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

Review: Great, love this dac - Superb audio dac small works right out of the box with the switch 2, Endeavor Linux, Debian windows and my ps5 so compatible with lots of different things. Sounds as good if not a touch better than my creative ae-7. Make sure you have good quality speakers and headphones to take full advantage of the clear loud sound. Bought an RCA to 2.5mm cable to my speakers with usb-c input from my devices. The dac came with a toslink cable no use to me as it don't use it but it's there.
Review: Amazing sound quality on a budget! - This little amp is a quality product, it arrives well packaged in a smart box with simple instructions and a selection of leads. The leads themselves felt a little bit on the cheap side but perfectly good for the task, I suspect most audiophiles would buy their own leads anyway. The amp itself feels very solid, with an all metal case (no cheap plastic here) that has a nice satin finish, it isn't going to win any style awards with its functional looks, but still manages to convey a pleasing aesthetic that isn't going to look out of place in any setup. The amp was very easy to install and setup, literally plug and play on my PC with no fussy drivers to worry about. It all worked straight out of the box, and it worked very well indeed! The sound is great, with no noise and very clear highs and lows. My onboard sound is pretty decent on my MSI X470 Pro, but I would compare it to the difference between listening to an MP3 and then a FLAC of the same song. Like night and day! Overall this feels like a quality product that punches above its weight in all regards, I was so impressed I immediately bought another one for a family member who appreciates good audio. I don't think you can go wrong at this price point.

### ⭐⭐⭐⭐ Great at what its marketed form but not needed for some types of headphone
*by R***T on 24 June 2025*

Good DAC that adds noticeable sound quality to high impedance headphones. A definite improvement over the motherboard sound card. easy to install, it is literally plug and play and gives good on the fly adjustment to volume & bass. This sits on my desk so is conveniently placed and it is powered by the PC so no external power is needed. Sound clarity is great and there is very little in the way of white noise when using at high volumes. I have found that now I have switched to In Ear Monitors, I don't need the benefits this DAC gives, but this is due to the low impedance of that style of headphone and not the K5. with IEMS I can't get anywhere close to max volume without a substantial amount of blood loss! If you are a true audiophile the K5 may be lacking in features but it is perfect for its advertised use case of gaming and I can absolutely hear the change in audio quality and clarity. directional sound is excellent and really adds to the gaming experience. A bonus was that it shipped with a headphone/microphone splitter cable for those using combined single cables.
