{"product_id":"bss-ar133-74809","title":"AR133","description":"\u003ch3\u003eA referência dos palcos ao vivo há anos\u003c\/h3\u003e \u003cp\u003eAclamada desde pequenas casas até os maiores palcos, a AR133 se consolidou como uma escolha segura para enviar sinais de instrumentos para uma mesa sem ruídos indesejados. Sua arquitetura com transformador e design cuidadoso fazem dela uma \u003cstrong\u003eDI\u003c\/strong\u003e estável e confiável, feita para uso intenso.\u003c\/p\u003e \u003ch3\u003ePara quem e para quais usos?\u003c\/h3\u003e \u003cp\u003eIdeal para técnicos de som, músicos e backliners, esta caixa DI se destaca em shows, ensaios e estúdio móvel. Ela converte de forma limpa os sinais de instrumentos e fontes de linha, limita os zumbidos causados por loops de terra e garante segurança nas trocas rápidas de instrumentos no palco.\u003c\/p\u003e \u003ch3\u003eFuncionalidades pensadas para o campo\u003c\/h3\u003e \u003cp\u003eA alimentação é inteligente: quando a mesa fornece os 48 V phantom, a AR133 os prioriza e o LED indica a presença da tensão. Caso contrário, a bateria de 9 V assume automaticamente e o LED pisca para alertar o usuário. Resultado: continuidade de serviço sem estresse.\u003c\/p\u003e \u003cp\u003eO transformador interno, totalmente blindado, assegura excelente rejeição a interferências eletromagnéticas e garante isolamento galvânico entre entrada e saída. O interruptor de corte de terra ajuda a eliminar problemas de \"loop de terra\" em configurações complexas.\u003c\/p\u003e \u003cp\u003eGraças às três sensibilidades de entrada (0, -20, -40 dB), você ajusta instantaneamente o nível à fonte. O interruptor de ativação permite desconectar um instrumento e conectar outro sem precisar \"mutar\" o canal na mesa, para trocas rápidas e limpas.\u003c\/p\u003e \u003cp\u003ePor fim, a construção mecânica com amortecedores de borracha limita a transmissão de vibrações do chão, prolonga a vida útil do equipamento e preserva a qualidade de áudio em condições reais de uso.\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) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:3;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eInstalável em rack\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eNão\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eTipo\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eACC71_type_boitier\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:4;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategoria\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eaccessoires_sonorisation_categorie_convertisseur_audio\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:8;--wb-lb:transparent;--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eSaída\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003esimétrica através de transformador (isolamento galvânico)\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eInterruptor de corte de massa\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003esim\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:9;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eResposta em frequência\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e30 Hz a 20 kHz, +0\/-1 dB\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eInterruptor de ativação\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003esim\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:3;--wb-r:10;--wb-lb:transparent;--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDistorção\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e\u0026lt;
