12-channel analog mixer with built-in effects. Purchased two years ago and only used a few times for live performances. Selling because the specifications are more than I need and it takes up too much space. Everything in the photos is included. I'm also including a pair of Audio-Technica headphones, which are not originally included. - Model Name: ProFX12v3 - Number of Channels: 12 channels - Effects: Built-in effects - Connectors: XLR/TRS combo jacks - Power: AC power Thank you for looking. Please search online for the detailed specifications.
