AFC3 Descontinuado
Active Field Control
For over 125 years YAMAHA craftsmen have created some of the world’s finest musical instruments. Superior sound quality has always been the driving force behind all of Yamaha's efforts. Whether manufacturing instruments, developing state-of-the-art audio technologies or designing performance halls and theatres, Yamaha is always seeking new ways to deliver the best possible listening experience.
Implementado pela primeira vez em 1985, o Controlo Ativo de Espaço (AFC) é um sistema acústico de condicionamento concebido para ajustar e potenciar as características arquiteturais acústicas de um espaço físico – salas de exposição, igrejas e templos de oração, teatros e salas de concerto – ao mesmo tempo que procura assegurar as características sonoras naturais desse mesmo espaço.
O AFC3 apresenta a terceira geração de inovação nos sistemas de Controlo Ativo de Espaço (AFC) da Yamaha, uma marca de referência na indústria áudio.
With increasing pressure for facilities to become more multi-purpose and accommodate a wider range of applications AFC3 provides a cost-effective alternative to mechanical means of modifying room acoustics. A truly scalable solution which can be installed in a wide range of venues AFC3 makes it possible to hold classical concerts in a very large hall without a sound reinforcement system, to accommodate an organ in a small church, or to enhance crowd response in a stadium. Reverberation changes can be made at the push of a button, allowing the performance environment to be adjusted almost instantly. In addition AFC3 is able to deliver the same high-quality sonic experience to every performer and member of the audience.
Yamaha AFC systems are currently installed in over 80 facilities in the U.S. and Japan, and now with the release of AFC3, a much wider range of facilities worldwide will now have access to the best acoustic enhancement system available today.
Informação do Produto
O que é o AFC?
Active Field Control is an acoustic enhancement system that is used to improve or enhance the architectural acoustic characteristics of a room and optimize reverberation while preserving that room's natural acoustic ‘signature’. Yamaha DSP technology enables us to realize this system with a small set of core devices.
O AFC ajusta as condições acústicas através de um sistema de feedback acústico que torna o AFC diferente e superior a outras técnicas empregues no que diz respeito a reverberação digital para simular as características de uma sala ou espaço.
Unidade Central do AFC3
A unidade central do AFC3 foi concebida com base no reconhecido processador de mistura digital DME64N da Yamaha. A versão melhorada deste processador contida no AFC3 inclui os misturadores de matriz típicos, linhas de delay, equalizadores paramétricos, funcionalidades de routing, assim como componente especializados de DSP desenvolvidos especificamente para aplicações do AFC. Enquanto um slot para cartão do processador AFC3 recebe um cartão dedicado ao processamento das funcionalidades FIR, os restantes três slots para cartões MY fornecem os primeiros 22 canais de saída do sistema de AFC. Podem ser adicionadas unidades complementares ao AFC3, em ligação à unidade central, para obter mais canais de saída.
Cartão FIR do AFC
O cartão FIR- AFC é usado para trabalhar a densidade elevada do processamento FIR que antigamente não era possível. Os sistemas AFC3 com o cartão FIR-AFC são capazes de trabalhar com conjuntos de filtros FIR que contenham 125 vezes mais controladores do que o existente nos anteriores sistema AFC. Esta melhoria, no tamanho e densidade dos conjuntos de filtros FIR existentes, possibilita atingir aumentos mais prolongados na reverberação natural de uma sala, sem recorrer a efeitos de som fabricados.
Recommended Products
Surface Mount Speakers: VXS Serries
From Yamaha’s Commercial Installation Solutions line of products, the VXS8 is a full range, 2-way surface mount speaker compatible for AFC installations. Based on an 8” low frequency driver with 1” dome tweeter, the VXS8’s multi-tap transformer includes a low impedance tap for 8Ω operation suitable for AFC projects. The VXS8 comes in black or white and includes a mounting bracket with adjustable pan and tilt for safe, easy installation from a wall or ceiling and is IP45 rated for outdoor applications. Great sound and flexible mounting hardware make the VXS8 an excellent option for surface mount speaker applications in AFC projects.
The VXS10S surface mounted subwoofer is equipped with a 10” dual voice coil driver to provide extended low frequency response in appropriate AFC applications. Available in black or white, its relatively compact size and included wall mounting bracket facilitate discreet placement as part of an AFC project when subwoofers are required.
Ceiling Speakers: VXC Series
From Yamaha’s Commercial Installation Solutions line of products, the VXC8 is a full range, 2-way ceiling mount speaker applicable for AFC installations. Based on an 8” low frequency driver with 1” dome tweeter, the VXC8’s multi-tap transformer includes a low impedance tap for 8Ω operation suitable for AFC projects. The VXC speakers are self-enclosed so a separate back box is not required. The VXS8 comes in black or white and includes a folding mounting ring to facilitate mounting from below the ceiling when access is limited. High performance and fast, simple installation make the VXC8 a great alternative for ceiling mount speaker placements in AFC installations.
Power Amplifiers: XMV Series
Os amplificadores de potência multi-canal da Série XMV aliam a eficiência da Classe D a características especificamente concebidas para beneficiar a instalação comercial dos sistemas de som. Esta Série é composta por 4 modelos diferentes, com capacidades de potência variáveis e conetividade de entrada/saída flexível, a fim de se adaptarem a uma vasta gama de ambientes de instalação.
S8AFC and S8AFC-D (*distributed in US only)
The S8AFC has a wide dispersion characteristic so the loop the feedback process works effectively and the listener cannot localize to the sound from the enhancement speakers. The specification of the speaker is effective for "natural changes" of the AFC system.
The S8AFC-D is an 8”, coaxial, two-way loudspeaker with built-in crossover network and push-button terminals. The S8AFC-D is intended to be mounted within a standard back can with an internal volume of ~1 ft3 for ceiling mount applications.
The S8AFC is Yamaha’s speaker enclosure incorporating this same 8”, coaxial two-way driver. The enclosure is black and includes mounting points to facilitate use of standard “U”-brackets from manufacturers such as Allen products for mounting.
The S8AFC can be used for mounting positions on walls, ceiling surfaces, or suspended from ceilings in positions where a conventional back can / ceiling speaker type mounting is not practical.
