CA20 3 Steps Class H Transformer Power Amplifier

1. Class H Circuit 
2. High Efficiency intelligent cooling system 
3. 2 ohms stable on long time load 
4. 3U standard chassis, with high strength steel structure
  • CA20

  • Sanway


CA series power amplifier covers 2U 3U height. CA series is faster reaction rate, higher damping coefficient, richer functionality, More advanced protection system. CA series has excellent cooling wind path design, compact and solid Mechanical seismic performance, excellent components.

CA series amplifiers can bear 2ohm stereo, 4ohms bridge load, suitable for driving linear array speaker system. It is suitable for large flow performances, the band, DISCO, nightclubs and other occasions.


1 . Large efficient transformer, bulk capacitor filtered power, have extremely low distortion in full load, more powerful low-frequency control and more clear sound.

2 . 3U standard chassis, with high strength steel structure.

3 . 8Ω; 4Ω and 2Ω all can be worked for a long time, suit for most regular demand.

4. Low harmonic distortion (THD<0.05%), and perfect frequency response (20-20kHz).

5 . Professional structure design make sure noise is enough low.

6. Dual channel progressive cooling system, build in thermostat. Electronic fans cooling the amp from rear to front, avoid overheating.

7. Adopting SMT Surface Mounting Technology, ensure good consistency.

8 . Soft-start, overcurrent, shortcircuit, overheating, DC, distortion, voltage limiting protect the amp from the damage of man-made and environment.


This device is suitable for the following occasion: Music clubs, meeting rooms, music halls, dancing clubs, multifunctional conference halls, outdoor small live shows, family gathering , wedding party,school broadcast , station and airport broadcast, etc.
