Power connections

The MAX9744 amplifier can use between 5-14VDC power. The higher the voltage, the more gain you can get. So if you

want 20W per channel, you'll need to supply 12VDC. The amplifier is a Class D - so it only draws current when its

playing audio, but the voltage requirement is still pretty important. If you pick a voltage too low, you'll hear distortion on

the speakers because the output is 'clipping'
