4. Nastavenie
4.1 Pripojenia zadného panela
Familiarize yourself with the rear panel connections before setting up the device.

4.2 Pripojenie napájania
- Zabezpečte Voltage výber prepínač na zadnom paneli je nastavený na správnu hlasitosťtage for your region (e.g., 115V AC).
- Pripojte dodaný napájací kábel k Napájanie striedavým prúdom input on the rear panel and then to a suitable wall outlet.
- Stlačte tlačidlo Vypínač napájania na zapnutie zariadenia.
4.3 Sieťové pripojenia
The N18 PRO offers various network connectivity options:
- Ethernetové porty RJ45: Connect your network devices (e.g., router, NAS, PC, audio streamers) to the Ethernetové porty (LAN1-LAN5) using standard Ethernet cables.
- SFP Fiber Connector: For optical fiber connections, insert a compatible SFP module into the Port SFP. 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.
- Použite Výber hodín switch to select between internal (INT) and external (EXT) clock sources. For an external clock, set the switch to EXT.
4.5 Možnosti pripojenia
The N18 PRO can be integrated into various network audio setups. Below are examples of common configurations:


5. Návod na obsluhu
5.1 Základné ovládanie
- 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. Údržba
- Čistenie: Na čistenie vonkajšieho povrchu zariadenia používajte mäkkú, suchú handričku. Nepoužívajte tekuté čistiace prostriedky ani aerosóly.
