I purchased this solely to record narration on location, but I haven't used it since, so I'm putting it up for sale. I believe it's in excellent condition. I've confirmed that it works perfectly. As a bonus, I'm including a headphone jack adapter. *The power cable is not included, but it operates via USB bus power. This is a USB audio interface that achieves high-quality sound at 192kHz/24-bit. - Model Name: Rubix 24 - Inputs: 2-in - Outputs: 4-out - Sampling Rate: 192kHz - Bit Depth: 24-bit - Connection: USB - Phantom Power: 48V - Direct Monitoring: Supported - Output Terminals: TRS/XLR Thank you for looking.
