2N® Helios IP - How to receive/send multicast stream from/to 2N® IP Audio Manager

Sending or receiving multicast stream from/to 2N® Helios IP intercom is a feature that can be used for emergency calls or just for any announcement that will be sent from/to 2N® IP Audio Manager. How to set both scenarios can be found in description below.

How to receive multicast stream from 2N® IP Audio Manager

If you want to set 2N® Helios IP as a audio destination for 2N® IP Audio Manager, you must connect it as a RTP destination.

2N® IP Audio Manager setting

Open 2N® IP Audio Control Panel and go to section Destinations & Zones. Here click on right mouse button and choose the option "Create RTP destination".

Then choose created RTP destination and specify IP Address and Port on which your 2N® Helios IP will be  listening.

As a last step in 2N® IP Audio Manager settings go to Sessions, create a new session and assign previously created RTP destination as the destination for audio broadcasting.

2N® Helios IP setting

Configuration on 2N® Helios IP side is very easy, all you need to do is to go to the section Advanced Settings -> Multicast and activate the multicast receiving. In Address and Port parameters specify the same IP address and port which you added to 2N® IP Audio Control Panel


How to send multicast stream to 2N® IP Audio Manager

If you want to use 2N® Helios IP for making announcements to all speakers connected to 2N® IP Audio Manager, you must connect it as new RTP source.

2N® IP Audio Manager setting

Open 2N® IP Audio Control Panel and go to section Audio Sources. Here create new RTP source and specify for it Port and IP address on which you will be sending announcements.

When the RTP source is created, go to section Sessions and create a new session. Here add a new RTP destination as audio source, specify units or zones to which you want to broadcast and the activate the session.

2N® Helios IP setting

For setting the paging function on 2N® Helios IP you have to use Automation feature.

The settings below mean that if any user presses the quick dial button 5 on the 2N® Helios IP intercom (for this settings you need to have the intercom with 6 buttons), then the user´s sound is sent as a multicast request to all other devices. This sound takes 2 seconds. After that period of time you can start talking and 2N® Helios IP will stream this multicast traffic to 2N® IP Audio Manager. If you want to stop multicast streaming, you just press the quick dial button 5 again.

Here are parameters used in picture above:








Note: All commands used in the Automation section are deeply described in our 2N® Helios IP Automation manual where you can find also some examples. This manual is available on our web pages:
