Yamaha Corporation of America, Commercial Audio Systems Division, has announced the first U.S. installation of their proprietary Active Field Control (AFC) system.

After several installs in Japan, the company installed the AFC in the Piano Salon of Yamaha Artist Services Inc., a 15,000 square-foot facility located in the Elizabeth Arden Building in New York City, which offers a variety of services and technology to Yamaha artists. The AFC system will help tune the Piano Salon’s acoustics, reportedly transforming the room into a reverberant space for music.

The Yamaha AFC system is based on A-SF (Assistance of Sound Field) technology, which utilizes a feedback loop to modify a room’s existing acoustic properties without physical modification. AFC not only changes auditory impressions of architectural sound—such as reverberation, loudness and the perception of spaciousness—but also enhances early reflections to improve the sound quality in undesirable acoustic conditions, such as under-balcony or stage areas.

AFC can add reflected sounds by extending reverb time through time variant FIR (Finite Impulse Response) filters and increasing the gain of the FIR filters—uniformly distributing enhanced reflected sounds—and can intensify the feeling of spaciousness by adding lateral reflected sounds.

A complete Yamaha turnkey system, AFC components include the Yamaha AD8HR A/D Converter, AFC1 AFC Processor, DA824 D/A Converter, Yamaha XM and PC Series amplifiers, new proprietary AFC speakers and a controller.
