PCM23 is a new high-efficiency and high-power switching power amplifier. Compared with the previous products, it has a breakthrough improvement in sound quality, which will bring you a new listening enjoyment. Using the second-generation Class I™ circuit topology, it maintains the style of a pure analog amplifier, while having high efficiency similar to Class D; using the third-generation regulated switching power supply, it can maintain stability even when the input voltage fluctuates greatly. Strong power output.


  • Using AI plug-in technology, so that each component has enough margin; in harsh environments, it can better resist the influence of accumulated dust on the circuit;
  • The power tube is directly installed on the radiator (no mica sheet and other medium insulation and heat conduction) to reduce the thermal resistance of the power tube, which can effectively reduce the instantaneous high temperature of the power tube;
  • High-quality adjustable potentiometers are selected to minimize the connection wires and interfaces between modules.
  • Efficient Class I™ amplifier modules.
  • The independent channels on the front panel have warning lights for temperature, protection and peak clipping.
  • Individual channel power indicators and -5dB / -10dB / -20dB signal indicator indicators on the front panel.
  • There is an input sensitivity selection on the rear panel.
  • There is a connection mode selection (stereo/bridge/parallel) on the rear panel.
  • High-quality adjustable potentiometers are selected to minimize the connection wires and interfaces between modules.
