I was using this connected to a PC via USB to play electronic drums and guitar. The exterior has some scratches and shows signs of use. Please check the photos for the included accessories. I will wrap the original box in bubble wrap for shipping. An 8-input analog mixer with a USB audio interface. It features 3-band EQ and one-knob compressor on all input channels, achieving high-quality mixing. Features 6-channel configuration with 2 mono and 2 stereo inputs, plus 2 AUX and 2 track inputs.
