4. Asennus

4.1 Takapaneelin liitännät

Familiarize yourself with the rear panel connections before setting up the device.

4.2 Virtaliitäntä

1. Varmista, että Voitage valinta takapaneelin kytkin on asetettu oikealle äänenvoimakkuusasetukselletage for your region (e.g., 115V AC).
2. Liitä mukana toimitettu virtajohto pistorasiaan AC virta input on the rear panel and then to a suitable wall outlet.
3. Paina Virtakytkin käynnistääksesi laitteen.

4.3 Verkkoyhteydet

The N18 PRO offers various network connectivity options:

• RJ45 Ethernet-portit: Connect your network devices (e.g., router, NAS, PC, audio streamers) to the Ethernet-portit (LAN1-LAN5) using standard Ethernet cables.
• SFP Fiber Connector: For optical fiber connections, insert a compatible SFP module into the SFP-portti. This provides enhanced isolation from network noise.

4.4 External 10MHz Clock Connection

For optimal audio performance, an external 10MHz clock can be connected:

1. Connect your external 10MHz clock source to the Clock in BNC connector on the rear panel.
2. Käytä Kellon valinta switch to select between internal (INT) and external (EXT) clock sources. For an external clock, set the switch to EXT.

4.5 Yhteysvaihtoehdot

The N18 PRO can be integrated into various network audio setups. Below are examples of common configurations:

5. Käyttöohjeet

5.1 Peruskäyttö

1. After connecting all necessary cables and power, turn on the N18 PRO using the power switch on the rear panel.
2. 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. Huolto

• Puhdistus: Puhdista laitteen ulkopinta pehmeällä, kuivalla liinalla. Älä käytä nestemäisiä puhdistusaineita tai aerosoleja.
• Ilmanvaihto: Ensure adequate ventilation around the device. Do not block any ventilation openings.
• Ympäristö: Operate the device in a clean, dry environment, away from direct sunlight and heat sources.
• Kaapelin hallinta: Tarkista säännöllisesti kaikki kaapeliliitännät varmistaaksesi, että ne ovat tukevasti kiinni ja ehjät.

7. Vianmääritys

7.1 Ei virtaa

• Check if the power cable is securely connected to both the device and the wall outlet.
• Varmista, että takapaneelin virtakytkin on 'ON'-asennossa.
• Inspect the fuse on the rear panel. If blown, replace it with a fuse of the same type and rating.
• Varmista voltage selection switch matches your local power supply.

7.2 Ei verkkoyhteyttä

• 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 Huono äänenlaatu

• Ensure all audio components connected to the network are properly configured.
• If using an external clock, verify it is connected correctly and the Kellon valinta switch is set to EXT.
• Check for any external interference sources near the N18 PRO or audio cables.
