Setup Instructions

Follow these steps to set up your Jopwkuin D15 Digital to Analog Signal Converter:

1. Connect Digital Audio Source: Locate the digital audio output (Coaxial) on your source device (e.g., TV, set-top box, DVD player). Connect one end of the coaxial cable (not included, but typically comes with your source device or can be purchased separately) to this output and the other end to the "Input" coaxial port on the D15 converter.
2. Connect Analog Audio Output: Connect the 3.5mm audio jack from the D15 converter's integrated cable to the 3.5mm audio input on your receiving device (e.g., power amplifier, active speakers, headphones). If your receiving device uses RCA inputs, use the provided RCA connecting cable by plugging its 3.5mm end into the D15's 3.5mm output and the RCA ends into your device's L/R audio inputs.
3. Provide Power: Plug the USB connector from the D15 converter's integrated cable into a standard USB power source (e.g., a USB port on your TV, a USB wall adapter, or a computer USB port). The converter requires 5V DC power.
4. Power On Devices: Ensure both your digital audio source and your analog audio receiving device are powered on.

Operating Instructions

The Jopwkuin D15 converter operates on a simple plug-and-play principle. Once all connections are made and devices are powered on, the converter will automatically process the digital audio signal.

• Signal Conversion: The converter will automatically detect the incoming digital coaxial signal and convert it to an analog audio signal.
• Audio Output: The converted analog audio will be output through the 3.5mm jack. Ensure your connected audio device (amplifier, speakers, headphones) is set to the correct input source and its volume is adjusted appropriately.
• Indicator Light: The converter may feature a small indicator light (as shown in product images) that illuminates when power is supplied and the device is operational.

Maintenance

The Jopwkuin D15 Digital to Analog Signal Converter requires minimal maintenance to ensure its longevity and optimal performance.

• Cleaning: Use a soft, dry cloth to wipe the surface of the converter. Do not use liquid cleaners or abrasive materials, as they may damage the device.
• Storage: When not in use for extended periods, store the converter in a cool, dry place away from direct sunlight and extreme temperatures.
• Cable Care: Avoid sharp bends or kinks in the integrated cables to prevent internal wire damage. Do not pull on the cables to disconnect the device; always grasp the connector itself.
