This 12-channel analog mixer features built-in effects and a mute function on each channel. I have used it daily for two years. The MUTE switch feels a bit unstable and the fader on channel 9 is a little shaky, but it generally works without any problems. You can also use the USB connection as an audio interface for the main LR output. - Number of channels: 12 channels - Effect engine: Built-in effects - Main output: Main output terminals - Microphone input: XLR microphone input - Sliders: Sliders on each channel - Mute function: Mute buttons on each channel - AUX output: AUX output terminals - Pan control: Pan knobs on each channel Thank you for looking.
