- Sambungan Kuasa: 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).
- Sambungan 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.
- Pelabuhan 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.
- 10MHz Clock Input: 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.

Arahan Operasi
Hidupkan/Mati Kuasa
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.
Operasi Rangkaian
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.
- Port Ethernet: The 10/100/1000M adaptive Ethernet interfaces automatically detect and adjust to the speed of the connected device.
- Optoelectronic Isolation: When using the SFP fiber module, the network ripple is effectively isolated, contributing to a cleaner audio signal.
- Jam Luaran: If an external 10MHz clock is connected and selected, it will synchronize the device, enhancing audio clarity and reducing jitter.
Penyelenggaraan
Pembersihan
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.
