5.How to use the KA13 as a USB DAC for mobile phones?

【Android-based phone/PAD】

Use the TypeC-TypeC data cable to connect the KA13 to a mobile phone. So you can directly enjoy high-quality music by playing songs.

Notes:

1. A compatibility issue may occur to certain Android mobile phones or music players due to system and hardware differences.

2. Some mobile phones are required to turn on the OTG function, so as to use the KA13 normally.For detailed settings please consult the support of mobile phones.

3. Some mobile phones may show the 'non-certified Type-C digital headphone'notification. You can ignore the message and use it normally.

【iPhone/iPad】

Use the Lightning-TypeC OTG adapter to connect the KA13 to an iPhone/iPad/iPod. So you can directly enjoy high-quality music by playing songs.

Notes:

1.Only supports iOS10.0.2 and above. Apple devices below this version cannot be supported because of the iOS itself.

2.Since there are limitations for iPhone to power the external USB device, the KA13 with high output power may have stuttering or no sound problems at extreme volume.

About the Exclusive USB Audio Access Mode

Due to system and hardware differences of certain Android mobile phones, there may be some permission conflicts and compatibility issues when they are working in the Exclusive USB Audio Access Mode. Here are some situations we have noticed.

1.For some mobile phones with no physical volume buttons (such as the HUAWEI Mate30 Pro), in the FiiO Music app USB Audio Access Mode, you can adjust the volume by sliding on the current playback page to bring up the volume bar.

2.For some mobile phones, third-party apps are forbidden in the background by default in their power management policies. This will cause a stop on the playback after a few seconds when the music app is working in the Exclusive USB Audio Access Mode. If it happens, please set the app to stay working while asleep in the battery management setting of the mobile phone.

3.When the music app is working under the Exclusive USB Audio Access Mode, the sound may be stuttered or paused when operating other apps. We are working on this issue. It is suggested to focus on listening to music when using the Exclusive USB Audio Access Mode, or disable the Exclusive USB Audio Access Mode when listening to music.
