• ОПТИКАЛЫК: Optical (Toslink) digital audio output.
• USB IN: USB 2.0 input for connection to a computer.

4. Орнотуу нускамалары

1. Кубат туташуу: Connect the provided power cable to the 230V/115V AC input on the rear panel of the U12 and then to a suitable power outlet.
2. USB туташуу: Connect a USB cable from your computer (Windows, macOS, or Linux) to the USB IN port on the rear panel of the U12.
3. Санарип чыгуу байланышы: Connect one of the digital outputs (Coaxial, Optical, AES/EBU, or IIS) from the U12 to the corresponding digital input on your Digital-to-Analog Converter (DAC) or audio ampөмүрлүү.
4. Driver Installation (Windows Users):
   • Insert the provided mini-CD into your computer's CD drive.
   • Locate and install the XMOS driver. A common driver version is 4.13.0 (e.g., "XMOS-Stereo-USB-Audio-Class2-Driver-3033_v4.13.0").
   • Драйверди орнотууну аяктоо үчүн экрандагы көрсөтмөлөрдү аткарыңыз. Суралса, компьютериңизди өчүрүп-күйгүзүңүз.
   • For optimal performance, it is recommended to use ASIO output when configuring your audio playback software (e.g., jRiver Media Player, Foobar2000).
5. Driver Installation (macOS/Linux Users): The U12 is generally plug-and-play with macOS and Linux operating systems, requiring no additional driver installation.
6. Баштапкы күйгүзүү: Once all connections are secure and drivers are installed (if applicable), the U12 will power on automatically when the computer is turned on or when the USB cable is connected. The front display will show the current sampле чен.

5.1 Аудио ойнотуу

After successful setup, select the Gustard U12 as your audio output device in your computer's sound settings or preferred audio playback software. Begin playing audio, and the U12 will automatically detect and display the incoming sample rate on its front panel.

5.2 Supported Output Formats and Sample Rates

• Coaxial (RCA), Optical, AES/EBU: These outputs conform to IEC60958 and AES3-r2009 standards, supporting a maximum resolution of 24-bit / 192kHz.
• IIS (HDMI port): This output can transmit up to 32-bit / 384kHz audio.

The U12 employs two independent active crystals to provide precise clock signals for different sample rate series: one for 44.1/88.2/176.4/352.8kHz and another for 48/96/192/384kHz. Only the crystal corresponding to the selected clock rate operates, preventing mutual interference.

5.3 Электр энергиясын башкаруу

The U12 features an automatic standby mode. When your computer enters sleep mode or is powered off (provided the USB power is also off), the U12's display will turn off. Waking your computer or restoring USB power will instantly reactivate the U12 and its display.

6. Техникалык тейлөө

To ensure the longevity and optimal performance of your Gustard U12, follow these maintenance guidelines:

• Тазалоо: Түзмөктүн сыртын сүртүү үчүн жумшак, кургак чүпүрөктү колдонуңуз. Суюк тазалоочу каражаттарды же абразивдүү материалдарды колдонуудан алыс болуңуз, анткени алар капталына зыян келтириши мүмкүн.
• Жайгашкан жери: Place the U12 on a stable, flat surface with adequate ventilation. Avoid placing it near heat sources, direct sunlight, or in areas with high humidity.
• Өчүрүү: If the unit will not be used for an extended period, it is advisable to unplug it from the power outlet.
• Ички компоненттери: Do not attempt to open the unit or service it yourself. Refer all servicing to qualified personnel. Opening the unit may void your warranty.
