Yamaha is highlighting an upcoming upgrade to its Active Field Control (AFC) acoustic conditioning system at InfoComm 2019. The new AFC4 (fourth generation) system features significant upgrades in digital signal processing (DSP) and hardware. “When combined with optimally placed microphones and loudspeakers, AFC4 operators can greatly enhance or create any space, from a cathedral to an outdoor or roofless venue, with an organic-sounding acoustical environment,” according to the announcement.
First released in 1985, Active Field Control systems augment the architectural design of facilities such as performance arts venues, houses of worship, theaters and concert halls, while maintaining the natural sonic characteristics of a space. The technology is designed to provide a cost-effective and flexible alternative to expensive and time-consuming physical renovations, enabling venue operators to offer a wide range of sonic applications at the push of a button.
The new AFC4 system’s expanded DSP power and connectivity are designed to improve sound quality and versatility. The processor's sampling rate, fixed FIR taps, FIR presets and configurable FIR tap settings have all been upgraded, and the system is now equipped with a FIR EQ in favor of the previous AFC3 version’s parametric EQ.
Combined with greater connectivity options — 32 mic inputs and 96 output channels — this DSP upgrade gives users creative flexibility to realize a broader range of sonic “experiences,” from subtle and nuanced to dramatic and extreme.
“With our collective knowledge in musical instruments, professional audio products and performance space design, Yamaha has unique insights into the nature and behavior of sound creation and acoustics,” says Joe Rimstidt, systems design engineer, Yamaha Professional Audio department. “The new AFC4 system incorporates that vast expertise and adds enhanced performance, sound quality and flexibility making it even easier to create incredibly natural and immersive acoustic experiences for audience members and performers.”
The new Active Field Control (fourth generation) system is planned for availability in the fall of 2019. InfoComm attendees can experience this technology and all Yamaha commercial audio products in the Yamaha booth #6461 and demo room (W224D) in the Orange County Convention Center.
