2. What should I do if the K19 is abnormal? And safety instructions

No sound, noisy sound, no power on

The following methods can help you troubleshoot the cause:

1. Check whether the AC/DC toggle switch matches the currently plugged in power supply. Unplug and replug the power cord, and turn on the switch on the back of the K19. It does not support the reset function, so we need to turn the back switch off, and then turn it on again to reboot the K19.

2.Check whether the usage mode, input and connection are correct.

3. Replace the input terminal: Switch to other input ports, or change to a mobile phone or computer under USB to locate whether the fault is from the K19 or the front end.

4. Replace the output terminal: such as earphones, earphone cables, replace them with other outputs such as line output, balanced output, etc. to locate the fault.

When connecting to the front panel headphone ports, the output selection needs to be switched to [PO] or [PO+PRE]. When connecting to the rear panel output ports, the output selection needs to be switched to [PRE] or [LO] or [PO+PRE].

5. Software side: There are many reasons for the software side failure, which can be eliminated by the following methods, whether the DAC driver is installed, whether the playback software and the output of the system are correspondingly switched to K19, and whether other sampling rate Flac and DSD tracks can be played
