12-channel analog mixer with USB support. 12-channel analog mixer with 24 built-in effects. Unfortunately, I am selling it to organize my equipment. I was using it until recently, so it works perfectly. The AV adapter included with this product is model PA-10, which is subject to recall, but the date code is 1927, so it is not a recalled item, so please rest assured. - Brand: YAMAHA - Model Name: MG12XUK - Number of Input Channels: 12 - USB Connection: Yes - Effects: 24 built-in effects - Power Adapter: Included - Level Adjustment Knobs: Available on each channel - Monitoring Function: Monitor headphone output available Thank you for viewing. - Model Name: MG12XUK - Number of Channels: 12 - USB Connection: Supported - Number of Effects: 16 - Peak Indicator: Equipped - Level Adjustment: Independent for each channel - Monitoring Function: Equipped - EQ Band: 3-band (high, mid, low) Thank you for viewing.
