主要特点

LC-220 是一款用于固定安装的无源线声源扬声器。它为出色的语音重现进行了优化，并且由于其防风雨的铝制外壳，非常适合于室内和室外应用。著名的Fohhn线声源扬声器在一个紧凑的系统中结合了线阵列的优点--如方向性、均匀的扩散和覆盖范围。纤细的铝制外壳能够在视觉上完美地融入房间的结构。

18 × 4 "驱动器
额定功率：440 W
频率范围：120 Hz -12 kHz
抑制不需要的旁瓣得益于Fohhn Source Division Waveguide
完美的语音清晰度和长距离的投射
低阻抗技术
安装“电缆接头套件”（随附）后，防护等级为IP65，符合EN/IEC 60529标准
可提供不同的颜色（RAL经典色、Pantone色、NCS色）或与Fohhn Texture Design
为确保最佳性能和运行可靠性，必须使用Fohhn 系统功放，并选择正确的扬声器预设。
