What are the advantages of Class H Loudspeaker Amplifier compared with other types of amplifiers?

1. High efficiency and energy saving
Class H Loudspeaker Amplifier dynamically adjusts the power supply voltage by monitoring the input signal amplitude in real time. For example, low voltage is used for power supply when the signal is low, and high voltage is switched to when the signal peak is high, which greatly reduces static power consumption. Its efficiency can reach 70%-90%, which is much higher than Class AB (about 50%-65%) and Class A (about 20-30%), and close to Class D level. Class G requires multiple sets of fixed power supplies to achieve voltage switching, while Class H reduces system complexity through continuously adjustable power supplies, reducing the cost and volume problems caused by multiple power supplies. The output stage transistor voltage drop of Class H amplifier is minimized, avoiding the energy waste of Class AB amplifier at low power.

2. Sound quality and linearity
Class H Loudspeaker Amplifier inherits the linear amplification principle of Class AB and eliminates crossover distortion through dynamic bias technology. Class D is prone to high-frequency noise and EMI interference due to switching modulation, while Class H can achieve high-fidelity output without complex filtering. In music or theater systems, Class H can accurately handle instantaneous large dynamic signals and avoid the transient noise problem of Class D during high-voltage switching.

3. Heat dissipation and stability
The efficient operation of Class H Loudspeaker Amplifier reduces energy loss and has lower heat dissipation requirements than Class A and Class AB. At the same power, the volume of Class H heat sink can be reduced by 50%, which is suitable for compact equipment. Class G may generate local high temperature due to multiple power switching, while Class H optimizes heat distribution through continuous voltage regulation.
