This is a brand new AL8X frame (AL80B, AL800, AL800H, AL572) 16-pin jumper cable 18 inches long. This jumper connects the power supply board to the metering board. Be very careful routing and inserting male plug ends. The pins are fragile and can only be straightened a few times before they break. Do not bend or misalign pins when inserting and removing this cable! Do not pinch this cable with the amplifier cover! We test and warranty our assembly but cannot warranty user electrical or physical damage.
