Portable Headphone Amplifier
The Topping NX1S is the ideal solution that is easy to use and extremely efficient, giving your earphones a whole new dimension. Replacing the famous NX1A it pushes the limits exceeding the characteristics requested for the High Definition files with a bandwidth of 20-100KHZ. Thanks to a shorter track circuit the NX1S is 25% more compact than the old NX1A model.
En somme, le NX1s est un produit inhabituel qui s'illustre par ses performances dans les domaines difficiles (bruit et distorsion) mais pas dans les domaines faciles (réponse en fréquence).
The NX1S uses only quality components, studied to offer you optimal performance. Thus, you find EPCOS capacitors as well as an ALPS potentiometer. The fully revised and corrected circuit now includes operational amplifiers TI OPA1652 and LMH6653 with unit gain.
Thanks to the switch on the amplifier, you can precisely adjust the gain for better dynamics, the desired bass level and obtain improved sound.
Designed with CNC numerical control the matte surface in aluminum and its laser engraving offers a modern and elegant design. The design with flap on the sides protects the connector and the potentiometer knob In a pocket or jacket, so the volume can not vary in level inappropriately.
