• SFP Port: For connecting an SFP optical converter module, providing optoelectronic isolation.
• LAN Ports (LAN1, LAN2): 10/100/1000M adaptive Ethernet interfaces for network devices.
• AC Power Input: Connect the provided power cable.
• Power Switch: To turn the unit on or off.
• Voltage Selection: Ensure this is set correctly for your region (e.g., 115V or 230V).

Connectivity Options:

The N18 can be integrated into various network configurations. Below are common setup options:

Option 1: N18 + N18pro (Recommended) - Connects N18 to router, and N18pro to N18, then to audio devices. This setup provides enhanced isolation.

Option 2: N18pro + N18pro - Utilizes two N18pro units for comprehensive network management and audio device connectivity.

Option 3: N18 + N18 - Connects two N18 units for expanded network switching capabilities.

Option 4: Single N18 - Basic setup where the N18 connects directly to your router and audio devices.

Option 5: Single N18pro - Setup using only the N18pro for network and audio connections.

For optimal performance, it is recommended to use Gustard's optical modules when utilizing the SFP interface.

The SFP optoelectronic converter module provides optical isolation for cleaner signal transmission. Accessories like SFP modules and LC-LC Fiber are sold separately.

Customized C2 clock cables are available separately for improved performance, providing a cleaner sound and more analog sense.

3. Operating Instructions

Once the Gustard N18 is properly connected, operating it is straightforward. The device is designed for plug-and-play functionality within your network.

Powering On/Off:

1. Ensure the voltage selection switch on the rear panel is set to the correct voltage for your region (115V or 230V).
2. Connect the AC power cable to the unit and a wall outlet.
3. Flip the power switch on the rear panel to the 'ON' position. The unit will power up.
4. To power off, flip the power switch to the 'OFF' position.

Network Operation:

The N18 functions as a transparent network switch. Once connected, it will automatically manage data flow between your network devices and audio components, providing a cleaner signal path for audio streaming.

The internal design, including the high current low voltage drop rectifier bridge, Nichicon filter capacitors, and multi-stage voltage regulators, works to minimize interference and provide stable, clean power for optimal audio performance.

4. Maintenance

To ensure the longevity and optimal performance of your Gustard N18, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the unit. Avoid using liquid cleaners or abrasive materials, which may damage the finish.
• Ventilation: Ensure the unit has adequate ventilation. Do not block any ventilation openings.
• Environment: Keep the unit in a cool, dry place, away from direct sunlight, heat sources, and excessive dust or moisture.
• Connections: Periodically check all cable connections to ensure they are secure.

5. Troubleshooting

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

• No Power:
  • Check if the power cable is securely connected to both the unit and the power outlet.
  • Ensure the power switch on the rear panel is in the 'ON' position.
  • Verify the voltage selection switch is set correctly for your region.
  • Check the fuse on the rear panel. If blown, replace it with a fuse of the same type and rating.
• No Network Connectivity:
  • Ensure Ethernet cables are securely connected to both the N18 and your network devices/router.
  • If using the SFP port, ensure the SFP module is correctly inserted and the fiber optic cable is properly connected.
  • Restart the N18 by cycling the power switch.
  • Check the status indicators on your connected devices and the N18 (if any) for network activity.
• Poor Audio Quality:
  • Ensure all audio components connected to the network are properly configured.
  • Verify that the N18 is receiving clean power and is not subject to electrical interference.
  • Consider using high-quality Ethernet and optical cables.

If the issue persists after following these steps, please contact AOSHIDA customer support for further assistance.
