embedded system
  • ...

Transformerless power output

Our direct output technology enables a lighter solution and better intelligibility

  • Direct 70/100V output for PA application
  • Working on any load thanks to our control loop
  • Output isolated from input audio substitutes former transformer solution
  • Ready for EN54 system certifying
  • SNR >95dB (unweighted)
  • ...
