Features:<br />● PreAmp uses non-balance to balance circuit to control the IC distortion， keeping high fidelity and dynamism. <br />● 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. <br />● 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. <br />● 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.<br />● Input switch chip and loudspeaker protection made of high-quality components. <br />● Use STMicroelectronics imported embedded control chip with as high as 320W output power. Playing music at fingertip， integrated functions of listening， playing and watching. <br />● User-friendly operation， high-quality HiFi music and HiFi sound reproduction. <br />● The circuit is enabled with the functions of overcurrent， overheating and output short circuit protection.<br /><br />    Specifications<br />Primary Features<br />	 Model: A915                                                  <br />                        Design: Portable， Stylish                                                  <br />                        Supports: Loudspeaker                                                  <br />                        Functions: Stereo                                                  <br />                        Compatible With: PC， Laptop， Tablet PC， Mobile Phone                                                  <br />                        Connection: Wired                                                  <br />                        Interface: Power Charge Port                                                  <br />                        Audio Source: Electronic Products with 3.5mm Plug                                                  <br />                        Color: Black                                                	<br />Technical Parameters<br />	 Freq: 20Hz-20KHz                                                	<br />Other Parameters<br />	 Power Source: Wall Charger                                                	<br />Dimension and Weight<br />	 Product Weight: 0.403 kg                                                  <br />                        Package Weight: 0.905 kg                                                  <br />                        Product Size (L x W x H): 15.5 x 10.2 x 4.5 cm / 6.09 x 4.01 x 1.77 inches                                                  <br />                        Package Size (L x W x H): 26.5 x 18.5 x 6.5 cm / 10.41 x 7.27 x 2.55 inches                                                	<br />Package Contents<br />	 Package Contents: 1 x A915 320W Digital Power Loudspeaker Amplifier， 1 x US Plug Power Cable， 1 x Power Adapter， 1 x RCA Cable                                                	<br /><br /><br /><br />                                                                                            <br />
