This article describes the basic configuration on how to get started with the ENA Amplifier used with the ICX-AlphaCom server. For a more detailed description of various settings and options, see [[ENA Configuration - ICX-AlphaCom mode]]

== License requirement ==
The ENA amplifier supports up to 3 channels. Two channels for the two loudspeaker lines, and one channel for Microphone In/Line In.
* Each channel in use requires an [[Licenses_for_ICX-500_and_ICX-AlphaCom_Core|ENA Amplifier Channel License (ILS-AMP)]]. 
** When using [[ENA2x00-AC2 - One Channel Mode|One Channel mode]], only one ENA Amplifier Channel License is required. 

To install the license, [[ICX_Web#Logging_in|log on to the web interface]] of the ICX-AlphaCom server, and select '''System Configuration''' > '''Licensing'''.

== Configure the amplifier ==

==Volume control==

* Output channels volume can be controlled from the [[ENA User Interface|amplifier GUI]] or the web interface ([[ENA_Configuration_-_ICX-AlphaCom_mode#Line_Control|Amplifier Settings > Line Control > Channel 1/Channel 2 > Master Volume]])
* Input audio channel gain can be controlled from [[ENA User Interface|amplifier GUI]] or the web interface
* Web and GUI settings are in sync, and will automatically update if changed in either place. 
* Each channel have individual volume control, even if the two channels are combined into one channel.
