To make a solid sound environment, the 5.1ch surround sound system was adopted.
The speakers used for the exhibition were ME-GEITHAIN(*1), the highest quality in the world. This was the first known use in Japan of these remarkable five speakers, simultaneously.
The sound data was stored in one of the Client PC of the control system. After that, the data was distributed to each ME speaker by the YAMAHA O2R mixer (*2).
MartinAudio S218(*3) was used for woofers.
