Description: Using red ring output inductance, low output loss, more pure color All aluminum alloy body, gold-plated RCA and crystal speaker terminals, exquisite appearance Adopt high speed capacitance array, low internal resistance, dynamic swift and violent Plated RCA port output, Taiwan imported sealed potentiometer, heavy aluminum alloy heat dissipation Switch power supply, notebook computer switch power supply, battery or on-board power supply can be used. Specification: Material: Alloy Color: As picture show Size: Approx. 13x9.5x4cm/5.31x3.74x1.57inch Operating current: 8-25V Power: 0-50w (left + right) Power socket: DC 5.5 X 2.1mm Power supply voltage: 12V: 8?speaker /12W (left channel) + 12W (right channel) 4? speaker /20W (left track) + 20W (left channel) 15V: 8? /18 + 18W, 4? / greater than 30 + 30W 19V: 8? /32 + 32W, 4? / greater than 45 + 45W 24V: 8? /38 + 38W, 4? / greater than 55 + 55W Package Includes: 1 piece Power Amplifier Note: 1. Do not use without cheap audio signal line shielding, will introduce the high frequency noise, the greater the potentiometer to rotate followed by larger noise. 2. The order of use is: first, the notebook power and power amplifier interface is connected, and then let the notebook power on the city power. If you connect the laptop power to the mains, then plug the laptop plug into the digital amplifier, because the digital amplifier has a filter capacitor charging, which produces a slight low voltage spark for 0.1 seconds 3. The use of 19V power supply than the 12V power supply, low-frequency powerful, power is also large. (low quality difference between 19V and 12V)
