RCA ouput Great sound quality Next-generation DAC for unrivalled performance, make your music sound great at home on your desk. Common Problems and Troubleshooting 1. Not Working Please select the correct input mode for the K5 Pro, ensuring the text displayed when the blue indicator light illuminates matches your audio source. When connecting to a television, set the television's audio output to PCM mode, disable any additional audio effects (such as Dolby or DTS), and select ‘Fosi Audio Digital Output’ as the audio output device. Attempt connecting the device directly to a laptop rather than via a hub; ensure the USB Type-C connector is correctly aligned with the audio source's port. Replace the USB cable to test whether the OTG function is operating correctly. For some devices that may not output enough power to drive the DAC properly, you can try using an additional USB splitter cables for power supply. 2. Only one channel output Make sure all cables are firmly connected, try changing the USB OTG cable. For RCA/AUX output: cross-check the left and right channel speakers and input cable. For headphone output: make sure the headphone plug is fully inserted. Try using different headphones with stereo plugs and 3.5mm cable. In addition, try other input modes to see if the problem persists, and connect to other audio sources to ensure that they output stereo rather than mono. 3. Incompatible headset microphone Confirm that the headset supports the microphone function and enable microphone permissions in the computer's settings (go to "Settings-Microphone-Allow access to your microphone"). In the computer's sound settings, set the "Recording" device to "Fosi Audio K5 PRO". In the input tab in the sound settings, select "Test your microphone" to confirm that the microphone is working properly. In addition, it is recommended to try using a USB power/data cable with OTG function to test different USB ports and headsets. It is recommended to clean the computer port because plug interference may cause partial loss of function. Check the microphone/headphone adapter cable and make sure the volume is turned up. 4. There is noise Check if the noise disappears at lower volumes. Test for interference from nearby devices and use a well-shielded USB OTG cable, avoiding those that run near A/C power cables. Experiment with different input modes (RCA/OPT/COA) to see if the issue persists. If you use a computer, ensure computers and other electrical appliances are not plugged into the same power strip; try using a different one. Consider using a ferrite bead on the power cable and avoid powered external USB hubs. For headphone output noise, try a 3.5mm ground loop isolator and use higher impedance headphones. Place the device in a dry, well-ventilated location. Product Comparison K5 PRO Q4 SK01 SK02 DS1 DS2 PH05
