Multi-functional USB mixer with a compact design that supports low-noise microphones. - Model Name: Musical Mini Mixer - Function: Multi-function PC Interface Mixing Console - Connection Type: USB connection - Microphone Input: For low-noise dynamic microphones - Size: Compact size Thank you for viewing. I opened it once after purchase and connected it for streaming, but I am selling it because I am switching to another mixer. I think it is very high-performance for first-time users.
