Steinberg UR22 USB Audio Interface A USB audio interface with high-quality 24-bit/192kHz audio and a D-PRE microphone preamplifier. Model: UR22 USB Standard: USB 2.0 Number of Inputs: 2 Number of Outputs: 2 Microphone Preamplifier: D-PRE Sampling Frequency: 192kHz Bit Depth: 24-bit Power Supply: USB bus power or external power ○ I mainly used this connected to my PC's monitor speakers, so I never really carried it around. Therefore, it's in near-mint condition with no noticeable scratches. However, if you are sensitive to minor signs of use or slight traces of wear and tear, please refrain from purchasing. I've used it for about two years, but I'm selling it because I'm upgrading to a different product. ○ Also, the sound works perfectly, and there are no functional issues. I never plugged or unplugged the XLR, MIDI, or headphone jacks, so they function like new. ○ The original box and instruction manual are not included. ○ The CD is included. ○ Please read my profile before purchasing.
