Neumann KH 120 5.5英寸有源监音响
KH120有源监听音箱可作为近场监听音箱使用,或者在大型环绕声监听环境中担任环绕音箱的角色。由于在设计和制造过程中采用了最新的电声仿真及测量技术, KH120在最大程度上保证了精确的声音还原。KH120的高频波导采用了"数字建模辐射"Mathematically Modeled DispersionW(MMDM）技术,具有灵活的声音
控制手段,装备模拟电路的甲乙类放大器,能支持不同格式的输入,并可以选择多种安装附件。所有这些,都给用户在不同声学条件,播放设备,以及安装位置下使用监听音箱提供了最大的灵活性
如果需要扩展低频下限、提升系统的最大输出声压级, 还可以选用能支持7.1回放,带有高解析度低音管理系统的Neumann KH810次低音音箱,低频响应可以达到18Hz。KH120是音乐、广播、工程、以及后期制作领域中,应用在录音、缩混、母带制作等各个环节的完美选择。
