This is an 8-channel auto lighting control system. It can perform functions such as power ON/OFF, sound activation (sound reaction), and automatic flashing. I lost the AC adapter during a move, but both devices were still able to be powered on (about half a year ago). The device with the power cable attached is still confirmed to be powered on, but please consider it as a junk item for parts, just in case. There is a distortion in the ear part of the device, but there were no problems with implementation. ■ 8ch Auto Lighting Control System ■ Supports up to 1500W ■ Equipped with 8ch on/off switches ■ Equipped with a full-on switch ■ Chase speed adjustable ■ Sound active compatible ■ Controller = Power pack cable (5m) included ■ Power adapter: DC9V0.5A included ■ Dimensions/Weight: Controller: 48W x 4.4H x 6Dcm, 1U, 1kg Power pack: 48W x 10H x 10Dcm, 2kg
