2N® Net Audio Decoder

We’re Transforming a PC Into a Central Broadcasting System

2N® NetSpeaker has become 2N® Net Audio Decoder.

The 2N® Net Audio Decoder is an IP audio system that enables acoustic communication or other audio stream to be played from a given PC in a LAN/WAN network. For audio transmission over IP all you need to do is connect a standard speaker or amplifier to the 2N® Net Audio Decoder, thus creating a virtual central broadcasting system. This allows for any audio to be played with the options to create separate zones with different communication content. A use for this solution is found, for instance, in schools, shopping centres, office buildings, at train stations, in athletic, cultural or health facilities and in many other public spaces.

Customer references:

The original technology did not allow us to connect PBX to the old audio system. The sound quality did not match our requirements. We sought to find out a technology that would allow us modernization and integration with the IP world.

Juan Valdivia, IT manager, Quinta Normal

Customer references:

We contacted ITM-Components with a brief to supply equipment that would enable us to broadcast messages and background music around the Park which was controlled from a central location. The 2N system we agreed upon has achieved exactly what we asked for and we are extremely pleased with the result. Throughout the entire project we have received excellent service from ITM-Components.

Darren Chorley, Operations Director

Customer references:

We were looking for IP based audio solution that would be modular, flexible and could bring us wide adjustment options. With 2N IP audio we have met all of our requirements. We were also pleased with the minimum lead time from design to startup.

Rakesh Sarangi, Assistant General Manager – Electronics Tata Motors
