DFM-400

项目编号: 1342-XXXXX

DFM-400 是一个有源中低频模块,采用Fohhn波束转向技术,它可以灵活地与高频模块DFM-100 / DFM-110组合。我们著名的新一 系统现在已经完全数字化,并提供进一步开发的Fohhn DSP和数字信号连接。经过声学上的重新设计,配备了更加强大的驱动器,DFM提供了出色的、发烧级的声音和最佳的语言清晰度。一个高品质和高性能的解决方案,适用于大型会议室、剧院甚至是露天音乐会。而所有这一切都与一个仅有约22厘米宽的箱体有关,由于采用了波束转向技术,它可以直接吊挂并无缝集成。DFM-100 DFM-110 Focus Modular Fohhn DSP
