Sennheiser shows low-noise filter for MKH microphones
Sennheiser showed a new low-noise filter for its MHK 8000 microphones at the AES Convention in Munich. The MKH 8000 microphone series can now produce excellent sound and climate resistance in tough broadcasting and film applications.
The new filter module for the series, the MZF 8000, effectively suppresses handling and wind noise. The signal level can be lowered via a pad, thus allowing it to be optimally adapted to the recording equipment.
MKH 8000 microphones are compact, lightweight and can be used with telescopic microphone booms. The filter module now allows users to target and suppress unavoidable handling noise and to eliminate wind noise almost completely during outdoor recordings.
The MZF 8000 has two low-frequency filters: a roll-off filter that can be switched on when required, and a fixed low-cut filter that effectively suppresses frequencies below 20Hz. A switchable -10dB pad on the filter module reduces the signal level when required.
The MZF 8000 series features extremely low self-noise and comes as the MKH 8020 (omnidirectional), MKH 8040 (cardioid) and MKH 8050 (super-cardioid) RF condenser microphones. The filter module can be used with a remote cable as a separate unit, allowing the sound engineer to further reduce the weight on the boom. The module is transformerless and features a floating output.
