serviço ou assistencia tecnica

Se tiver alguma dificuldade depois de seguir as instruções de instalação, verifique as conexões dos cabos. Confirme se o equipamento eletrônico está funcionando corretamente ligando outro alto-falante na saída do alto-falante. Por exemplo, se nenhum som for reproduzido pelo alto-falante do canal esquerdo, conecte o alto-falante do canal direito à saída esquerda. Se continuar a não ouvir som algum daquele lado, o problema é no amplificador ou no aparelho eletrônico de origem. Caso isole o problema ao altofalante, entre em contato com o revendedor Polk onde o adquiriu. Os revendedores autorizados Polk são a melhor fonte de orientação e ajuda. O Departamento de Atendimento ao Cliente da Polk está disponível de segunda a sexta-feira, das 9:00 às 17:30 hs (horário de Nova York), pelo número +1-800-377-7655 (apenas EUA e Canadá; ligações de outros países devem ser feitas para +1-410-358-3600). Entre em contato conosco caso tenha alguma dúvida sobre o sistema.

1201, 1240DVC specifications

Polk Audio, a renowned name in the realm of audio technology, has made significant strides with its impressive subwoofers, particularly the Polk Audio 1201 and 1240DVC models. These subwoofers are engineered to deliver deep, powerful bass, enriching any audio experience, whether it’s for music, movies, or gaming.
