Electro-acoustic technologies including Y-SFG and AFC for performing multi-contents in cinema complex - An example of United Cinemas TOYOSU

摘要

This paper reports the electro-acoustic cinema systems for performing multi contents in a cinema complex. In order to expand the feasibility of a cinema complex, several kinds of unique systems have been installed in the theater at the United Cinemas TOYOSU including the Y-SFG (Yamaha Sound Field Generation) and AFC (Active Field Control) systems. The Y-SFG system can reproduce realistic sound fields in the movie theater for live performances by the BS or CS broadcast programs. And the AFC system enables classical music concerts even in the acoustically dead room by enhancing its acoustical conditions like reverberation time. Also many kinds of other performances such as lectures or pop music concerts are available using the portable SR systems.
