Although stadium developers added additional seats, with which the number of places has increased to just over 34.000, The restrictions that the country has make them necessary as the official headquarters of the baseball competitions of the Olympic Games.

In this renewal, The audio system has focused on the multinational's speakers RCF, which in turn serves to public address and voice alarm (PAY) in case of any incident.

The main systems, which consist of two four TTL 33-WP arrays each one, They are placed on six light poles around the stadium (with a total of 48 speakers). The sound bars have been fixed to custom-built titanium mounts.

The TTL 33-WP and other RCF speakers were essential to maintaining sound clarity, without losing the volume of the lower part of the spectrum, contrary to what happens when the volume is lost in the low frequency to prioritize clarity, something often seen in outdoor facilities”.

It is perfect for the size and shape of the installation thanks to its innovative design, the ease of speaker adjustment, orientation and balance of levels. In particular, sound coming from the opposite side of the field is well controlled. Currently there are many sports facilities with arrays installed linear, and here the sound is very well controlled, which contributes to improving its clarity and quality”.
