5.2 Step-by-Step Connection

1. Power Connection: Connect the provided DC 12V-18V power adapter to the 'DC Voltage Input' port on the rear panel. Plug the adapter into a suitable power outlet (AC 100~240V compatible).
2. Speaker Connection:
   • Connect your passive speakers to the 'Speaker Outputs' terminals (A/B and C/D) on the rear panel. Ensure correct polarity (+ to + and - to -) for each speaker. The amplifier supports speakers with an impedance of 2-8Ω.
   • Important Note: The bass speaker (subwoofer) requires an active subwoofer connected to the 'SUB-WOOFER OUT' port. Passive subwoofers are not directly supported by this output.
3. Audio Input Connection: Choose one of the following methods:
   • Coaxial Input: For high-quality digital audio, connect a coaxial cable from your CD/DVD player, TV, or other compatible device to the 'Coaxial Input Terminal'.
   • RCA Audio Input: Use RCA cables to connect analog audio sources like computers, mobile phones, or other audio players to the 'Left and Right Channel Input'.
   • Bluetooth Connection: Ensure the Bluetooth antenna is connected. Switch the amplifier to Bluetooth mode. On your device, search for 'LEPY LP-269PRO' and pair.
   • USB/SD Card Playback: Insert a USB flash drive into the 'USB Socket' or an SD/MMC card into the 'SD Socket'. The amplifier will automatically detect and play supported audio files (WAV, APE, FLAC).
4. FM Antenna Connection: Connect the included FM antenna to the 'FM Antenna Port' on the rear panel for optimal radio reception.

7. Troubleshooting

• No Power: Ensure the power adapter is securely connected to both the amplifier and a working power outlet. Check if the power outlet is active.
• No Sound:
  • Verify that the amplifier is powered on and the volume is turned up.
  • Check all speaker connections for proper polarity and secure fit.
  • Ensure the correct input source is selected (e.g., Bluetooth, USB, Coaxial).
  • If using an active subwoofer, ensure it is powered on and connected correctly to the 'SUB-WOOFER OUT' port.
• Bluetooth Connection Issues:
  • Make sure the amplifier is in Bluetooth mode ('BLUE' displayed).
  • Ensure your device's Bluetooth is enabled and it is within range.
  • Try unpairing and re-pairing the device.
  • Ensure no other devices are currently connected to the amplifier via Bluetooth.
• USB/SD Card Not Playing:
  • Ensure the USB drive or SD card is inserted correctly and fully.
  • Check that the amplifier is in the correct USB or SD mode.
  • Verify that the audio files on the drive/card are in a supported format (WAV, APE, FLAC).
  • Try a different USB drive or SD card to rule out media issues.
• Poor FM Radio Reception:
  • Ensure the FM antenna is securely connected.
  • Adjust the position and orientation of the FM antenna for better signal reception.
  • Perform an auto-scan (SCN button on remote) to find available stations.
• Distorted Sound:
  • Reduce the volume level.
  • Check speaker connections for loose wires or incorrect polarity.
  • Ensure the audio source is not overdriving the input.

8. User Tips

• Active Subwoofer Required: Remember that the 'SUB-WOOFER OUT' port requires an active (powered) subwoofer. A passive subwoofer will not produce sound when connected to this output.
• Speaker Impedance: For optimal performance and to prevent damage, ensure your passive speakers have an impedance between 2Ω and 8Ω.
• Power Compatibility: The included power adapter supports AC 100-240V input, making it compatible with various regional power standards (e.g., 110V in US, 220V in Chile).
• Speaker Polarity: Always connect speaker wires with correct polarity (+ to + and - to -) to ensure proper sound reproduction and prevent phase issues.
• Cable Quality: Using good quality audio cables can help minimize interference and improve sound clarity.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the amplifier's exterior. Avoid using liquid cleaners, aerosols, or abrasive materials, as they may damage the finish or internal components.
• Placement: Place the amplifier on a stable, flat surface with adequate ventilation to prevent overheating. Avoid direct sunlight, heat sources, and areas with high humidity or dust.
• Power Disconnection: If the amplifier will not be used for an extended period, unplug the power adapter from the wall outlet.
