MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preampliﬁers directly above or below the

unit. Because this ampliﬁer has a high power density, it has a strong magnetic ﬁeld which can induce hum

into unshielded devices that are located nearby. The ﬁeld is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the ampliﬁer(s) in the bottom of the rack and the preampliﬁ er or other sensitive equipment at the top.

磁场

警告！不要把敏感的高增益设备，如前置放大器或大型录音机直接放在其上或者旗下，因为此功放具有大功率密度，形成强磁场，这种磁场会使靠近的未屏蔽的设备产生嘈杂声。扩音器的上部和下部磁场最强。

如果使用设备架，我们建议把功放放在架的底部，把前置放大器或者其他敏感设备放在架顶。
