Warm tips:
Not inlcude power adapter, recommend to use original high-quality power adapter above 5W. 
For example: the current should be above 1A if use DC 5V while need above 0.5A if use DC 12V power adapter.

Features
  • Adopting innovative circuit design, DC 5-20V wide input working voltage, the amplifier circuit can always work at a high voltage of 26V, and the background noise index is excellent. With wide frequency response extension, excellent transient response, excellent purity and transparency, and good dynamic range.

  • Adopting original TI-NE5532 classical op amp and transistor expanding current circuit, using 1300mA large current output transistor working in class A status, with ultra-low distortion, and the sound is warm and delicate, full and mellow.

  • Pluggable op amp socket design, convenient to upgrade different op amps and bring much DIY fun and playability for audiophiles. Smooth and mellow sound, suitable for listening to vocals or string music, classic or pop music, and even with unique charm when playing rock.
