Power socket: DC 5.5 X 2.1mmPower supply voltage:
12V: 8Ωspeaker /12W (left channel) + 12W (right channel)
4Ω speaker /20W (left track) + 20W (left channel)
15V: 8Ω /18 + 18W, 4Ω / greater than 30 + 30W
19V: 8Ω /32 + 32W, 4Ω / greater than 45 + 45W
24V: 8Ω /38 + 38W, 4Ω / greater than 55 + 55WPackage Includes:1 piece Power AmplifierNote:1. Do not use without 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)Power Amplifier;Stereo Power Amplifier;Digital Audio Amplier;Dual Channel Amp;HIFI Power Amp;8-25V 50W x2
