- Conexiune de alimentare: Connect the provided power cable to the AC power input on the rear panel and then to a suitable wall outlet. Ensure the voltage selection switch is set correctly for your region (115V/230V).
- Conexiuni Ethernet: The N18 PRO features 5 Gigabit Ethernet ports (LAN1-LAN5) and 1 SFP port. Connect your network devices (e.g., router, NAS, PC, audio streamers) to these ports using standard Ethernet cables.
- Port SFP: For enhanced optical isolation, insert a compatible SFP fiber module into the SFP port. It is recommended to use Gustard's optical modules for optimal performance. Connect an LC-LC fiber cable from the SFP module to your network.
- Intrare ceas 10MHz: For improved audio clarity and analog warmth, connect an external 10MHz clock source to the BNC 10MHz Clock In port. Use the adjacent switch to select between internal (INT) and external (EXT) clock sources.

Instrucțiuni de operare
Pornire/Oprire
After all connections are made, flip the power switch on the rear panel to the 'ON' position. The device will power on and begin network operations.
Funcționarea în rețea
The N18 PRO functions as a network switch, facilitating data transfer between connected devices. Its primary role is to provide a clean and stable network environment for audio streaming by minimizing interference and noise.
- Porturi Ethernet: The 10/100/1000M adaptive Ethernet interfaces automatically detect and adjust to the speed of the connected device.
- Izolare optoelectronică: When using the SFP fiber module, the network ripple is effectively isolated, contributing to a cleaner audio signal.
- Ceas extern: If an external 10MHz clock is connected and selected, it will synchronize the device, enhancing audio clarity and reducing jitter.
Întreţinere
Curatenie
To clean the exterior of the device, use a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the finish or internal components.

Depanare
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Fără putere | Power cable not connected; Power switch off; Blown fuse; Incorrect voltage selecția. | Ensure power cable is securely connected. Turn power switch ON. Check and replace fuse if necessary. Verify voltagComutatorul de selecție este setat corect. |
| Nicio activitate în rețea | Ethernet cables loose or faulty; Connected device is off or misconfigured. | Check all Ethernet cable connections. Ensure connected devices are powered on and configured correctly. Try different Ethernet cables. |
| Calitate audio slabă | Network interference; External clock not properly connected or selected. | Ensure SFP module is used for optical isolation if possible. Verify external 10MHz clock is connected and the 'EXT' option is selected. Check for other sources of electrical interference. |
