KA1 V1.21 Firmware Changes and improvements about new firmware are as follows :

1. Added support for FiiO Control App;

2. Added support for in-line control microphones;

3. Added the setting of turning on/off indicator light;

4. Added the function of USB mode switching.


Note:

1. FiiO Control App iOS version does not support the control for KA1.

2. In-line microphone function could be enabled via FiiO Control app. (The function

   will be set after reconnect).

   Some mobile phones(Like Hwawei, iPhone) do not support calling via microphone

   in the headphone of KA1.

   When in-line microphone function is on,  DSD native mode would work only when

   using headphone without microphone.

3. USB 1.0 and USB 2.0 mode could be switched via FiiO Control App. (The function

   will be set after reconnect.)

   USB2.0 is set as default. When using with device like switch, you could switch to

   USB 1.0 mode first.
