LF-3215 低频扬声器

简介

LF-3215 双 15” (381 毫米 ) 的低频机壳专为影院应用设计。LF-3215 和传

统 “摇滚”低音系统的不同之处在于它可以满足影院对扩展低频响应的要 求。根据高频系统的要求,LF-3215 可覆盖 32 赫兹到 1500 赫兹的频率范 围。由于低音扬声器之间间距小,因此和大间距设计相比,LF-3215 具有耦 合好,较大频率范围覆盖角度宽的特点。

300瓦,15” 变频器非常适合影院使用。它们采用 3” (76mm) 音圈,

120oz.(3.4kg) 陶瓷磁铁和通风极片 (确保低温运行)。温度低可以增加 变频器的寿命,并且减少高功率下的功率压缩问题。每个变频器的支架和音 圈可保证在高功率下的低失真和高重低音。

机罩由优质中等密度纤维板制成,所有面板都有加强支架支持,有独立的低 音室。在非常少见的情况下如果变频器出现故障,可以防止不当盒负荷造成 的变频器振幅过大。八个加强支架减少面板回响。

内部和外部端口开口都经过全辐射处理,确保气流在较高功率下可以平稳通 过端口。这可以防止声音端口噪音紊乱。

由于对称端口负荷 (SPL),低音端口均匀地分布在变频器两侧,使通过变 频器背表面的内部压力更加一致。这样就防止了圆锥由于力量失衡而被错误 地放置在一边或另一边,从而减少了高功率下将音圈赶出空隙中心的情况。

机罩上部的 3 个 T 形螺母使得安装 QSC HF-63 高频系统或 MH-1063 中高频 系统更加容易。

机罩并没有设计成悬挂式、可操纵式、或装配式。请勿对此机罩进行 悬挂、操纵或装配。

此产品可产生对人类听觉造成永久损伤的声压强度。请将听音区域内 的声压强度总是保持在不会对人的听力造成损伤的水平。

按照 QSC Audio Product 的说明并在授权的专业工程师的指导下安 装。仅限使用 QSC Audio Product 公司规定的附件、底座、零件或支 架。所有维护请由合格的专业人士进行。设备如果受到损坏,就需要 进行维修。

警告!放置、安装、装配或悬挂扬声器产品时,检查所有硬件、悬 架、搁柜、变频器、支架和相关设备有无损坏。任何额定部件的缺 失、腐蚀、变形或未装载都可能大大降低安装、放置或排列的强度。 出现任何严重降低安装安全度的情况应立即更正。仅限使用额定安装 的硬件及任何可能的短期突发超载。切勿超过硬件或设备的额定标 准。如有任何关于物理设备安装的疑问或问题,请咨询获得许可的专 业工程师。
