3. Упутства за подешавање
- Идентификујте портове: Locate an available USB-C port on your host device (e.g., laptop, desktop computer, Android phone/tablet).
- Connect Isolator to Host: Plug the USB-C male connector of the SH-G01C isolator into the USB-C port of your host device.
- Connect Peripheral Device: Connect your USB peripheral device (e.g., HiFi DAC, audio interface, development board) to the USB Type A female port on the SH-G01C isolator.
- Потврдите везу: The device is plug-and-play and typically requires no driver installation. Your operating system should automatically recognize the connected peripheral device through the isolator.

4. Упутство за употребу
Once connected, the DSD TECH SH-G01C operates transparently, providing a high-speed isolated USB 2.0 connection. It functions as an intermediary device, ensuring that electrical noise and ground loops from the host system do not interfere with the connected peripheral. This is particularly beneficial for audio equipment where noise can degrade sound quality.
Noise Reduction Principle
The isolator uses advanced chip technology (ADI ADUM3165) to electrically separate the ground planes of the host and peripheral devices. This prevents unwanted current flows (ground loops) that often manifest as hums, buzzes, or static in audio systems, or as data corruption in sensitive data transfer applications.

5. Одржавање
The DSD TECH SH-G01C is a low-maintenance device. To ensure its longevity and optimal performance:
- Одржавајте уређај чистим и без прашине. Користите меку, суву крпу за чишћење.
- Избегавајте излагање уређаја екстремним температурама, влажности или директној сунчевој светлости.
- Do not apply excessive force when connecting or disconnecting cables to prevent damage to the connectors.
- Чувајте уређај на безбедном месту када га не користите како бисте спречили физичка оштећења.
КСНУМКС. Решавање проблема
- Уређај није препознат: Ensure both the USB-C connector to the host and the USB-A connector to the peripheral are securely plugged in. Try connecting the peripheral directly to the host to confirm the peripheral is functional.
- Noise Persists: While the SH-G01C is designed to eliminate ground loop noise, other sources of interference may exist. Ensure all audio cables are shielded and properly routed away from power cables. Test the setup with different USB ports or host devices if possible.
- Интермитентна веза: Check for any physical damage to the cables or connectors. Ensure the host device's USB-C port is functioning correctly.
- Спори пренос података: The SH-G01C supports USB 2.0 High-Speed (480Mbps). If you are experiencing slower speeds, ensure your peripheral device is also operating at USB 2.0 speeds and that your host system's USB-C port is configured for optimal performance.
