{"product_id":"jbl-308-mkiii-438690","title":"308 MKIII","description":"\u003ch3\u003eUma referência de 8 polegadas da série JBL 3 MkII\u003c\/h3\u003e\u003cp\u003eA JBL 308P MkII integra a série 3 MkII, uma linha de monitores de campo próximo desenvolvida para oferecer ferramentas de mixagem confiáveis em home studios, salas de controle de produção e espaços modernos de criação. Esta versão MkII retoma os princípios acústicos desenvolvidos nos monitores profissionais de alto desempenho da marca, incluindo o guia de ondas Image Control, proveniente das séries JBL 7 e M2.\u003c\/p\u003e\u003cp\u003eEm comparação com as gerações anteriores, esta evolução aprimora a resposta dos transdutores, melhora a linearidade e introduz o ajuste \u003cstrong\u003eBoundary EQ\u003c\/strong\u003e. Ele ajuda a compensar o excesso de graves provocado por uma instalação muito próxima de uma parede, de um canto ou de uma superfície de trabalho. Um avanço concreto para manter decisões de mixagem coerentes em um estúdio sem tratamento acústico ou de dimensões reduzidas.\u003c\/p\u003e\u003ch3\u003eUm monitor de campo próximo para mixar, produzir e ouvir com perspectiva\u003c\/h3\u003e\u003cp\u003eCom seu alto-falante de graves de 203 mm, a JBL 308P MkII é especialmente adequada para produtores que buscam uma reprodução estendida na região mais grave do espectro sem recorrer sistematicamente a um subwoofer. Kick, baixo elétrico, sub-bass, sintetizadores e efeitos cinematográficos ganham mais definição, mantendo-se integrados ao equilíbrio geral da mixagem.\u003c\/p\u003e\u003cp\u003eEla encontrará naturalmente seu lugar em um home studio sério, uma sala de controle de pós-produção, uma instalação de composição ou um espaço de DJing que exija uma escuta analítica. Seu nível de pico de 112 dB SPL também permite trabalhar em um volume confortável em uma sala de tamanho médio, desde que seja respeitado o posicionamento em triângulo equilátero com o ponto de escuta.\u003c\/p\u003e\u003cp\u003eVendida individualmente, esta caixa acústica ativa deve ser associada a uma segunda 308P MkII para formar um sistema estéreo. Ela também pode integrar uma configuração imersiva ou multicanal graças à sua reprodução homogênea e à sua diretividade controlada.\u003c\/p\u003e\u003ch3\u003eUma reprodução ampla, ajustável e precisa\u003c\/h3\u003e\u003ch4\u003eGuia de ondas Image Control: um sweet spot mais amplo\u003c\/h4\u003e\u003cp\u003eO guia de ondas Image Control otimiza a dispersão do tweeter de domo macio de 25 mm. A imagem sonora permanece precisa, com um posicionamento mais definido das vozes, das reverberações e dos instrumentos panoramizados. Sua cobertura de 120 graus na horizontal e 90 graus na vertical amplia a área útil de escuta: uma vantagem significativa durante sessões longas, comparações de mixagens ou trabalhos a dois diante do console.\u003c\/p\u003e\u003ch4\u003eBi-amplificação Class D dedicada a cada faixa\u003c\/h4\u003e\u003cp\u003eA 308P MkII incorpora dois amplificadores Class D de 56 W, totalizando 112 W. O woofer e o tweeter contam, assim, com amplificação dedicada, proporcionando melhor controle dos transientes e uma reprodução mais responsiva. O filtro acústico Linkwitz-Riley de quarta ordem a 1.800 Hz garante uma transição coerente entre os dois alto-falantes.\u003c\/p\u003e\u003cp\u003eA resposta de frequência desce até 45 Hz na faixa de +\/- 3 dB, com uma extensão anunciada até 37 Hz a -10 dB. Essa base sólida permite controlar melhor a energia dos graves e identificar as ressonâncias que poderiam prejudicar a tradução da mixagem em outros sistemas de escuta.\u003c\/p\u003e\u003ch4\u003eCorreções práticas para o estúdio\u003c\/h4\u003e\u003cp\u003eO seletor \u003cstrong\u003eBoundary EQ\u003c\/strong\u003e atua nas baixas frequências em torno de 50 Hz, com três posições: 0 dB, -1,5 dB e -3 dB. Ele permite limitar o acúmulo de graves quando o monitor é colocado próximo a uma parede. O ajuste \u003cstrong\u003eHF Trim\u003c\/strong\u003e, disponível em -2 dB, 0 dB e +2 dB, ajusta o brilho de acordo com a acústica da sala ou com as preferências de escuta.\u003c\/p\u003e\u003cp\u003eA conectividade balanceada combina uma entrada XLR e uma entrada jack TRS de 6,35 mm. O seletor de sensibilidade +4 dBu ou -10 dBV facilita a integração da JBL 308P MkII tanto com equipamentos profissionais de estúdio quanto com dispositivos de áudio mais voltados ao público geral. Um controle de volume no painel traseiro completa o conjunto, permitindo ajustar com precisão o ganho de cada caixa acústica.\u003c\/p\u003e\n\n\u003ch2\u003eEspecificações
