How to use

Connect sources to the available input channels and set initial trim/gain and channel-level controls to unity. Use the USB input to play digital audio from a connected computer or USB device, and adjust the corresponding channel level for integration with other sources. Select the desired channel(s) for cueing to the headphone output to prepare transitions and checks before releasing audio to the main mix. Use the master output control to set the overall sound level for the PA or recording device.

Recommendations

For reliable operation, allow the mixer and connected devices to warm up briefly before performing and keep channel levels below clipping by monitoring peak indicators if available. Use the cue function to check source levels and EQ balance prior to sending signals to the main output. When recording, verify USB playback levels and routing to ensure clean signal capture.
