尊敬的 HECO用户,
首先诚挚感谢您选购了 HECO 产品。我方在此向您表示衷心的祝贺。您选择明智,现在拥有
了一件举世皆认之精品。
在使用您的音箱之前,请您先认真阅读下列各项说明。

您需要用专业商店出售的喇叭专用电线来连接音箱。为了避免音质损失,在使用 3 m 以内
的电 线时,我们建议电线截面至少为 2,5mm²,在使用长于 3 m的电线时,截面应至少为
4 mm²。
接线前,原则上应该关掉放大器或接收器,直到各项连接均已建立。音箱应放在事先选好的
位置,以便能够测出合适的电线长度。两个声道应使用相同长度的电线。
然后给电线的终端留出10–15mm 做绝缘。将电线终端扭合起来 这个方法比包锡绝缘好
插入接线 柱,拧紧螺丝固定。(图 1)
在连接电线时,请您务必注意要接对正负极,即喇叭的黑色(-)端子与放大器的(-)端子相
接,而喇叭的 红色(+)端子与放大器相应的(+)端子相接。为了方便正负极的连接,市场上常
见的喇叭用线的一股线芯是带有纹路的或着了色,作为区别标记。
再仔细检查一遍电线的连接是否无松动,线芯是否翘出毛头,防止引起短路。短路会严重损
坏连接着的放大器。

当音箱的放置位置和视听位置构成一个等边三角形时,这个位置便是最佳视听位置。由于左
右两个音箱与听者之间的距离相等,音响信号于是同时从两边发出而形成一个自然而且均匀
的声振图象。(图 2)
听者应该能够目视两个音响。吸音体或声音反射体会使声音失真。此外,在放置喇叭时,应
注意保持下面规定的距离:
:距背面墙壁至少 20 cm,距侧面墙壁至少 30 cm。这样可以防止低音效果过
突出。
:如果音箱要放在书架上,那么它的周围也应留出足够的空间,距背面墙壁、侧
面墙壁以及物体至少要保持10 cm的间距,而高音喇叭应该放在听者耳朵的高度。
:放置音箱时,应使用随货一起收到的销钉,来消除喇叭和其放置托面的
耦合,从而防止产生不良的共鸣。如果是立式音箱,那您可以选用金属销钉或硬橡胶销 钉。
将销钉旋入音箱底面的螺纹套。

前置音箱应放在电视机的左右两侧,并且在听者耳朵的高度。它们与电视机的距离应尽可能
地相等。后置音箱应放在视听位置的左右两侧。如果能放在后方,则更为理想,并且要在听
者耳朵的高度或稍高处。(图 3)
