• RCA Input: Use the RCA to 3.5mm cable to connect to devices with RCA outputs (e.g., turntables, CD players) or a 3.5mm output (e.g., computers, smartphones).
• TRS Input: For balanced audio connections from professional audio equipment like mixers or audio interfaces, use 1/4-inch TRS cables.
• AUX Input: A front-panel 3.5mm AUX input is available for quick connection of portable devices.

4. Power Connection

Connect the power cable to the active speaker and then to a wall outlet. The power indicator on the front of the active speaker will illuminate.

4. Headphone Output

Maintenance

Cleaning

Wipe the speaker cabinets with a soft, dry cloth. Do not use liquid cleaners or aerosol sprays. Avoid placing objects on top of the speakers that could block the rear port or damage the drivers.

Storage

If storing the speakers for an extended period, disconnect them from power and store them in a cool, dry place, preferably in their original packaging to protect them from dust and physical damage.

Troubleshooting

No Sound

• Ensure the speakers are powered on and the LED indicator is lit.
• Check all cable connections (power, speaker-to-speaker, audio input) are secure.
• Verify the volume is not set to minimum on both the speakers and your audio source.
• Confirm the correct input source is selected (e.g., RCA, TRS, AUX).
• If using headphones, ensure they are unplugged from the front jack.

Distorted Sound

• Reduce the volume on both the speakers and your audio source.
• Check if the audio source is producing a clean signal. Try a different source.
• Adjust the Low/Bass and High/Treble controls on the rear panel.

Humming or Buzzing Noise

• Ensure all cables are properly shielded and away from power cables.
• Try plugging the speakers into a different power outlet.
• Disconnect all audio input cables to determine if the noise originates from the source device.
