I am selling this item because I recently purchased it last month but no longer need it as I acquired a different model. It has been used for a short time and is in good condition. Of course, it works without any problems. Regarding the included DAW, Cubase AI: I have only used the activation code, and I have applied to Steinberg to transfer the license, removing my registration. I have received a new activation code (see image 7), so you can use it as normal by registering it. Supported sampling rate: Up to 192kHz AD/DA: 24bit Connection: USB 2.0 Type-C Inputs: 1 microphone input (XLR/TRS combo), 1 line input (Hi-Z compatible) Outputs: TRS output x 2, headphone output (shared with output volume) Features: Loopback function, direct monitoring Power: USB bus power (5V DC, 0.5A) Supported OS: Windows, macOS, iOS, Android Thank you for viewing.
