Description


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.

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.
