How to use

Connect microphones or line-level devices to the appropriate channel inputs and adjust the individual channel level controls to achieve a balanced mix. Use the USB connection to route audio from a computer or to enable digital playback; select the USB input as a source if required by your playback device. Connect the mixer's main outputs to a PA system, powered speakers or a recording device, then set the master output level to match the input sensitivity of the downstream equipment. Make gradual gain adjustments to avoid clipping and check levels with headphones or monitoring speakers before live use.

Recommendations

For consistent performance, place the mixer on a stable surface and ensure cables are secured to prevent accidental disconnection. When using the USB audio feature with a computer, confirm the operating system recognizes the device and select it as the audio input/output in your audio software. Avoid extreme gain settings on individual channels to reduce distortion, and use a limiter or the PA system's protections when available for larger venues.
