Descrição

TOA / M-864D é um mixer digital stereo, 4U rack, com 22 canais de entrada de áudio, sendo destas 8 entradas mono e 7 stereo, além de 6 canais de saída, incluindo 4 mono e 01 stereo (esta dedicada a gravação), e 4 canais bus.

Está equipado com funções de processamento digital de áudio, incluindo Controle Automático de Ressonância (ARC(*1)), Redutor de Microfonia (FBS), Função de Mute automático para as entradas stereo (AUTO MUTE ou Ducker) e Equalizador.

Pode-se executar compensação acústica avançada, sem ter que utilizar nenhum equipamento externo dedicado a esta tarefa. Equipado com vários botões de ajustes e 14 faders de volume,  o M-864D pode ser operado sem necessidade de utilizar um PC. No entanto, ele também pode ser operado via software através de um computador PC ou através de controle remoto opcional, via painel traseiro. Pode ser montado em um rack, ocupando 4 unidades. (*1)

A função Automatic Resonance Control cria automaticamente curvas de filtro para melhor a inteligibilidade sonora, medindo características acústicas do ambiente.
