General Description
The MKH 40 has a large number of applications, for example as a main microphone, especially in lightly reverberant or acoustically less perfect rooms, with instrumental groups or for speech applications. Its wide-angled, neutral directional characteristics and high level of reverse attenuation ensure an exceptionally balanced sound.
Features
	Maximum front-to-back ratio
	Exceptionally low inherent self-noise
	Symmetrical transducer technology ensures extremely low distortion
	Transformerless and fully floating balanced output
	Switchable roll-off filter to compensate for proximity effects at a distance of approx. 0.5 m
	Switchable pre-attenuation
	Black, anodised light metal bodv
Delivery Includes
	1 MKH 40, 1 MZS 40 shock mount,
	1 MZW 41 windshield
