In addition, a full balanced design was used to minimize noise interference, and Power Factor Correction (PFC) was used to completely eliminate surge noise.
Optical protection sensors are employed for the audio amplifier unit and protection circuits, which completely eliminate physical and electrical contact for maximum sound quality.
Since capacitors typically found in amplifiers can introduce sound-coloring, a DC feedback loop design was implemented, and no capacitors were used.
Furthermore, the input buffer, driver, and output stage were completely isolated from the audio amplifier unit in an independent design to eliminate cross-interference. The outstanding structure uses separate constant-voltage circuits to eradicate any deterioration in sound quality.
All of these features were carefully selected and implemented to ensure the most accurate interpretation and playback of complex audio data transmitted from the AK500N.
