如果使用铲型接线片,请按照制造商的规定将其连接到电线上。逆时针转动顶帽将其松开,直至间隙足以使铲型接线 片定位在端子接线柱周围。将铲型接线片置于接线柱周围并用手顺时针转动顶帽,以将接线片夹紧。请勿使用工具来 拧紧。重复操作进行其他扬声器连接。

如果使用单或双橡胶插头,请按照制造商的规定将其连接到电线上。顺时针转动端子的顶帽以确保其完全固定。请勿 使用工具来拧紧。将橡胶插头插入顶帽中心所提供的孔中。重复操作进行其他扬声器连接。

有关将扬声器电线连接到接收机或放大器的信息,请参阅接收机或放大器的用户手册。

重要信息!

为确保最佳性能,进行扬声器连接时请注意极性。端子罩上有 + - 符号,顶帽有红色环表示 +,有黑色环表示 -–。将放大器或接收机背面的各 + 端子分别连接至各扬声器的 +(红色)端子。按相同方法连接 -(黑色)端子。如果 连接不正确,则可能导致低音响应和成像不良。此外,为避免短路以免损坏设备,请小心不要让电线的末端接触任何 其他电线的末端。

超低音扬声器

为获得最佳效果,请将超低音扬声器安置在与前置扬声器相同的墙壁上(或角落里)。原则上,交叉点越低,超低音 扬声器离前置扬声器的距离就能越大,但是,声音通常在超低音扬声器位于前置扬声器周围 12 英尺 (3.5m) 以内时 达到最佳。超低音扬声器所输出低音的感知电平,会因房间位置的不同而有明显的差异。靠墙放置时,在墙角放置会 强化低音输出电平,提供最高感知输出电平。远离墙壁放置会产生感知电平过小的低音。无论房间内低音感知电平如 何,总能通过内置音量控制或者前置放大器或接收机的电平控制来调整超低音扬声器的电平。任何时候移动超低音扬 声器时,请务必重新检查输出电平和 EQ 设置(若有)。由于人耳定位低频的能力较弱,低音仍会好像是从前置扬声 器发出的。实践是最有效的方法,但房间的大多数位置均适合放置。

重要信息:请勿将超低音扬声器放置在后面板可能会和垂帘或家具接触的位置。放大器面板还用于散热,必须至少保 持 3 英寸 (76mm) 的间隙以避免过热。

注意:除非拔下插头或使用位于后面板的电源开关切换至静音位置,否则始终会向 MSubwoofer 电子装备供电。自动 打开电路只会激活或关闭功率放大器。请确保在进行连接时拔下 MSubwoofer 和前置放大器/接收机的插头。

电源:当插上 MSubwoofer 电源插头时,请务必使用墙壁电源插座或专用电源插座。某些接收机会提供开关插座。请 勿使用此类插座。这些板载电源插座无法提供功率放大器(如 MSubwoofer 中的)所必需的电流量或适当的绝缘。

线路电平或 LFE:大多数系统使用线路电平输入或 LFE 输入。这些输入接受来自前置放大器/接收机超低音扬声器输出 的线路电平信号。接收机手册中会指示最合适采用哪种输入。
