Product Details

Product characters:

  • A970 is a portable earphone power amplifier is a high performance, the built-in high performance power processor and a power amplifier, and can be connected with various audio player and mobile phone on the audio signal processing, amplification, the output can drive all types of headphones, so as to enhance the audio amplifier power, improve the quality of the amplification effect.
  • Products can also be connected to the computer for sound amplification function.
  • It is easy to use, no need of special operation and use. The internal circuit of the amplifier output in the form of the capacitor, which can effectively avoid the internal circuit fault on expensive headsets harm, to insert the headset, sound source may generate impact sound (electrolytic output capacitors internal charge effect on the headphones and produced), the shock due to lower energy, no adverse effects on the headset, use find the following suggestions according to operation can effectively reduce the impact sound: firstly, the amp volume knob to the minimum, the sound and the amp connection, first open the audio, then open the amp, 5-10 seconds after the earphone insertion, sound is played according to adjust the volume knob to the appropriate place to.
