Hello, I just bought one of you power amplifier module. when I power it up only the 'clip' LED is on and the power LED is off. I did not connect the output to anything. The operating voltage was 40VDC. The power supply does not show any current being drawn. Need your help immediately. Thanks Venu@nus.edu.sg

Hi, Venugopalan. The typical operating voltage is DC52V. When the operating voltage is too low, clip will happen, which is normal. Please try to connect to a power supply with higher voltage. Could you please kindly connect the power amplifier to speakers to see whether there is output? If possible, please send a video or picture that could show your connection, to store@sure-electronics.com. We would solve it for you as soon as we receive the email.
