{{AI}} [[File:ENA2 Amp block.png|thumb|800px|ICX-AlphaCom with ENA Amplifiers]] 
This article describes the configuration required for the Zenitel IP Amplifiers (ENA2100-AC2 & ENA2200-AC2)  to operate with an '''ICX-AlphaCom''' server. The ENA Amplifiers are configured through their web interface. The ICX-AlphaCom server is configured using the PC tool [[AlphaPro]].

==Software and License requirements ==
=== Minimum Software requirement ===
* '''ENA Amplifier''': 4.9.3.0

AlphaCom XE series
* '''AlphaCom''': 12.5.3.0
* '''AlphaPro''': 11.7.3.2

ICX-AlphaCom
* '''ICX-AlphaCom''': 1.1.3.0
* '''AlphaPro''': 12.1.3.0

=== License requirement ===
* One [[Licenses#Exigo_.28ENA.29_Amplifier_license|ENA Amplifier Channel License]] is required per amplifier channel or audio in channel. 
** <span style="font-size:90%">For example, if Channel 1, Channel 2 and Audio In all have their own directory numbers, then 3 [[Licenses#Exigo_.28ENA.29_Amplifier_license|ENA Amplifier Channel License]] are required</span>
* To enable the use of Background Music at 48 kHz PCM, a [[Licenses#High_bandwidth_audio_license|High bandwidth audio license]] is required. It is sufficient with one HD Audio license per ICX-AlphaCom server.

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

== Directory Numbers ==
The ENA Amplifier supports 3 registrations on 3 separate directory numbers:
* First registration:  CH1 audio output, RCO, RCI control and fault status monitoring
* Second registration: CH2 audio output
* Third registration: Mic In or Line in audio input
<br>

== The amplifier web interface==

**'''Disabled''' option will disable this channel registration
**'''Mirror CH1 audio''' will play CH1 audio stream on CH2, and CH2 will not require directory number and will not use any license
**When channel is mirrored, channel monitoring and volume controls (in web and GUI) are still separate
* '''Audio In Directory Number''': The third registered channel. This channel is used to send mic or line in audio to the ICX-AlphaCom
** '''Disabled''' option will disable this channel registration

'''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)

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

=== Advanced ICX-AlphaCom tab===
==== DAVC Settings ====
The Distributed Automatic Volume Control (DAVC) is an algorithm which is using one or more microphones to measure the ambient audio/noise level, and adjust the loudspeaker output level of the PA amplifier according to the ambient audio level. See [[Distributed Automatic Volume Control (DAVC)]] for more details.

====Time Settings====

A set of SNMP functions are available in the IP station. SNMP (Simple Network Management Protocol) is a protocol for centralizing the management of devices in IP networks.

See [[SNMP in IP Stations]] for futher information.

==== 802.1X ====
IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN, either establishing a point-to-point connection or preventing it if authentication fails. For details on configuration, see [[IEEE 802.1X]].

* '''Pilot Tone Sensing''' Enables or disables the Line In Pilot Tone Sensing.

==== Testing ====
There are two tests that can be run:
* '''LEDs''': Makes the four status LEDs (Power, Amp, Fault and GND) flash for 5 seconds
* '''Fault Relay''': Turns on the Fault Relay for 5 seconds

==== IO Monioring ====
There are 3 Control Outputs (RCO/GPO) and 2 Control Inputs (RCI/GPI) available. The GPO's are controlled as pin 1, 2 and 3. The GPI's report as input 1 and 2 to the ICX-AlphaCom.

'''Configuration''' of the outputs and inputs is done from [[AlphaPro]]:
* The '''Control Output''' must be mapped to a [[RCO - Remote Control Output|Logical RCO]]. The operation of the logical RCOs is configured in the [[Event Handler]] window.
* The '''Control Input''' is configured in the [[RCI_-_Remote_Contol_Input#Inputs_from_AlphaCom.2C_ENA_Amplifier.2C_IPARIO_and_RIO|RCI table in AlphaPro]]

The ENA amplifier offers monitoring of the outputs and the inputs:
* '''RCO/GPO''' monitoring alerts when the signal on the contacts are outside the configured legal values. 
[[File:ENA RCO Monitoring.png|thumb|left|700px|The '''RCO/RCI Config''' page]]
<br style="clear:both;" />

*'''Limit Low OK''' - If the RCO triggers and the voltage is below this value, it is reported as "Shorted".
*'''Limit High Not OK''' - If the RCO is not above this voltage when output is high, it is reported as an "Overload".
The RCOs/GPOs can be tested from this page. They can be set and cleared. Remember to set them back to '''System''' before ending the test.
[[File:ENA RCO Test.png|thumb|left|700px|The '''RCO/RCI Config''' page]]
<br style="clear:both;" />

* '''RCI/GPI''' config allows configuring the thresholds for when the RCI triggers. An RCI has an open voltage of 10V across the terminals. [[ENA_Amplifier_-_Mounting_and_Installation#Control_Inputs|A resistor network]] is needed to ensure that RCI's can be monitored properly.    
[[File:ENA RCI Monitoring.png|thumb|left|700px|The '''RCO/RCI Config''' page]]
<br style="clear:both;" />
* '''Monitor RCI''' enables monitoring of RCI.
* '''Not Connected''' - When the voltage on the pin is higher than this threshold, it's set as Not Connected.
* '''Not Pressed''' - Low threshold for the RCI to be considered not pressed.
* '''Pressed''' - High threshold for the RCI to be considered pressed.

==== Advanced Config ====
Enable and configure various monitoring features.
