How to use
Connect the quer KOM0638 sound card to an available USB port on your computer or compatible host device. The operating system should detect the device automatically and assign it as an additional audio endpoint. Select the new USB audio device in the system sound settings or in the desired application for playback or recording. Plug headphones or speakers into the output jack and an external microphone into the input jack as required. For recording, open your audio application, choose the quer device as the recording source, and start capture; for playback, route audio output to the quer device.
Usage recommendations
Use short, high-quality USB cables and avoid using multiple passive USB hubs between the sound card and the host to reduce the risk of signal issues. For the best audio experience, use headphones or speakers with suitable impedance and set system levels to avoid clipping. If the host system offers selectable sample rates, choose the rate supported by your application and the quer device for stable operation.
