使用 LFE 端口将超低音扬声器连接到数字家庭影院系统

多声道家庭影院系统专门使用一个声道(“.1”)再现数字编码音轨中包含的低频效果 (LFE)(如爆炸声和雷声)。

通过此方法,接收机的放大器无需再现可能导致接收机声音失真的超低音信号。某些情况下,也可能取决于接收机 的若干其他设置。建议您参阅接收机手册,以获得该领域的进一步协助。

如图所示,使用音频 RCA 电缆(不附带)将数字接收机的 LFE/超低音输出连接到超低音扬声器。 将另一端连接到线路电平/LFE 输入端口。

如果系统中的前置放大器/接收机没有超低音或 LFE 输出,可将 MSubwoofer 超低音扬声器连接到前置放大器/可变 输出。

使用立体声 RCA 电缆(不附带)将前置放大器输出连接到“L”“R”线路电平输入。注:对于没有多路前置放 大器输出的前置放大器,可能需要分路器。
