Connections
Follow these steps to correctly connect your amplifier:
- Speaker Connection: Connect your passive speakers to the output terminals on the amplifier. Ensure correct polarity: connect the red terminal to the speaker's positive (+) terminal and the black terminal to the speaker's negative (-) terminal.
- Audio Source: Your audio source (e.g., smartphone, tablet, computer) will connect wirelessly via Bluetooth. No physical audio input cables are required.
- Power Supply: Connect a DC power supply (5-24V) to the DC input jack on the amplifier. Ensure the power supply is suitable for the amplifier's requirements.
Operating Instructions
Power On/Off
Once all connections are securely made and the power supply is connected, the amplifier will automatically power on. To turn off the device, simply disconnect the DC power supply.
Volume Control
The large knob located on the top surface of the amplifier controls the output volume. Rotate the knob clockwise to increase the volume and counter-clockwise to decrease it.
Bluetooth Pairing
To connect your audio source via Bluetooth:
- Ensure the XY-KA50H amplifier is powered on.
- On your audio source device (e.g., smartphone, tablet), navigate to the Bluetooth settings and enable Bluetooth.
- Search for available devices. The amplifier should appear as "XY-KA50H" in the list.
- Select "XY-KA50H" to initiate the pairing process. A confirmation sound may indicate successful pairing.
Maintenance
- Cleaning: Use a soft, dry, and lint-free cloth to clean the exterior of the amplifier. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the finish or internal components.
- Storage: When not in use for extended periods, store the amplifier in a cool, dry place, away from direct sunlight, dust, and extreme temperatures.
Troubleshooting
- No Sound Output:
- Verify all speaker and power cable connections are secure and correct.
- Ensure the volume knob on the amplifier is not set to minimum.
- Confirm that your audio source device is playing audio and is successfully paired via Bluetooth.
- Check that the power supply is providing the correct voltage (5-24V DC) and is properly connected.
- Distorted Sound:
- Reduce the volume on both the amplifier and your audio source device. Overdriving the amplifier or speakers can cause distortion.
- Ensure your speakers have an impedance within the recommended 4-8Ω range.
- Inspect speaker wires for any damage or short circuits.
- Bluetooth Disconnection or Pairing Issues:
- Ensure the amplifier and your audio source device are within close proximity (typically within 10 meters) and there are no significant obstructions.
- Try unpairing and then re-pairing the device from your audio source's Bluetooth settings.
- Check for potential interference from other wireless devices operating on the same frequency.
