تم تصميم كبسولة الميكروفون المصغرة Neumann KK145 لتلائم المضخمات الأولية لنظام الميكروفون الرقمي KM-D. يُعد النمط القطبي القلبي للكبسولة فعالًا في تقليل التقاط الأصوات الارتدادية خارج المحور ويتميز بتدوير جهير صوتي Bass Roll-off. يعتبر النمط القلبي مثاليًا عندما تكون التحكم بارتداد الصوت و الصوت في المحيط ضروريًا.
الميزات:
The Neumann system KM A/D is a modular microphone system for even the most demanding applications. Eight different small diaphragm capsules (KK 120 … KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). All components are available in nickel or Nextel black (nx). A comprehensive range of accessories ensures adaptability to the most diverse fields of application.
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.
The KK 145 is a pressure gradient transducer with cardioid characteristic just like the KK 184. However, it has an acoustic bass roll-off in the free field and therefore suppresses LF interference (wind, structure-borne noise). Since proximity effect is a natural feature of pressure gradient microphones, the KK 145 is optimized for a flat frequency response at a recording distance of approximately 15 cm („speech cardioid“).
