5. Configuració

This section guides you through the physical installation and initial configuration of your Snom PA1.

5.1. Muntatge

The Snom PA1 can be placed on a flat surface or mounted using the integrated mounting tabs. Ensure the location allows for proper ventilation and easy access to ports.

5.2. Connexió d'alimentació i xarxa

1. Connect an Ethernet cable from your network switch (preferably PoE-enabled) to Port 1 PoE on the rear panel of the Snom PA1. If using a non-PoE switch, connect an external 5V DC power adapter to the 5V DC port.
2. The Power LED should illuminate, indicating the device is receiving power.

5.3. Connexió d'altaveus

The Snom PA1 can drive speakers directly or act as a preamp for larger systems.

• For Small PA Systems (Internal Ampmés viu): Connect an 8-ohm speaker directly to the Altaveu terminals on the front panel. Ensure correct polarity (red to positive, black to negative). The internal 4-watt amplifier is suitable for single or a few speakers.
• For Large PA Systems (External Ampmés viu): Connecteu el Sortida de línia 3.5mm jack on the front panel to the audio input of your external high-wattage amplificador. L'exterior amplifier will then drive the speakers.

5.4. Microphone and I/O Connections

• Micròfon: Connect a compatible microphone to the Entrada de micròfon 3.5mm jack for two-way communication or announcements.
• Ports d'E/S: Utilitza el E/S 1 i E/S 2 ports to connect external devices such as door openers, relays, or sensors, depending on your system's requirements. Refer to the Snom documentation for specific wiring and configuration details for these ports.

5.6. Configuració inicial (Web Interfície)

After physical setup, the Snom PA1 requires network configuration and SIP registration. The device obtains an IP address via DHCP by default.

1. To find the IP address, you may use a network scanner or consult your DHCP server logs. Alternatively, some Snom phones can display the IP address of connected PA1 units.
2. Obre a web browser and enter the IP address of the Snom PA1.
3. Log in using the default credentials (consult the Quick Start Guide or Snom documentation for default username and password).
4. Navigate to the SIP settings to register the PA1 as an extension on your SIP PBX. Configure the necessary account details (SIP identity, password, server address).
5. Adjust audio settings, including speaker volume and amplifier gain, as needed for your specific speaker setup.
