7. Q15 How to connect to mobile phone using USB mode?
Q15 can be used as a DAC for mobile phones. In UAC 2.0 mode, it can support 768K/DSD512. UAC 1.0 mode can support up to 96k.
Q15 has an independent mode selection switch, which can select "mobile phone mode" and "desktop mode".
Mobile phone mode: After Q15 receives the mobile phone and decodes it, you can choose whether to consume the mobile phone's power. When the switch is switched to the "ON" state, Q15 will not consume the phone's battery. When the switch is switched to "OFF" state, the mobile phone will charge the Q15.
Desktop mode: When the switch is switched to the "ON" state, the Q15 can be used as a desktop decoder. At this time, the power is greater, and the charger cannot charge the Q15 battery. When the switch is switched to the "OFF" state, the Q15 can be used as a desktop decoder. The mode will be released.
Note: To protect the battery, when the Q15 is shut down due to low battery, it will be forced to charge.
【Android phone】
Use the supplied TypeC-TypeC data cable to connect the Q15 to your mobile phone, play songs and enjoy high-quality music.
Troubleshooting possible exceptions:
If there is no sound after you connect, you need to pay attention to the following points:
-
Playback software settings, such as FiiO Music, if there is a USB output, you need to turn it on. Some devices have to turn off the USB output to have sound.
-
Confirm that USB debugging is turned on in developer mode
-
On the mobile phone, you need to open "Developer Options" in "Other Advanced Settings" and then turn on the "USB Debugging" or "OTG" function
-
Confirm that the adapter cable uses the officially distributed OTG double C cable. Whether the cable is connected reversely, there is a direction indicator.
-
After the above settings are completed, you can try to unplug and plug the data cable again, or play tracks and switch songs to rule out whether it is caused by hardware or software not recognizing it. If it still cannot be solved, it is recommended to contact our customer service to confirm whether it needs to be returned to the factory.
【iPhone】
Users who use Apple phones can purchase Fiio's Type C-Lightning data cable to connect the Q15 and Apple phones, and enjoy high-quality music by playing songs.
