4.3ネットワーク接続

The N18 PRO offers various network connectivity options:

RJ45 Ethernet Ports: Connect your network devices (e.g., router, NAS, PC, audio streamers) to the イーサネットポート (LAN1-LAN5) using standard Ethernet cables.
SFP Fiber Connector: For optical fiber connections, insert a compatible SFP module into the SFPポート. 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.
使用 時計の選択 switch to select between internal (INT) and external (EXT) clock sources. For an external clock, set the switch to EXT.

4.5 接続オプション

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

Diagram showing connectivity option 1 with N18 and N18 PRO — Figure 4.2: Connectivity Option 1 (Recommended) - Utilizing both N18 and N18 PRO units for enhanced network isolation and port expansion. The router connects to the N18, which then connects to the N18 PRO, distributing signals to various audio devices.

Diagram showing connectivity option 5 with N18 PRO only — Figure 4.3: Connectivity Option 5 - Using only the N18 PRO. The router connects directly to the N18 PRO, which then connects to your audio devices, NAS, and PC.

5. 操作手順

5.1 基本操作

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. メンテナンス

クリーニング： デバイスの外側を清掃する際は、柔らかく乾いた布をご使用ください。液体クリーナーやエアゾールは使用しないでください。
換気： Ensure adequate ventilation around the device. Do not block any ventilation openings.
環境： Operate the device in a clean, dry environment, away from direct sunlight and heat sources.
ケーブル管理 すべてのケーブル接続が安全で損傷がないことを定期的に確認してください。

7。トラブルシューティング

7.1 電源なし
