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. Mode d'emploi

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 Contrôle du volume

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:

• Vert: 44.1 kHz (CD quality)
• Bleu: 48 kHz
• Ambre: 88.2 kHz
• Magenta: 96 kHz (High-resolution audio)
