Neumann KH 310 监听音响
KH310A是一款有源近场监听音箱,可满足音乐制作、广报、后阴圳作、混音和母带制作等领域的应用需要。它也非常适合作为中等尺寸环绕声系统中的前置音箱使用,或是作为更大型多声道系统中的后置普抓使用,
音箱驱动单元全部由Neumanm 设计开发,并且经过了声学模拟和一系列测量及测试。长冲程低频驱动单元确保了在高声压退的况下也能您在银低的失工
通过一只专门设计的中频驱动单元,能够满足处于中频范国内语音和人声的精确重放。高频重放通过一只位于销四形
Mathematically Modeled Dispersion"(MMD)彼导管中的软硬复合球顶驱动单元来完成。从而在一个更宽的可用听音区域范围内实现清晰透明的重放效果,并且在垂直面上实现了反射的晨小化。
KH 31OA 采用封闭式音箱箱体,并提供低频、中频以及高级的声学控制手段,使其成为声学受限空间环境中一种有效的解决方案。这些环境包括个人录音棚、后期制作录音掘以及使析维
