Maintenance
- Cleaning: Use a soft, dry cloth to clean the mixer's surface. Avoid liquid cleaners or solvents.
- Ventilation: Ensure adequate airflow around the unit to prevent overheating. Do not block ventilation openings.
- Storage: Store the mixer in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Power Supply: Always use the original 18V AC external transformer provided with the unit.
Troubleshooting
- No Power: Ensure the power adapter is securely connected to both the mixer and a working power outlet. Verify the power switch is in the 'ON' position.
- No Sound Output: Check all cable connections to speakers and headphones. Verify main output levels and individual channel levels are appropriately set. Ensure the 2-track to mix switch is correctly engaged if using 2-track input.
- Hum or Noise: Check all audio cables for proper connection and integrity. Ensure proper grounding for all connected equipment. If using USB, some users have reported high-pitched noise or hiss, which may be related to computer grounding issues. Try connecting to a different USB port or a different computer, or consider using an external audio interface if the issue persists with USB.
- Distorted Sound: Reduce input gain levels on channels and the main output level. Check for clipping indicators (LEDs) and adjust accordingly.
- Effects Not Working: Ensure the effect section is enabled, an effect program is selected, and the Aux Send B and Effects/Aux Return B levels are adjusted.
