KK 145 nx + KM A nx

在模拟和数字模式中保持最大灵活性

KK 145话筒头与输出级KM A的组合是诺音曼KM A/D小振膜话筒系统中的众多选择之一。

诺音曼KM A / D系统是一种模块化话筒系统，能够满足最苛刻的应用需求。八种不同的小振膜话筒头（KK 120 - KK 185）可与模拟输出级（KM A）或数字AES 42输出级（KM D）组合使用。所有组件均有镍色或黑色可选。丰富的安装配件，可满足多种场合应用需求。

Dealer Description

与其前身KM 100系列相比，新系统KM A / D可与体积较小的无源话筒头搭配使，同时保留了经典的声学设计。

全新的电子组件具有许多电声和操作优势，例如本底噪声降低、动态范围更大和非常高的抗电磁干扰性能。

The modular concept permits the capsule to be detached and used at a distance from the output stage of up to 100 m (330 ft), connected via a special cable. For usual applications, the LC 4 cable is available with a length of 5 or 10 meters (ca. 16½ or 33 ft.). Alternatively, capsule extensions of various lengths, swivel capsule joints, and swivel stand mounts, etc. may be used for a flexible microphone setup. The analog and digital output stages have identical dimensions (diameter: 22 mm, length: 93 mm). All accessory parts may thus be combined with both output stages.

A lot of examples for using the accessory portfolio can be found here.

The Output Stages

The analog, transformerless output stage KM A operates with P48 phantom power. A switchable -10 dB preattenuation allows for sound pressure levels of up to 152 dB (depending on capsule type) without distortion artifacts.

The digital output stage KM D is compliant to the AES 42 standard and opens entirely new possibilities, unattainable in the analog domain. The integrated DSP permits remote control of microphone parameters, such as digital gain, preattenuation (6, 12, 18 dB) and low cut (0, 40, 80, 160). An integrated peak limiter and a compressor/limiter with an additional de-esser function protect the audio signal from overload. Neumann’s patented A/D-converter technology ensures a very high dynamic range of up to 122 dB-A across the entire digital production chain.

At any time the user may opt to work in the analog or digital domain, without the expense of a complete system change, simply by using the KM A or KM D output stage. More information on Neumann’s digital microphone technology is available here.

Two popular combinations are available as complete sets with capsule, output stage and swivel mount: KM 183 A nx and KM 184 A nx. Any other components are offered separately.

Compability with the Neumann KM 100 System

On special request, a mechanical adapter (AR 100 KA) can be supplied for use of older KM 100 capsules (AK series) with the KM A and KM D output stages.

KK 145话筒头

KK 145是一种压力梯度式换能器，并具有与KK 184相同的心形特征。但KK 145在自由场中表现出低音衰减，因此可以抑制低频干扰（风声、结构噪声）。由于近讲效应是压力梯度式话筒的一种自然特征，因此在大约15 cm的录音距离，根据平坦频率响应的要求对KK 145进行了优化（“人声心形”）。
