How to use

Connect microphones and line-level sources to the appropriate input channels, set gain and trim to achieve a clean input level, then use the channel faders to blend sources into the main mix. Adjust per-channel EQ to remove unwanted frequencies or to enhance clarity. Use the USB audio interface to route the stereo mix to a computer for recording or streaming, and configure the computer’s audio settings to recognize the mixer as the input/output device. Monitor the output via headphones or powered monitors and adjust master level and monitor sends as required.

Recommendations

For reliable operation, perform a soundcheck before each event to confirm input levels, EQ settings and USB connectivity. Use balanced cables where possible to reduce noise, and keep firmware or driver software (if provided) up to date on the connected computer for best USB performance.
