Background music is distributed by using the Audio Program feature of the ICX-AlphaCom. By default this feature is using the HD Voice codec G.722.
In installations where an even better audio quality for background music distribution over the PA system is required, it is possible to use the HD Audio codec PCM L16/48kHz.
The following devices support audio input feed using the PCM L16/48kHz codec:
- ENA Amplifier
- TKIE-2 kit
The following devices can play (listen to) audio in PCM L16/48kHz format:
- ENA Amplifiers (ENA2200, ENA2400-AC, ENA2400-DC and ENA-2100)
- Turbine kits (TKIE-1, TKIE-2 and TKIS-2)
- IP Speakers (ELSII-10H and ELSIR-10C)

Contents
Requirements
Software
HD Audio is supported from:
- ICX-AlphaCom: 1.0.3.0
- AlphaCom XE: 12.5.3.1
- Intercom device: 4.9.3.0 (recommended: 8.0.3.0 or higher)
License:
- HD Audio for background music distribution requires a High bandwidth audio license. It is sufficient with one HD Audio license per ICX-AlphaCom server.
- If the Audio Input source is the Line Input of the ENA Amplifier, one ENA Amplifier Channel License is required
- To install the license, log on to the web interface of the ICX-AlphaCom server, and select System Configuration > Licensing.
Audio Source Configuration
TKIE-2 as Audio Source
Log in to the web interface of the TKIE kit, and enable Advanced Configuration in the top right corner of the web interface.
Enable Line In:
To use the TKIE-kit as Audio Program source, enable Line In. A reboot of the TKIE kit is required for the change to take effect:
Disable AGC (Automatic Gain Control):
Set Audio Engine Mode = HD-Audio:
ENA Amplifier as Audio Source
The Line In on an ENA amplifier can be used as Audio Program Source.
- Log In to the amplifier
- In Main > Main Settings enter a directory number to use for the Line Input:
Audio Receiver Configuration
In the devices that should play HD Audio (e.g. ENA Amplifiers, Turbine kits or IP Speakers), the Audio Engine Mode must be set to HD-Audio:
Configuration of ICX-AlphaCom server
The "HD Audio" is transmitted from the Audio Source as Multicast data in the network. The ICX-AlphaCom must be configured to use Multicast for group audio.
In AlphaPro, Exchange & System > System > VoIP tab, enable Multicast:
The Line Input channel of the ENA Amplifier (or the TKIE-2 kit) must register to a directory number in the ICX-AlphaCom server.
In AlphaPro, Users & Stations, enter a directory number for the Line Input and set the Noise Reduction to 0:
Create a feature code to become an Audio Source. From AlphaPro Directory & Features, press Insert and create a new directory number:
- Feature 118 - Program Source
- ID (Parameter 1) = Program channel 1-70
- Parameter 2 = Group index 1- 255. Choose a group which is not in use. Important: At least one station must be included in this "dummy" group.
- Parameter 3 = 10 (PCM L16/48kHz codec)
The example below shows how to add directory number 6801 as the code to become the source of Audio Program #1.
Include at least one station/user in the group defined in parameter 2 above (in this example group 100):
|
|
The station added to the group doesn't have to be a real station, simply pick any unused station. Do not add an IP Dummy to the group, as it will prohibit the HD Audio setup. |
A station/device dialing feature 118 becomes the program feeder. Add an event that sets the Audio Program Source as source for program feed. Use the event 13 (Faulty Station), When Change To = OFF, and action: $DD L%1.dir L6801.
The Audio Program Source must be allowed access to feature 118. To avoid any other station/device dialing the directory number for the feature, it is advisable to define a separate COS for this feature. Add feature 118 to this Class of Service (CoS #2 in the example below).
Assign the Audio Program Source to the Class of Service:
Reboot the ICX-AlphaCom:
After having updated the ICX-AlphaCom (SendAll), the ICX-AlphaCom needs to be rebooted in order to trigger the event that forces the Audio Program Source to start feeding audio.
