- Channel EQ: Use the HIGH, MID, and LOW knobs on each channel to adjust the tonal balance of individual inputs.
- Channel Volume: Use the channel faders to control the volume of each input in the main mix.
- Pan Control: Adjust the PAN knob to position the sound of each channel in the stereo field (left to right).
- Main Mix: Use the MAIN MIX faders to control the overall output volume.
- Mute Function: Each channel features a one-click mute button to quickly silence an input. An indicator light shows the mute status.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Power off; cables disconnected; volume down; muted channel | Check power, connections, main mix faders, channel faders, and mute buttons. |
| Distorted sound | Input gain too high; output level too high; faulty cable | Reduce GAIN on input channels. Lower MAIN MIX faders. Check and replace cables if necessary. |
| Microphone not working | Incorrect input; +48V phantom power off (for condenser mics); faulty mic/cable | Ensure mic is connected to correct input. Activate +48V for condenser mics. Test with another mic or cable. |
| Bluetooth not connecting | Mixer not in pairing mode; device too far; interference | Ensure mixer is in Bluetooth mode. Keep device close. Restart both devices. |
| No DSP effects | Effect send/return knobs low; effect not selected | Increase FX/AUX send on channels. Adjust EFFECT RETURN. Select an effect. |
