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 different audio player and Mobile phone on the audio signal processing, amplification, the output can drive all headphones, in order to use the audio amplifier power, improve the quality of DeVerking effect.
Products can also be connected to the computer for sound reinforcement function ......
The product is easy to use, no need for special operation and use. The internal circuit of the
Amplifier output in the form of the capacitor, which can effectively prevent the internal circuit error on expensive headsets damage, to the headset, sound source can generate impact sound (electrolytic output capacitors internal charge effect on the headphones and produced), the shock caused by lower energy, no adverse effects on the headset, Use to 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 the volume button to the Right place to ......
