Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!!!Note:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!Please allow 1-2cm measuring deviation due to manual measurement.
