Product Description FAQ

1. How to control the KA5 via the FiiO Control APP on an Android mobile?

To control the KA5 via the FiiO Control APP on an Android mobile, connect the KA5 to the Android mobile phone using the USB C to C adapter provided with the KA5.

Note: The KA5 cannot be controlled via the iOS version of the FiiO Control APP. However, after adjusting the settings either on the KA5 or within the Android FiiO Control APP, the settings will be saved.

When adjusting settings via the FiiO Control APP for KA5, the settings on the device display change immediately. However, if you adjust the settings directly on the KA5, the menu in the FiiO Control APP does not change. This design ensures that only some settings change synchronously to avoid audio stuttering and other issues that may occur if all settings were designed to change simultaneously.

1. Why does the screen freeze on the FiiO logo when I turn on the device?

If the screen freezes on the FiiO logo when you turn on the device, it may be because the volume-down button was accidentally pressed before connecting to the USB port, causing the device to enter burning mode. To resolve this issue, unplug the device and restart the KA5.

1. When using coaxial output, is the volume adjustable on the front device?

Yes, when the KA5 is set to coaxial output, both the front and rear ends can adjust the volume.

1. How to use SPDIF output in KA5?

To use the SPDIF function, enable the SPDIF switch in the menu first. Then, connect the KA5 to the coaxial input port of another device using a dedicated 3.5mm to RCA coaxial cable. The pin definition diagram is as follows: L-R-GND-SPDIF OUT.

1. How do I enter UAC1.0 mode on KA5?

The UAC 1.0 mode on KA5 supports Win7, Win8, PS5, etc. To enter UAC1.0 mode, disconnect and turn off the KA5. Then, while holding the multifunction button, connect it to a UAC1.0 device.
