3. Opsætning

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

1. Udpakning: Carefully remove the N18 PRO from its packaging. Ensure all accessories are present.
2. Placering: Place the N18 PRO on a stable, flat surface with adequate ventilation. Avoid placing it near heat sources or in direct sunlight.
3. Strømtilslutning: 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. Netværksforbindelser:
   • 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. Tænd: Flip the power switch on the rear panel to the 'ON' position. The device will power on.

Tilslutningsmuligheder

The Gustard N18 PRO can be integrated into various network configurations. Below are common setup diagrams:

Option 1: N18 + N18 PRO (Recommended)
This diagram illustrates a recommended connectivity option where the Gustard N18 and N18 PRO are used together. It shows how a router, NAS, and PC connect to the N18, which then connects to the N18 PRO, distributing signals to various audio equipment like DACs and streamers.

Option 5: N18 PRO Standalone
This diagram shows a connectivity option where only the Gustard N18 PRO is used. It details how a router, NAS, and PC connect directly to the N18 PRO, which then routes signals to various audio components.

4. Betjeningsvejledning

The Gustard N18 PRO is designed for straightforward operation:

• Once all connections are made and the device is powered on, the N18 PRO will automatically begin functioning as a network switch.
• No specific software or configuration is typically required for basic network switching functionality.
• Ensure that all connected audio devices are properly configured to receive network signals from the N18 PRO.
• If an external 10MHz clock is connected, verify that the 'Clock selection' switch on the rear panel is set to 'EXT' to utilize the external clock source. For internal clock, set it to 'INT'.

5. Vedligeholdelse

To ensure the longevity and optimal performance of your Gustard N18 PRO, observe the following maintenance guidelines:

• Rensning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners, aerosols, or abrasive materials, as they may damage the finish or internal components.
• Ventilation: Ensure that the ventilation openings are not blocked. Proper airflow is essential to prevent overheating.
• Miljø: Keep the device in a dry environment, away from excessive dust, humidity, and extreme temperatures.
• Sluk: If the device will not be used for an extended period, it is recommended to power it off and disconnect it from the mains power supply.

6. Fejlfinding

If you encounter issues with your Gustard N18 PRO, refer to the following common troubleshooting steps:

• Ingen strøm:
  • Check if the power cable is securely connected to both the N18 PRO and the wall outlet.
  • Sørg for, at tænd/sluk-knappen på bagpanelet er i 'ON'-positionen.
  • Kontroller, at stikkontakten fungerer korrekt ved at tilslutte en anden enhed.
  • Check the fuse on the rear panel. If blown, replace it with a fuse of the same type and rating.
• Ingen netværksforbindelse:
  • Ensure all Ethernet cables are securely plugged into their respective ports on the N18 PRO and connected devices.
  • Verify that your router or upstream network device is functioning correctly.
  • If using the SFP port, ensure the SFP module is correctly inserted and the fiber optic cable is not damaged.
  • Check the network status indicators on the N18 PRO and connected devices.
• Poor Audio Quality / Noise:
  • Ensure all audio components are properly connected and functioning.
  • If using an external clock, verify its connection and ensure the 'Clock selection' switch is set to 'EXT'.
