Gemini CDJ CDM-4000 CDJ (Dual CD Player). This is an all-in-one type with a built-in mixer. You can easily enjoy DJ play if you have CDs. The appearance is relatively clean, but the operation of the faders etc. is unstable, so I will sell it as a junk item! * Therefore, please purchase only if you understand. We do not accept any complaints after purchase. I think it's a great deal if you can repair it yourself! Thank you for your consideration!
