The Ziegfeld Ballroom utilizes Harman sound and lights.

The Ziegfeld Theatre opened in 1969 as a single-screen movie theatre. The theatre was named in honor of the impresario Florenz Ziegfeld, Jr. Between 1969 and 2016, more world premieres of Hollywood blockbuster films were held at the Ziegfeld Theatre than any U.S. movie theatre outside of Los Angeles. Building on a rich history, the Ziegfeld Ballroom opened Fall 2017 as one of the most significant event properties in New York City.
The sound and lighting for the Ziegfeld Ballroom is an entirely Harman solution using JBL speakers all powered by Crown 4×3500 amplifiers. The lighting is Martin Professional.
