Used only once for recording and worked without any problems. I'm selling it because I don't have a chance to use it. Includes accessories such as the adapter. The bag containing the manual has not been opened, so the included Cubase LE is also unused. - Model: US-4x4HR - Inputs: 4 - Outputs: 4 - Connection Type: USB - Included Software: Cubase LE - Accessories: Manual 4-input, 4-output USB audio interface, Cubase LE included. - Brand: TASCAM - Model: US-4x4HR - Connection Type: USB - Inputs: 4 - Outputs: 4 - Mic Inputs: XLR - Line Outputs: TRS - Accessories: Power adapter, USB cable - Software: Cubase LE Thank you for viewing.
