AlphaCom with ENA Amplifiers

This article describes the configuration required for a Exigo Network Amplifier (ENA) to operate with an AlphaCom server. The ENA Amplifiers are configured through their web interface. The AlphaCom server is configured using the PC tool AlphaPro.

Quick getting started guide

To make an ENA Amplifier operational there are essentially four parameters to set in the web interface of the amplifier. Log In to the amplifier, go to Station Main > Main Settings, and:

Set Station Mode = "Use AlphaCom"
Configure the IP Settings (IP address) of the amplifier
Enter the AlphaCom IP-address
Enter Ch1 Directory Number

The Directory Number must also be defined in the AlphaCom Server using the AlphaPro configuration tool.

Log in to the Amplifier

Access the amplifier by logging into the web interface using a standard web browser:

1. Open a web browser on your PC

2. In the browser’s address bar, type the IP address of the amplifier. The login page will be displayed.

3. Enter Username and Password. Default username: admin. Default password: alphaadmin

The information page will now be displayed, showing the main configuration and status.

To find the IP address of the amplifier, use the Menu Selection Knob on the front of the amplifier, and navigate to Information > Network.

Main Settings

Click Station Main > Main Settings to access the page for configuring station mode and IP parameters.

Station Mode: Select the Use Alphacom radio-button.

Registration Settings:

AlphaCom IP-address: Enter the IP address of the AlphaCom server to which the amplifier is to be registered

The amplifier has up to three directory numbers you can configure: Channel 1, Channel 2 and Audio Input. Each of these require a license.

CH1 Out Directory Number: Mandatory: Enter the directory number of the first loudspeaker output channel. The number must match the directory number defined in the AlphaCom server
CH2 Out Directory Number: Optional: If the second loudspeaker channel should be addressed separately, the second channel must be registered to the AlphaCom using this directory number
Audio In Directory Number: Optional: If the Line In is to be used from the amplifier, the input must be registered to the AlphaCom using this directory number

IP Settings:

DHCP – Select this option if the IP station shall receive IP Settings from a DHCP server.
Static IP – Select this option if the IP station shall use a static IP address. Enter values for:

- IP-address

- Subnet-mask

- Gateway

- DNS Server 1 (option for network administration)

- DNS Server 2 (option for network administration)

- Hostname (option for network administration)

Disable Reset to Factory default settings using frontboard and I/O: If enabled, factory reset will only be possible from the web interface. This is disabled by default.

Read IP Address: Not in use

Enable RSTP: RSTP is only required when using redundant networking

Click Save followed by Apply to apply the new configuration settings.

Time Settings

Select Advanced AlphaCom > Time Settings from the menu

Time Settings: You can enable Network Time Protocol, select the time zone and set the hostname or the IP address of the NTP server.

Logging

From the web interface of the amplifier it is possible to activate logging, which can be useful for debugging and troubleshooting purposes. See Logging - IP Stations for more information.
