{"product_id":"akg-hc644-md","title":"AKG HC644 MD, Head-Worn Microphone, Studio-quality sound, Flat frequency response for natural sound, High RF rejection","description":"\u003cp\u003eFollowing up on the legendary performance of the C544 and C555, AKG has created the next generation of head-worn microphone, the new HC644 MD. This high-performance head-worn condenser microphone is the perfect tool for presenters in the corporate market but also ideal for sport applications like aerobics. More and more wireless systems in the low to mid-price range are based on 2.4 GHz technology causing nasty interference with microphones. The new HC644 MD is well protected against those problems. The main improvements of the new version are a smaller capsule design with a higher sensitivity, an exceptional RF shielding, a sweat-resistant design and the ability to fit to all major wireless systems on the market.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStudio-quality sound\u003c\/li\u003e\n\u003cli\u003eFlat frequency response for natural sound\u003c\/li\u003e\n\u003cli\u003eHigh RF rejection\u003c\/li\u003e\n\u003cli\u003eFor safe performance even in RF sensitive environments\u003c\/li\u003e\n\u003cli\u003eHighly moisture-resistant design\u003c\/li\u003e\n\u003cli\u003eReliable operation even in extensive use\u003c\/li\u003e\n\u003cli\u003eUniform polar pattern\u003c\/li\u003e\n\u003cli\u003eReduces feedback\u003c\/li\u003e\n\u003cli\u003eMicrodot adapter\u003c\/li\u003e\n\u003cli\u003eAvailable adapters for most wireless systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Back-electret condenser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolar Pattern:\u003c\/strong\u003e Cardioid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity (1m):\u003c\/strong\u003e 20 mV\/Pa (9V\/18kOhms)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio frequency bandwidth:\u003c\/strong\u003e 100 - 15000 Hz (+\/-3dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical impedance:\u003c\/strong\u003e 200 Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended load impedance:\u003c\/strong\u003e 2000 Ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquivalent noise level:\u003c\/strong\u003e 34 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal to Noise (1Pa):\u003c\/strong\u003e 60 dBA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax.
