4.2 Connecting to a Mobile Device (iOS/Android)

For mobile devices, an appropriate USB adapter is required (not included).

• สำหรับอุปกรณ์ iOS: Use an Apple Lightning to USB Camera Adapter (or a USB-C to USB-A adapter for newer iPads). Connect the adapter to your iOS device, then plug the Dragonfly Red into the adapter's USB-A port.
• สำหรับอุปกรณ์ Android: Use a USB-C to USB-A adapter (or Micro-USB to USB-A for older devices) with OTG (On-The-Go) functionality. Connect the adapter to your Android device, then plug the Dragonfly Red into the adapter's USB-A port.

Once connected, ensure your mobile device recognizes the Dragonfly Red as the audio output. Some Android devices may require a third-party music player app that supports USB audio output.

5. คู่มือการใช้งาน

The Dragonfly Red operates automatically once connected and recognized by your device. Simply play your desired audio content, and the Dragonfly Red will process the digital signal and output enhanced analog sound through its 3.5mm jack.

5.1 การควบคุมระดับเสียง

The Dragonfly Red features a 64-bit bit-perfect digital volume control. When connected to a computer or mobile device, the volume controls of your source device will directly adjust the output level of the Dragonfly Red. For optimal sound quality, it is recommended to set the source device's volume to maximum and then adjust the listening volume using the Dragonfly Red's internal volume control (which is linked to the source device's volume). This ensures the digital signal is passed to the DAC at its full resolution before attenuation.

6. Understanding the LED Indicator

The Dragonfly logo on the device illuminates in different colors to indicate the sampling rate of the audio being played:

• สีเขียว: 44.1 kHz (CD quality)
• สีฟ้า: 48กิโลเฮิรตซ์
• อำพัน: 88.2กิโลเฮิรตซ์
• สีม่วงแดง: 96 kHz (High-resolution audio)

This visual feedback allows you to confirm that your audio is being processed at the expected resolution.

7. การบำรุงรักษา

• Keep the Dragonfly Red clean by wiping it with a soft, dry cloth. Avoid using liquid cleaners or solvents.
• Store the device in its provided leatherette pouch when not in use to protect it from dust and scratches.
• หลีกเลี่ยงการให้อุปกรณ์สัมผัสกับอุณหภูมิ ความชื้น หรือแสงแดดโดยตรง
• Handle the USB connector and 3.5mm jack with care to prevent damage. Consider using a short USB extension cable (e.g., AudioQuest DragonTail) when connecting to laptops to reduce strain on the USB port and the device itself.

8 การแก้ไขปัญหา

8.1 ไม่มีเสียงออก

• Ensure the Dragonfly Red is securely plugged into the USB port of your source device.
• Verify that your headphones or audio system are correctly connected to the Dragonfly Red's 3.5mm output.
• Check your computer's or mobile device's sound settings to confirm that the Dragonfly Red is selected as the default audio output device.
• Increase the volume on both your source device and the connected headphones/audio system.
• Try restarting your computer or mobile device.
• If using a mobile device, ensure your adapter is compatible and supports OTG functionality. Some Android devices may require a specific music player app.

8.2 Intermittent Audio or Static

• Ensure all connections are firm and secure. Loose connections can cause audio interruptions.
• Test with different headphones or cables to rule out faulty accessories.
• If connected to a laptop, consider using a short USB extension cable to reduce physical strain on the USB port and potential interference.
• Minimize other USB devices connected to the same hub or computer, as power fluctuations can sometimes affect performance.
