【High-Quality Audio】 The Fireface UC is an audio interface that provides professional sound quality, perfect for music production and recording. I previously purchased it used on Mercari and have confirmed that it powers on. The sound was also quite clear, but it didn't quite fit my music setup. I decided to sell it because I found a simpler interface that suited me better, and it hasn't been long since I purchased this one. The box was not included from the previous owner. *Everything is shown in the photos. Also, I have never used the software mixer, and I was simply connecting it and getting sound. 【Various Connection Options】 Equipped with XLR/TRS combo jacks, you can easily connect microphones and instruments. USB 2.0 connection provides excellent compatibility with PCs. 【Included Accessories】 An AC adapter and USB cable are included, so you can start using it right away. - Model: Fireface UC - Connection Terminals: XLR/TRS combo jacks - USB Port: USB 2.0 - Power Adapter: Non-genuine - USB Cable: Non-genuine Thank you for viewing.
