RME USB FireWire Audio Interface Fireface UCX I purchased this from Soundhouse during the COVID-19 pandemic. Shortly after the purchase, the pandemic began to subside and work started, so it is in near-new condition. It has been used only once or twice, so it is in a condition close to new. Currently, the latest model, Fireface UCX II, is experiencing a price increase and is difficult to obtain. Some people choose this original UCX as an alternative, and in fact, it still has specifications that allow it to be used at the forefront. Of course, it works without any problems on the latest Mac/Windows OS. Personally, I feel that it can monitor with the same sound quality as the current BabyFace Pro FS, and rather, considering the number of channels, I think the UCX has an advantage in a desktop environment. ・Accessories Main unit, outer box, power cable and adapter USB B to A cable MIDI cable Two Japanese user guides (DigiCheck and the main unit's user guide) ※Everything in the photos is included. ・Condition Used and stored in a non-smoking environment. Since it has only been used once or twice, it is in a condition close to new. The box has scratches and creases. ※Please check the photos. ・Operation I have not felt any particular problems so far. I have confirmed that the connection with Totalmix FX, EQ, and dynamics works without any problems. Also, I have confirmed that the headphone output and other analog in/out channels connect and operate without any problems, but because it is a very multifunctional audio interface, I have not been able to confirm all operations, so please understand this in advance. Returns and exchanges are not accepted to prevent swapping. Thank you for your understanding.
