Note:

1. Why does the OLED screen display 'FSR ERROR' ?

When the output is invalid or unknown data, the device will display 'FSR ERROR'. This problem may be related to the player settings. Incorrect player settings or player bugs may cause the USB audio controller to receive information with non-normal sampling rate values, and the KA5 cannot output analog audio correctly. If this problem happens, please check whether the playback software or audio source works correctly.

2.Why does the OLED screen display 'BORN FOR MUSIC' ?

This is the standby mode of the KA5. When the KA5 is disconnected from the host's USB communication, the device will display 'BORN FOR MUSIC'. For example, when the device is not used for a long time while connected to a computer, or when the computer is in sleep mode, the KA5 will enter standby mode.
