<br />
<br />Power supply: DC 9-15V/50-100W
<br />
<br />Channel type: 2.0 stereo
<br />
<br />Response frequency: 20Hz-20KHz
<br />
<br />Matching speakers: 4-8  20-120W 3''-10'' bookshelf speaker, floor speaker
<br />
<br />Instructions:
<br />
<br />1. Connect to speakers
<br />
<br />Connect the two wires of the speakers to the audio output port of the power amplifier, the left channel speaker is connected to the LOUT port of the amplifier
<br />
<br />and the right channel speaker is connected to the ROUT port, the positive connects to "+",the negative connects to "-".
<br />
<br />2. Connect to sound source
<br />
<br />Use an audio cable with a end of 3.5mm stereo headphone plug and plug in 3.5 stereo headphone jack of the amplifier.
<br />
<br />The other end of the audio cable is connected to the audio source (such as computers, mobile phones, MP3, DVD).
<br />
<br />3. Connecting to power supply
<br />
<br />1)Connect to the adapter of power supply
<br />
<br />Use the power supply which the output is above DC12V3A.
<br />
<br />Connect the output cable of the adapter to the 12V port of the power amplifier board.
<br />
<br />The positive connects to "+" of the port while the negative connects to "-".
<br />
<br />2)Connect voltage converter
<br />
<br />Use the voltage converter which the output is above AC12V3A.
<br />
<br />Connect the two output cables of the converter to the 12V port of the power amplifier board.
<br />
<br />Because the output of the converter is alternating current, it is not positive or negative.
<br />
<br />4. Play music
<br />
<br />Plug in the power, the blue power indicator will light up which means that the power amplifier board start working.
