To connect the FiiO KA2 Portable DAC Headphone Amplifier to your device, you can use a USB Type-C or Lightning cable to directly connect it to devices like a mobile phone or tablet PC. However, please note that there may be compatibility issues with some devices due to system and hardware differences. For some mobile phones, you may need to manually enable the OTG function in order to use the KA2 normally.
When connecting the KA2 to a PC running Windows 10.18.3 or above and Mac OS, it is driver-free. However, if you are using a PC running below Windows 10.18.3, you will need to download the USB DAC driver from the FiiO website (https://www.fiio.com/supports).
Please make sure to set the sound output to "KA2" or "K series" when playing audio on your computer.
