Ultra-low distortion precision linear feedback circuit (PLFC), distortion as low as 0.00008%!
Ultra-low noise power supply design, so that the output noise is as low as 1.3uV (APX555B measured value, not equivalent);
Ultra-compact design, suitable for desktop headphone system;
High precision low temperature drift resistance, its performance is not affected by temperature;
High quality relays and popless sound design;
High precision low noise 256 level relay volume control;
*In order to make the volume more linear in actual use, the extra levels are shielded. 4 Watts into 16 Ohm,2 Watts into 32 Ohm;
20 Hz to 500 kHz Frequency Response;
3 gears of gain control, for IEM or headphones;
High, medium and low three gears can switch gain control;
The headphone amplifier has DC,comprehensive protection such as overvoltage and thermal protection;
Use high-efficiency and ultra-low noise power system.
