• Power Switch: Located on the left side of the front panel. Flip to turn the amplifier ON or OFF. A blue LED power indicator will illuminate when the unit is on.
• Treble Control: Adjusts the high-frequency output. Turn clockwise to increase treble, counter-clockwise to decrease.
• Bass Control: Adjusts the low-frequency output. Turn clockwise to increase bass, counter-clockwise to decrease.
• Tone / Direct Switch: This switch allows you to bypass the treble and bass controls. In "Tone" mode, the treble and bass knobs are active. In "Direct" mode, the audio signal passes through without tone enhancement, providing the original audio source sound.
• Volume Control: The large knob on the right adjusts the overall output volume. Turn clockwise to increase volume, counter-clockwise to decrease.

6. Maintenance

To ensure the longevity and optimal performance of your amplifier, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the amplifier. Avoid using liquid cleaners or abrasive materials.
• Ventilation: Ensure the amplifier is placed in a well-ventilated area to prevent overheating. Do not block the ventilation slots.
• Environment: Keep the amplifier away from direct sunlight, high temperatures, humidity, and dusty environments.
• Power Off: Always turn off the amplifier and disconnect it from the power source when not in use for extended periods or during electrical storms.

If you encounter issues with your amplifier, refer to the following common troubleshooting steps:

• No Power:
  • Ensure the power adapter is securely connected to both the amplifier and a working power outlet.
  • Verify the power switch on the amplifier is in the ON position.
  • Check if the power adapter is functioning correctly.
• No Sound:
  • Confirm that the audio source is playing and its volume is turned up.
  • Check all audio input and speaker output connections for secure and correct wiring.
  • Ensure the amplifier's volume knob is turned up.
  • Verify that the speakers are properly connected and functioning.
  • If using the Tone/Direct switch, try switching between modes.
