The RF principle of their operation gives extremely low inherent self-noise, as well as high climatic resistance and low distortion with relatively high output signal voltages. RF microphones are inherently fully floating and balanced and do not require an additional balancing circuit or transformer to protect them from external interfering signals.
The MKH 8060 measures 14.5cm and weighs 112g (with XLR module) for use as a camera or boom microphone. Its range of applications includes outdoor recordings, studio applications for film and television or as an audience microphone for mixing audience reactions.
The MKH 8070 features an extreme directivity that enables pick-up of very distant sounds. For broadcasters, this microphone will be well-suited to sports events, as well as for film and television recordings, both in the studio and outdoors. It is also especially useful for nature and wildlife recordings.
‘For the new shotgun microphones, a natural, lifelike sound was very important for us,’ says for Kai Lange, Product Manager Professional Wired Microphones at Sennheiser. ‘Sound engineers are often faced with the problem that gun microphones can colour the sound if they are not aimed precisely at the sound source. This is a disadvantage particularly in interview situations, as the character of the speaker’s voice is altered. For that reason, the MKH 8060 and MKH 8070 are designed in such a way that the sound signal only becomes quieter if the sound source does not lie on the axis of the microphone.’ This is particularly important when indoors where off-axis room reflections can colour the sound; this effect is minimised with the new design of the interference tube in the microphones.
Digital module and filter accessories
As a member of the MKH 8000 family, both microphones can be combined with the MZD 8000 digital module, turning them into digital microphones according to the AES42 specification. In combination with the DMI 2 portable interface from Neumann, the new shotgun microphones may be used for mobile, digital broadcasting. Also available is a filter module (MZF 8000) which features a switchable -10dB pad and a switchable roll-off filter that further suppresses any wind noise that might penetrate a ‘hairy’ cover and basket windshield.
For unobtrusive use of the MKH 8060, the XLR module of the microphone can be removed and the microphone head connected to a remote cable or extension tube. The microphone can be mounted onto smaller cameras or used for more unobtrusive fixed positioning in a TV studio. All microphone modules are Nextel-coated to avoid irritating light reflections.
