Follow these steps to set up your Gustard N18 PRO network switch:

1. আনপ্যাকিং: Carefully remove the N18 PRO from its packaging. Ensure all accessories are present.
2. বসানো: Place the N18 PRO on a stable, flat surface with adequate ventilation. Avoid placing it near heat sources or in direct sunlight.
3. পাওয়ার সংযোগ: Connect the provided power cable to the AC power input on the rear panel of the N18 PRO. Ensure the voltage selection switch (if present and adjustable) matches your local power supply (e.g., 115V or 230V).
4. নেটওয়ার্ক সংযোগ:
   • Connect your internet router or main network switch to the 'Internet' Ethernet port (LAN5) or the SFP port using an appropriate Ethernet cable or SFP module with fiber optic cable.
   • Connect your audio streaming devices (e.g., network streamers, DACs with network input) to the 'Acoustic equipment' Ethernet ports (LAN1-LAN4).
   • If using an external 10MHz clock, connect it to the '10MHz IN' BNC connector. Ensure the clock selection switch is set to 'EXT' for external clock usage.
5. পাওয়ার চালু: Flip the power switch on the rear panel to the 'ON' position. The device will power on.
