极性控制

180°):MSubwoofer 可选择常规 (0°) 或反转 (180°) 相位。设置此开关以提供最丰满、最富动态的低 音。通过低频打击乐器或低音部分不断重复的音乐最能听出相位效果。

分频控制

调整 MSubwoofer 低通滤波器的频率。注:当使用 LFE 输入插孔时,此控制无效。

音量控制

MSubwoofer 音量控制钮转至 11 点钟位置。如果 MSubwoofer 未发出任何声音,请检查 AC 电源线、音频打 开开关、电源开关和输入电缆。

调整 MSubwoofer 音量控制,直到听到主扬声器和 MSubwoofer 彼此相匹配为止。低音响应不可压倒房间,应进 行调整以在整个音频范围内形成自然的混响效果。

保养和维修

每年应至少一次对所有电线连接进行检查和清洁。

如果发生问题,请确保所有连接均已正确进行,并且牢固、清洁。如果某一扬声器发生问题,在系统的不同位置重 新连接扬声器。如果问题仍然存在,则扬声器有故障。如果扬声器在新位置工作正常,很明显是系统的接线或电子 装备存在问题。如果您的扬声器需要维修,请联系当地 Boston Acoustics 经销商或访问 bostonacoustics.com网站。
