TASCAM US-322 Audio Interface High-quality USB 2.0 audio interface. Features two microphone inputs, headphone output, and a monitor mix function for intuitive operation. Suitable for both streaming and DTM (Desktop Music) applications. It used to work without problems, but I haven't been able to install the drivers on the latest Windows/Mac systems, so the recent input/output functionality is unconfirmed. Therefore, it is being sold as junk. Accessories include only the USB cable as shown in the photos. There is no box, included CD, or instruction manual, but the drivers and manual can be downloaded here: https://tascam.jp/jp/product/us-322/download Supported OS: Windows Windows 10 (May 2019 Update), Windows 8.1, Windows 8, Windows 7, Windows XP Mac macOS Mojave, macOS High Sierra (10.13), macOS Sierra (10.12), OS X El Capitan (10.11), OS X Yosemite (10.10), OS X Mavericks (10.9), OS X Mountain Lion (10.8), OS X Lion (10.7), Mac OS X Snow Leopard (10.6) Instruction Manual: https://tascam.jp/downloads/products/tascam/us-322_us-366/J_US-322_366_OM_vC.pdf Used in a smoke-free and pet-free environment.
