Typical music signals are characterized by crest factors, the ratio of peak signal power to average signal power, of 12dB or more. To avoid audible distortion due to clipping of peak signals, the gain of the DAC channel must be adjusted to prevent hard clipping of peak signals. As a result, during nominal periods, the applied gain is low, causing the perception that the signal is not loud enough. To overcome this problem, the DRC continuously monitors the output of the DAC Digital Volume control to detect its power level with regard to 0dBFS. When the power level is low, it increases the input signal gain to make it sound louder. At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard clipping. The resulting sound can be more pleasing to the ear as well as sounding louder during nominal periods. | Typical music signals are characterized by crest factors, the ratio of peak signal power to average signal power, of 12dB or more.

This article describes the configuration required for a Exigo Network Amplifier (ENA) 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.
Contents
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 ENA Amplifier Channel License is required per amplifier channel or audio in channel.
- For example, if Channel 1, Channel 2 and Audio In all have their own directory numbers, then 3 ENA Amplifier Channel License are required
- To enable the use of Background Music at 48 kHz PCM, a High bandwidth audio license is required. It is sufficient with one HD Audio license per ICX-AlphaCom server.
To install the license, 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
The amplifier web interface
Station Main tab
Station Information
- Log In to the amplifier
- The Station Information page will now be displayed, showing the amplifier 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 ICX-Alphacom radio-button.
Registration Settings:
- ICX-AlphaCom IP-address: Enter the IP address of the ICX-AlphaCom server to which the amplifier is to be registered
The amplifier can be assigned up to three separate directory numbers: Loudspeaker Channel 1, Loudspeaker Channel 2 and Audio Input. The directory number(s) must also be defined in the ICX-AlphaCom server.
- CH1 Out Directory Number: The first registered channel. This channel only supports audio output to CH1 amplifier.
- CH2 Out Directory Number: The second registered channel. This channel will output audio to CH2 amplifier.
- 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)
- - 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.
Station Administration tab
Reboot
- Reboot system: Perform a full Linux reboot. No configuration is lost
- Reboot main application: Perform a restart of the intercom application. No configuration is lost
- Factory reset: Set all parameters to Factory Default values. The amplifier will get static IP Address 169.254.1.100.
- Factory reset with DHCP: Set all parameters to Factory Default values. The amplifier will get IP Address from DHCP server. If no DHCP server in the network, it will get a random 169.254.x.x IP address.
- Clear local ZAP profile: For special purpose
- Delete ZAP data.lua: For special purpose
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.

Advanced ICX-AlphaCom tab
Audio
In Advanced ICX-Alphacom > Audio Dynamic Range Compression can be enabled.
Typical music signals are characterized by crest factors, the ratio of peak signal power to average signal power, of 12dB or more. To avoid audible distortion due to clipping of peak signals, the gain of the DAC channel must be adjusted to prevent hard clipping of peak signals. As a result, during nominal periods, the applied gain is low, causing the perception that the signal is not loud enough. To overcome this problem, the DRC continuously monitors the output of the DAC Digital Volume control to detect its power level with regard to 0dBFS. When the power level is low, it increases the input signal gain to make it sound louder. At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard clipping. The resulting sound can be more pleasing to the ear as well as sounding louder during nominal periods.
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.

RCO/RCI Config
There are 6 Control Outputs (RCO) and 6 Control Inputs (RCI) available. (On the ENA2100-AC amplifier there are 2 RCOs and 2 RCIs).
Configuration of the outputs and inputs is done from AlphaPro:
- The Control Output must be mapped to a Logical RCO. The operation of the logical RCOs is configured in the Event Handler window.
- The Control Input is configured in the RCI table in AlphaPro
Monitoring options
The ENA amplifier offers monitoring of the outputs and the inputs:
- RCOs
- RCO Monitoring alerts when the signal on the contacts are outside the configured legal values.
- 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".
- RCIs
- RCI Config allows configuring the thresholds for when the RCI triggers. An RCI has an open voltage of 10V across the terminals. A resistor network is needed to ensure that RCI's can be monitored properly.
- 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.
- Monitor RCI enables monitoring of RCI.
