Description: This is the Behringer EURORACK MX602A, a compact analog mixer. Despite its small size, it's very user-friendly and can be widely used for sub-mixing, DTM, streaming, and more. [Condition] Sound output from each channel has been confirmed. I used it normally, connecting it to an amplifier and then to BOSE 101 speakers. There are no missing knobs, and it's in relatively good condition for its age. There may be some crackling, but it usually resolves after turning the knobs a few times. [Included Items] Original AC adapter (rare 3-pin type) [Shipping] It will be carefully packed with bubble wrap and shipped via Rakuraku Mercari delivery. To prevent any issues after purchase, please feel free to ask any questions, no matter how small. Thank you for your understanding regarding used items!
