4. Setup Instructions

4.1. Power Supply Connection

1. Ensure the amplifier board is powered off.
2. Connect a DC power supply (5-24V) to the "DC 5-24V" input terminals on the board. Observe polarity: connect the positive (+) terminal of the power supply to the "+" terminal on the board, and the negative (-) terminal to the "-" terminal.
3. A 12V-24V power supply with sufficient current (e.g., 5A or higher for 100W output) is recommended for optimal performance.

4.2. Speaker Connection

1. Connect your passive speakers to the "AUDIO OUTPUT" terminals.
2. Connect the left speaker to the "L+" and "L-" terminals.
3. Connect the right speaker to the "R+" and "R-" terminals.
4. Ensure correct polarity for each speaker to avoid phase issues.

4.3. Audio Input Selection

The XY-C100L supports three audio input methods: Bluetooth, AUX (3.5mm jack), and USB Audio.

• Bluetooth: For wireless audio streaming.
• AUX IN: Connect an external audio source (e.g., smartphone, MP3 player) using a 3.5mm audio cable.
• USB AUDIO: Connect to a computer via a USB cable for digital audio input.

The amplifier automatically detects and switches to the active input source. If multiple sources are connected, Bluetooth usually takes priority. You may need to disconnect other sources or pause playback to switch.

5. Operating Instructions

5.1. Powering On/Off

Once the power supply is connected, the board will power on automatically. To power off, disconnect the DC power supply.

5.2. Bluetooth Pairing

1. Ensure the amplifier board is powered on.
2. On your Bluetooth-enabled device (e.g., smartphone), search for available Bluetooth devices.
3. Select "XY-C100L" from the list of devices to pair.
4. Once paired, a confirmation sound may be heard, and you can now stream audio wirelessly.

5.3. Volume Control

The large rotary knob on the board controls the master volume. Rotate clockwise to increase volume and counter-clockwise to decrease volume. The knob offers stepless tuning for precise adjustment.

5.4. Playback Control (Bluetooth/USB)

For Bluetooth and USB audio inputs, playback control (play/pause, next/previous track) is typically managed directly from your connected source device.

7. Maintenance

• Keep the amplifier board clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid placing the board in environments with excessive heat, humidity, or direct sunlight.
• Do not attempt to disassemble or modify the board, as this will void any potential warranty and may cause damage.

8. Troubleshooting

No Power:

• Check if the DC power supply is correctly connected and providing the specified voltage (5-24V).
• Ensure the power supply is functional.
• Verify correct polarity of the power connection.

No Sound Output:

• Confirm speakers are correctly connected to the "AUDIO OUTPUT" terminals with correct polarity.
• Check the volume level on both the amplifier board and the source device.
• Ensure the correct audio input source is active (Bluetooth, AUX, or USB). Try disconnecting other sources.
• Test with a different audio source or speakers to isolate the problem.

Bluetooth Pairing Issues:

• Make sure the amplifier board is powered on and within range of your Bluetooth device.
• Ensure no other device is currently paired with the amplifier. Disconnect from other devices if necessary.
• Try restarting both the amplifier and your Bluetooth device.
• Clear previous Bluetooth connections on your device and try pairing again.

Distorted Sound:

• Reduce the volume on both the amplifier and the source device.
• Ensure the power supply is adequate for the output power (e.g., higher current for higher volume).
• Check speaker impedance compatibility.
• Inspect audio cables for damage or loose connections.
