I purchased this new around the summer of 2025 and used it about once every two weeks. I am selling it because I am changing models. There are no problems with its use, but there are some scratches near the input jack. They are only visible when held up to the light, so please refrain from purchasing if you are concerned about this. I will ship it with the original box. 【Audio-Technica / AT-UMX3】 【Product Overview】 A USB audio mixer for live streaming, created by a microphone manufacturer. 【Product Description】 ■ Design technology and sound quality evaluation unique to a microphone manufacturer ■ Enhanced noise resistance through dedicated design ■ Uses a high-performance A/D converter with a maximum of 192kHz/24bit ■ Can supply stable 48V phantom power ■ Neutrik XLR/φ6.3mm combo jack is used for the microphone terminal ■ Hi-Z input terminal allows direct connection of electric guitars, etc. ■ Plug and play with PC, smartphone, and tablet for immediate use (※Accessories not included) ■ Independent microphone, LINE input, and USB input, with an easy-to-understand control panel ■ Compatible with major streaming platforms ■ Direct monitor allows you to monitor your voice and performance with zero latency ■ LOOPBACK function convenient for mixing in live streaming ■ Microphone mute function to instantly mute unwanted sounds and focus on the sounds you want to stream ■ Microphone monitor mute function to adjust the sound being monitored ■ Terminals are concentrated on the back, combining a compact size with stability 【Product Specifications】 ■ External dimensions (including protrusions): H44 x W127 x D131mm ■ Weight: 334g
