two sites straddling Biscayne Boulevard connected by a pedestrian bridge. Acoustics were designed by Russell Johnson of Artec Consultants company. He also worked on the Meyerson Symphony Center in Dallas. There are three main venues all of which can be rented for event space by the public: The Sanford and Dolores Ziff Ballet Opera House seats 2,400. The John S. and James L. Knight Concert Hall seats 2,200. Its stage extends into the audience and there is seating behind the stage for 200 additional spectators or a chorus. The orchestra level can be transformed into a "Grand Ballroom" with a festival floor configuration for dining and dancing for up to 850 people. The floor is installed over the seats. Carnival Studio Theater is a flexible black-box space designed for up to 300 seats. In addition, there are two smaller multi-purpose venues: The Peacock Rehearsal Studio holds 270 people. Parker and Vann Thomson Plaza for the Arts is an outdoor social and performance space linking the two main houses across Biscayne Blvd. Events and performances Programmatic series include Jazz Roots, the Knight Masterworks Season - Ziff Classical Music Series and Ziff Dance Series, Theater Up Close, Live At Knight, Flamenco Festival, Miami Light Projects Here and Now Festival, and City Theatre's Yearly Short Play Festival. For research purpose, the place is quite suitable. So, the people who're interested in viewing such artifacts, can visit here using airways and at affordable prices. The center hosts approximately 400 performances and events each year, which attract an average of 450,000 people to Miami's urban core. More than 85% of the performances at the center are presented by the center. Presidential Debates The center was the site of the first Democratic primary debate of the 2020 presidential campaign, held on June 26–27, 2019, and was due to host the second of three general election debates in October 2020, but this did not go ahead. President Donald Trump had contracted COVID-19 in the week before the debate and was recovering from it; for reasons of safety, the Commission on Presidential Debates proposed a virtual debate instead but Trump refused to participate. Instead, NBC News held a town-hall style event with President Trump alone, moderated by Savannah Guthrie, within the outdoor portico of the neighbouring Pérez Art Museum; the Democratic nominee, former Vice-President Joe Biden, participated in a simultaneous town-hall debate with George Stephanopoulos for ABC News
