- Volume Control: Start with the master volume and individual channel volumes set to their lowest positions. Gradually increase the channel volume for the connected instrument until the desired level is reached. Adjust the master volume for overall output.
- Equalization (EQ): Use the 'Low' and 'High' knobs on each channel to adjust the bass and treble frequencies. Experiment with these controls to tailor the sound to your preference and instrument.
- Headphone Use: When headphones are connected, the main speaker output will be muted, allowing for private monitoring.

To clean the amplifier, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish and internal components. Ensure the amplifier is unplugged before cleaning.
Storage
When not in use for extended periods, store the amplifier in a cool, dry place, away from extreme temperatures and humidity. Covering the unit with a dust cover can help protect it from dust and debris.
