Make sure you use a 3.5mm plug to RCA split cable as shown in the pictures. There is one version of the Lepai amp that has the 3.5mm input jack connections inside on the circuit board reversed to what it should be. If you use a straight 3.5mm cable from Airplay to amp the output speakers will be on the opposite channel. If you open the amp and the circuit board is red in color you probably got one that is wrong. You can read about it here:
