{"product_id":"woodbrass-ba820-20w-396383","title":"BA820 20W","description":"\u003ch3\u003eContexto histórico e posicionamento na linha\u003c\/h3\u003eConcebido pela Woodbrass para a prática diária, o BA820 se posiciona como um combo de estudo moderno e versátil. Seu formato de 20 W o coloca no coração da linha de amplificadores de treino: mais potente e mais \"sério\" que um mini-amp, ao mesmo tempo que permanece suficientemente compacto para uma mesa, um quarto ou um home studio.\u003cbr \/\u003e\u003ch3\u003ePara quem é este amplificador\u003c\/h3\u003eO BA820 é adequado tanto para baixistas iniciantes quanto para músicos experientes que procuram um amplificador de trabalho confiável. Ele se destaca em casa, nas aulas, na pré-produção ou em ensaios com volume moderado. Seu registro neutro e musical adapta-se ao pop, rock, funk, soul, jazz ou reggae, com a precisão necessária para trabalhar o groove e a articulação.\u003cbr \/\u003e\u003ch3\u003eFuncionalidades e novidades\u003c\/h3\u003eCom seus 20 W em classe D, o BA820 oferece um rendimento limpo e estável, mantendo-se leve. A seção de equalização de 4 bandas (grave, médio-baixo, médio-alto, agudo) proporciona um controle fino do espectro, útil para corrigir a acústica de um ambiente ou afinar o caráter dos seus microfones. Na parte prática, a entrada auxiliar em Jack 3,5 mm e a recepção de áudio sem fio permitem tocar sobre backtracks sem equipamento adicional, enquanto a saída para fone de ouvido em Jack 3,5 mm desliga automaticamente o alto-falante para um trabalho silencioso. A alimentação externa universal 100-240 V garante uso tranquilo em casa ou em deslocamentos.\u003cbr \/\u003e\u003ch3\u003eO timbre\u003c\/h3\u003eAmplificador a transistores com comportamento moderno, o BA820 oferece um som limpo claro, firme e definido, com graves amplos mas bem controlados pelo alto-falante de 6,5 polegadas. A dinâmica permanece responsiva em volumes baixos e médios, ideal para trabalhar a precisão da mão direita e as nuances. A equalização de 4 bandas permite adicionar corpo nos médios-baixos, clarear os médios-altos para destacar-se na mixagem, ou suavizar os agudos para um toque mais aveludado. Aceita sem dificuldade pedais de pré-amplificação, compressores ou efeitos na entrada.\u003cbr \/\u003e\n\n\u003ch2\u003eEspecificações
