4. Einrichtung
4.1 Anschlüsse auf der Rückseite
Familiarize yourself with the rear panel connections before setting up the device.

4.2 Stromanschluss
- Stellen Sie sicher, dass Bandtage-Auswahl Der Schalter auf der Rückseite ist auf die richtige Lautstärke eingestellt.tage for your region (e.g., 115V AC).
- Verbinden Sie das mitgelieferte Netzkabel mit dem Wechselstrom input on the rear panel and then to a suitable wall outlet.
- Drücken Sie die Netzschalter um das Gerät einzuschalten.
4.3 Netzwerkverbindungen
The N18 PRO offers various network connectivity options:
- RJ45 Ethernet Ports: Connect your network devices (e.g., router, NAS, PC, audio streamers) to the Ethernet-Anschlüsse (LAN1-LAN5) using standard Ethernet cables.
- SFP Fiber Connector: For optical fiber connections, insert a compatible SFP module into the SFP-Port. This provides enhanced isolation from network noise.
4.4 External 10MHz Clock Connection
For optimal audio performance, an external 10MHz clock can be connected:
- Connect your external 10MHz clock source to the Clock in BNC connector on the rear panel.
- Verwenden Sie die Auswahl der Uhr switch to select between internal (INT) and external (EXT) clock sources. For an external clock, set the switch to EXT.
4.5 Konnektivitätsoptionen
The N18 PRO can be integrated into various network audio setups. Below are examples of common configurations:


5. Bedienungsanleitung
5.1 Grundlegende Bedienung
- After connecting all necessary cables and power, turn on the N18 PRO using the power switch on the rear panel.
- The device will automatically establish network connections. No further configuration is typically required for basic network switching.
5.2 Network Signal Flow
The N18 PRO acts as an intelligent network switch, optimizing the data flow for connected audio devices. Its internal design minimizes noise and interference, providing a cleaner digital signal to your streamers, DACs, and other network-enabled audio components.
5.3 External Clock Usage
If an external 10MHz clock is connected and selected via the rear panel switch, the N18 PRO will synchronize its internal timing with the external clock. This can lead to improved precision in data transmission and a more refined audio output from connected devices.
6. Wartung
- Reinigung: Reinigen Sie die Außenseite des Geräts mit einem weichen, trockenen Tuch. Verwenden Sie keine flüssigen Reiniger oder Sprays.
- Belüftung: Ensure adequate ventilation around the device. Do not block any ventilation openings.
- Umfeld: Operate the device in a clean, dry environment, away from direct sunlight and heat sources.
- Kabelmanagement: Überprüfen Sie regelmäßig alle Kabelverbindungen, um sicherzustellen, dass sie fest sitzen und keine Beschädigungen aufweisen.
7. Fehlerbehebung
7.1 Kein Strom
- Check if the power cable is securely connected to both the device and the wall outlet.
- Vergewissern Sie sich, dass sich der Netzschalter auf der Rückseite in der Position „EIN“ befindet.
- Inspect the fuse on the rear panel. If blown, replace it with a fuse of the same type and rating.
- Stellen Sie sicher, dass die Lautstärketage selection switch matches your local power supply.
7.2 Keine Netzwerkverbindung
- Check all Ethernet or SFP cable connections between the N18 PRO and your network devices/router.
- Ensure your router and connected devices are powered on and functioning correctly.
- If using the SFP port, verify that the SFP module is correctly inserted and compatible.
- Try restarting the N18 PRO and your connected network devices.
7.3 Schlechte Audioqualität
- Ensure all audio components connected to the network are properly configured.
- If using an external clock, verify it is connected correctly and the Auswahl der Uhr switch is set to EXT.
- Check for any external interference sources near the N18 PRO or audio cables.
