Description:
- NX1s upgrade version.Use OP+BUF structure,increase thrust to 150mW (32 ohm),150% of NX1A , easy to deal with the huge headset. NX1s minimum distortion down to 0.0005% (300 ohm), frequency expansion to 20-100kHz, bottom noise down to 3uV (low gain), NX1s has leapfrog challenge strength.Hi-Res, Audio standard sound quality
- Nx1s is a high performance headphones amplifier gain and a selectable mega bass, it was designed for all types of music player to improve the quality of power output and drive a motorcycle helmet.
- Output power:the higher the better.
- Distortion degree: the lower the better.
- Bottom noise:the lower the better.
- CD sound quality can reaches 20-20kHz requency fresponse,Japan Hi-Res Audio standard requires 20-40kHz frequency response,its highest frequency is twice as the CD good quality.NX1s frequency response is 20-100kHz.The NX1s size is 75 percent as the former.Headphone amps is smaller and more easy to carry.
- All aluminum shell,MACBOOK surface treatment.Aluminum turnery and tread wheel increase the friction operation.
- There are two bosses on the panel.Separate gain,bass gain.
- You can select high gain or low gain.Normal volum uses low gain.Low noise,weak input signal uses high gain,high magnifying ability.
