The Topping NX1A (NX1 upgraded version) has been designed for MP3/MP4/mobile phone/computer that can not get best effect of high impedance from the headset due to the low power.
NX1A keep same circuit and component of NX1 to keep a same sound. But after modifing other part to save power, NX1A’s playback time up to 150h, that’s 50% improvement of NX1. It takes less than 3 hour to fully charge the battery. Even 5 minutes charge could provide 10 hour playback.
Its USB charging port has been enhance to be able to use standard Micro Usb cable for charging
* 0.000015% Distortion
* Splendid combination of Amplifier
* The topping NX1A use high performance chips, designed by TI CO,Ltd which is for audio
* amplification and can bead to reach the extreme distortion degree index of 0.000015% almost zero distortion.
Classical designed circuit
* Op-amp circuit still adopted the mature classic op-amp +buffer design.
* The best balance between high quality and reliable lasting dyrability.
* high frequency low resistance capacitance, very low loss and resistance
* NX1A voice is as brilliant as Steinway piano which is with 50 years history.
Innovation Power Supply Design
* USB intelligent charging.
* 1000mAh large-capacity lithium polymer battery makes the battery life can reach max 150 hours
* Full play to the op-amp and guarantee the good performance.
* Drive high impedance headphones with enough dynamic level range.
* Can adapt to the charge output of computer USB port and variety of Plugs.
* Automatically adjust the suitable charging current.
Humanized Function Indicators
* With Power LED & Charge LED indicator.
* The overall thickness less than 13mm.
* Upgrade with gain control and bass boots functions to perfectly match with different resistance and sensitivity headphones.
