Product Features
3-Level Digital Signal Gain Adjustment
The UC10 offers three selectable digital signal gain levels: High, Medium, and Low (3Vpp, 2Vpp, 1Vpp respectively for unloaded output). This feature ensures optimal compatibility with various digital inputs on different audio systems.

The UC10 supports a wide range of high-resolution audio formats and rates. It can handle maximum input formats/rates of 768kHz/24Bit, DoP DSD256, and Native DSD512. The maximum output formats/rates are 192kHz/24Bit and DoP DSD64, providing audio quality that exceeds standard CD quality for a realistic HiFi experience.

Setup Instructions
- Connect to Source Device: Use the provided Type-C to Type-C adapter cable to connect the HiBy UC10 to the USB-C port of your smartphone, DAP, or computer. Ensure the connection is secure.
- Connect to Receiving Device: Connect a 3.5mm coaxial S/PDIF cable (not included) from the 3.5mm coaxial digital output port of the UC10 to the coaxial digital input of your DAC, amplifier, or other HiFi system.
- Power On: The UC10 draws power from the connected USB source device and will power on automatically once connected.
- Driver Installation (for Computers): For Windows 10/11, the device typically works with default drivers. For other operating systems or specific advanced features, refer to the HiBy official website for any necessary driver downloads.
Operating Instructions
The HiBy UC10 features a single function (Fn) button for controlling key settings:
- Single-tap Fn button: This action cycles through the digital output voltage gain levels (Low, Medium, High). Select the appropriate gain level for compatibility with your connected audio equipment.
- Long-press Fn button: This action switches between D2P (DSD to PCM conversion) and DoP (DSD over PCM) modes. Choose the mode that is compatible with your receiving DAC or amplifier for DSD audio playback.
Once connected and configured, simply play audio from your source device. The UC10 will process and output the digital audio signal to your connected HiFi system.
Maintenance
- Keep the device clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Store the UC10 in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Avoid dropping the device or subjecting it to strong impacts.
- Do not attempt to disassemble or modify the device, as this will void the warranty and may cause damage.
Troubleshooting
- No Audio Output:
- Ensure all cables (USB-C and coaxial) are securely connected.
- Verify that the source device (smartphone, DAP, computer) is playing audio and its volume is not muted or too low.
- Check the input selection on your receiving DAC or amplifier to ensure it is set to the correct coaxial input.
- If using a computer, confirm that the HiBy UC10 is selected as the audio output device in your sound settings.
- Try adjusting the gain level on the UC10 using the Fn button.
- If playing DSD audio, ensure the UC10 is in the correct D2P or DoP mode compatible with your DAC.
- Intermittent Signal / Dropping Audio:
- Check for loose cable connections.
- Ensure the USB-C port on your source device is clean and free of debris.
- Test with a different USB-C cable or coaxial cable if available.
- Ensure the source device has sufficient power; low battery can sometimes affect USB audio stability.
- Device Not Recognized by Computer:
- Try connecting to a different USB port on your computer.
- Restart your computer.
- For Windows 7/8 or specific configurations, you may need to manually install drivers from the HiBy official website.
