宝贝详情2009年在Frankfurt举办的ProLight+Sound/Musikmesse 上，AKG以很高的评价宣布了Perception话筒系列的最新产品?Perception 820 Tube。Perception 820 Tube为Perception系列家族中的一员，其产品还包括P 120, P 170, P 220以及 P 420。每个话筒都上的20分贝的衰减器和低阻滤器有利于扩增话筒在嗓音，铜管乐器，电吉他扩音器以及overhead miking等方面的功能。AKG负责录制和传播产品的市场拓展经理Thomas Stubics说道：“AKG Perception 820 Tube话筒作为新一代的旗舰产品不仅仅带来的是热情和出色的声音质量，更重要的是提高了这个价位管状话筒的标准。” “与其他的管状话筒相比，Perception 820 Tube表达了更加真实的管状声音质量。我们对于即将发布此产品的期望值非常的高，我们也非常高兴能在Messe上发布Perception 820 Tube。”Perception 820是由一个双重一英寸的真正电容式大型振动膜包裹，一次传递清晰精确地信号，尤其适用于主音，铜管乐器，overhead miking以及其他的应用。ECC 83双三极管管状电路以及输出变压器意在为饱满的，流畅的立体声制造出偶次谐波。远程控制单元允许从全方位指向性，心形指向性到8字型指向性等9种不同的指向性中进行选择。另外，它也可以控制可切换的二阶削低频滤波器以及可切换的衰减器。此外，提起式接地开关可以防止不必要的杂声。通过粉刷而进行阳极化处理的铝制前面板以及全金属外罩确保了防止外界无线电频率的干扰。由奥地利维也纳设计制造的整个Perception生产线给AKG带来了独有的音质。其由坚固耐用的锌铝合成材料制成的不锈钢格子屏幕就是独有音质的良好保证。此外还有抵抗外界压力的作用。
