Nexo and Yamaha tackle Toyota stadium upgrade


In preparation for the 2019 Rugby World Cup in Japan, the Toyota Stadium underwent an upgrade of its sound system with the use of products from Nexo and Yamaha. The installation was done by M&H Laboratory with assistance from Yamaha Sound Systems (YSS) and Nexo Engineering Support team.

The upgrade took place in several locations throughout the stadium. The system primarily consisted of Nexo’s high-spec GEO S12-ST line array modules, which were installed among the steel beams of the stadium structure. In the main and back stands, six modules of identical arrays were all placed near the edges of the large roof. Three module arrays are directed at the front row of the seats while additional sets of arrays were placed behind the seats. At several locations in the stadium, Nexo’s PS15-R2 and PS10-R2 cabinets were used as point sources. For auxiliary use, 48 PS10-R2 speakers were set up on the balcony edge round the perimeter.

HOR Masahiro Hori, sound operator for the Toyota Stadium, said: ‘I can clearly feel the difference between the previous speakers and the Nexo speakers. It feels like the Nexo speakers are never strained for sound. We also thoroughly corrected the level and time alignment, but the sound has much greater clarity than before. I also think a big improvement point is how we reduced the echo through appropriate adjustments.’

The Nexo equipment including the line array and point source loudspeakers was supplied by Yamaha Sound System, which also delivered a Yamaha CL5 digital console for the main mixer in the stadium’s operation room.

‘The Nexo speakers have higher efficiency than the previous ones, so we can output louder sound than before,’ commented Yoshiteru Mimura, president of M&H Laboratory. ‘Something that is important in this kind of facility is durability. Speakers in this kind of facility often break due to exposure to wind and rain. With the new Nexo system, we are able to achieve theatre-class high sound quality even in severe conditions.’
