SIPP and DECT bringing people together!
Wireless headphone parties, hyped throughout the festival world, just got a whole lot simpler thanks to a new DECT-based wireless audio system.
There is an increasing demand for quieter concerts, performances and events. Concerts have been conducted under this concept for many years. In 1999, The Flaming Lips played the South by Southwest festival in Austin, Texas. Dubbed the world’s first headphones concert, the band distributed mini FM radios to the audience and used an FM generator to transmit the music. But these early attempts were plagued with technical difficulties due to battery lifetimes and systems that were complicated to set up and use.
Now demand for sponsors to organize some kind of special with music and sound is gaining ground. Moreover the entertainment industry plans to produce more sustainable/green events that reduce noise pollution and the risk of hearing damage. Visitorsalsoliketobesurprisedandhave
more sources of music to choose from. The challenge is getting a large number of music channels at a festival and to ensure good reception for the headphones.
Wireless entertainment made simple
A simpler option is a new technology called Sound Input Per Person (SIPP.fm). Based on 1.9 GHZ DECT, this wireless audio system provides robust and uninterrupted digital audio reception for a very large numbers of receivers/headsets simultaneously. It can accommodate 8 music channels in areas up to 10 hectares, so is ideal for on-site use at events, concert halls, nightclubs and theme parks, although the architecture of this technology can go far beyond these figures.
Using1.9GHzDECTtechnologyhasmany
advantages. No interference, over 1 km range and many operating music channels that can be used in parallel. This is very difficult in the congested 2.4 GHz band. Hence, until now wireless headphone systems were using analog or proprietary digital solutions in the different ISM bands. These systems suffer from drop-outs and interference issues, especially when the
systems scale up.
The new technology is
