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. નો ઉપયોગ કરો ઘડિયાળની પસંદગી switch to select between internal (INT) and external (EXT) clock sources. For an external clock, set the switch to EXT.

૩.૧ કનેક્ટિવિટી વિકલ્પો

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

5. ઓપરેટિંગ સૂચનાઓ

5.1 મૂળભૂત કામગીરી

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.
