I purchased this on Mercari, but it was not compatible with my device, so I am selling it. The following is a quote from the buyer's description: >>> 【Extremely durable! Equipped with a loopback function, it can be used for streaming and meetings!】 Used indoors for about 6 months. Operation has been confirmed. It has not been used in a smoking environment. There are some scratches on the surface, but there are no problems with the operation. *Box not included. Please refrain from purchasing if you are sensitive to used items. I am selling it due to downsizing for moving. It's easy to use! It's durable, so it's also recommended for taking to outdoor locations!! 【Included】 USB cable 【Main Features】 24-bit/192kHz USB 2.0 audio interface D-PRE microphone preamps x2 (phantom power +48V compatible) XLR/TRS combo input x2 (INPUT 2 has Hi-Z switch), 1/4” TRS phone output x2 CC mode (requires a separate Camera Connection Kit / Lightning USB camera adapter) / USB bus power (requires a separate 5V DC adapter or battery pack when connected to an iPad) MIDI input/output Headphone jack (with independent volume control) Near-zero latency monitoring with Mix balance control Loopback function Robust all-metal body The UR22mkII is an audio interface that further evolves the best-selling model UR22, which has become a standard.
