{"product_id":"neumann-u87-ai-black-159199","title":"U87 Ai Preto","description":"\u003ch3\u003eUma lenda nascida em 1967, pilar da linha Neumann\u003c\/h3\u003e\u003cp\u003eIntroduzido em 1967, o U 87 impôs-se como um padrão da gravação profissional, a ponto de se tornar uma imagem mental do \"microfone de estúdio\": silhueta esguia, ampla grade emblemática, e uma assinatura sonora onipresente em décadas de produções. A versão \u003cstrong\u003eU 87 Ai\u003c\/strong\u003e prolonga essa tradição com uma abordagem fiel ao DNA Neumann: um design de cápsula de duplo diafragma herdado da filosofia dos grandes modelos da marca, associado a uma eletrônica moderna, estável e pensada para os ambientes de estúdio atuais.\u003c\/p\u003e\u003ch3\u003eUm microfone pensado para a voz... e muito mais\u003c\/h3\u003e\u003cp\u003eO Neumann U 87 Ai é frequentemente escolhido como \u003cstrong\u003emicrofone vocal principal\u003c\/strong\u003e graças à sua reprodução natural e presença marcada nos médios, ideal para posicionar uma voz no centro da mixagem sem agressividade. Ele também se destaca em \u003cstrong\u003evoz falada\u003c\/strong\u003e (voice-over, dublagem, podcast de alta qualidade, audiobook) quando se busca articulação, profundidade e coerência, com uma textura imediatamente \"profissional\".\u003c\/p\u003e\u003cp\u003eSua versatilidade vai muito além: violão acústico, overheads de bateria, amplificadores de guitarra e baixo, captações clássicas em microfone spot (por exemplo, violoncelo), e até piano em par estéreo. As três direcionalidades permitem otimizar a captação conforme o ambiente, a fonte e a quantidade de ambiência desejada, mantendo um timbre estável e equilibrado.\u003c\/p\u003e\u003ch3\u003eUm design clássico, a serviço de uma assinatura sonora atemporal\u003c\/h3\u003e\u003ch4\u003eCápsula de duplo diafragma e transdutor de gradiente de pressão\u003c\/h4\u003e\u003cp\u003eO U 87 Ai é um \u003cstrong\u003emicrofone condensador de grande diafragma\u003c\/strong\u003e baseado em um transdutor de gradiente de pressão e uma cápsula de duplo diafragma. Essa arquitetura contribui para sua capacidade de combinar \u003cstrong\u003eresposta de frequência controlada\u003c\/strong\u003e e \u003cstrong\u003ecaráter\u003c\/strong\u003e: uma reprodução precisa, mas nunca clínica, com aquele \"algo mais\" que valoriza a fonte e facilita o posicionamento na mixagem.\u003c\/p\u003e\u003ch4\u003eEletrônica FET, caminho de sinal mínimo e saída por transformador\u003c\/h4\u003e\u003cp\u003eO amplificador de cabeça baseia-se em um \u003cstrong\u003ecircuito FET\u003c\/strong\u003e com caminho de sinal reduzido, e uma \u003cstrong\u003esaída balanceada por transformador\u003c\/strong\u003e. Essa abordagem visa uma transmissão robusta do sinal, bom rejeitamento de interferências em ambiente de estúdio, e uma estabilidade que contribuiu amplamente para a reputação do modelo em sessões exigentes.\u003c\/p\u003e\u003ch4\u003eControle da dinâmica e gestão de fontes fortes\u003c\/h4\u003e\u003cp\u003eCom um \u003cstrong\u003eSPL máximo elevado\u003c\/strong\u003e e um \u003cstrong\u003epré-atenuador\u003c\/strong\u003e que permite suportar níveis maiores, o U 87 Ai também pode ser usado em fontes potentes (amplificadores, percussão, captações próximas), mantendo uma reprodução detalhada dos médios. Associado a um bom pré-amplificador de microfone, torna-se uma ferramenta confiável, capaz de transitar de uma voz intimista para uma captação mais energética sem perder coerência.\u003c\/p\u003e\n\n\u003ch2\u003eEspecificações técnicas\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
