1. Use US imported embedded high-power control chip system, use PreAmp non-balance to balance, PostAmp balance transmission amplification. With a wide range of voltage applications, you will get an enhanced enjoyment of high, middle and low-frequency music quality! The built-in loudspeaker protection and power-on delay circuit kill the impulse sound in Power On or Power Off. Characteristic: PreAmp uses non-balance to balance circuit to control the IC distortion, keeping high fidelity and dynamism. We use a lot of imported components in parallel and high-frequency low-impedance components to create a super-power digital power amplifier and power supply operated in high frequency. This enhances the sound quality. The embedded chip with the function of loudspeaker and overcurrent protection can avoid the impulse in Power On or Power Off, further smooth the signal transmission and ensure better effect of sound quality.

2. Max. capacitor array at the same level is 13, 200 microfarad Philip BC capacitor, input coupling uses the top-grade BP capacitor among Japan Nichicon MUSE for audio, use air core inductance featuring fine tone as audio filter output.

3. Input switch chip and loudspeaker protection made of high-quality components.

4. Use the global standard for mobile communication 110-240V power supply with sufficient power and small heating. Use STMicroelectronics imported embedded control chip with as high as 320W output power. Playing music at fingertip, integrated functions of listening, playing and watching. User-friendly operation, high-quality HIFI music, HIFI sound reproduction. Listening to music, playing game, watching movie HIFI, tiny and portable. Ready to be applied via PC. A wide range of applications such as drawing room, mobile, CD, VCD, DVD, company, supermarket, car.

5. The stereo system via high-power digital amplifier allows for fingertip operations on portable devices including listening to music, playing games and watching movie. Dynamic music will please your ears. Powerful, high dynamic, good strength, full voice, wide sound field and powerful low-frequency show considerable thickness. Magnetic, fine and full voice. High frequency shows good performance. Particularly of high frequency, moderate lightness, suitable for a long time of listening, good stereo sense of middle frequency, wide sound field, clear sound quality, full and warm. Good box-free sense ensures the sound with permeation. The circuit is enabled with the functions of overcurrent, overheating and output short circuit protection.
