Thank you for viewing. This is the audio-technica AT-UMX3 USB audio mixer. It features a loopback function and can be used for streaming, game commentary, and more. The simple design allows for intuitive operation. It works especially well with condenser microphones like the AT20 series, providing excellent sound quality. I purchased this in February of this year. It's in beautiful condition with little use. The original USB cable is included. I will not be responding to price negotiations. Thank you for your understanding.
