The Behringer UCA222 is a compact USB audio interface that lets you connect analog audio gear (like mixers, keyboards, or other line-level sources) to your computer for recording and playback. It offers 2-in/2-out stereo audio via RCA jacks, a 3.5 mm headphone output with level control, and a TOSLINK optical S/PDIF digital output for digital connections. The interface uses 16-bit/48 kHz converters and is bus-powered via USB, so no separate power supply or drivers are needed — just plug it into a USB port and start recording in your DAW or editing software. It also comes with a bundle of audio software, including Audacity and other tools, to help you get started.
