【Condition of Item】 I opened the item, but it didn't connect properly, so I barely used it and it's been sitting in storage. I am now selling it. I have confirmed that it works, and there are no noticeable scratches. 【Included Items】 There is no box, only the main unit and the power adapter. 【Product Description】 This is a mixer with 5 stereo inputs, allowing up to 10 input devices to be connected simultaneously. It has gain control, supporting both line and microphone levels. Without affecting the overall mixing output, you can freely adjust whose voices you want to hear and whose you don't on your own loop mixer. It also easily facilitates training with multiple people and supports serial connections of multiple sound source groups.
