| Bluetooth not connecting | Mixer not in BT mode, device not discoverable, out of range. | Ensure mixer is in 'BT' mode. Make sure your device's Bluetooth is on and discoverable. Move device closer to the mixer (within 33+ ft). |
| USB playback/recording not working | Unsupported file format, USB drive not detected, drive full, attempting simultaneous playback/recording. | Ensure files are MP3, WMA, APE, or FLAC. Check USB drive connection. Verify drive has sufficient space. Do not attempt playback and recording at the same time. |
| Distorted audio | Input gain too high, output level too high. | Reduce the GAIN knob for the affected channel. Lower the main output level. |
