Sennheiser Electronics Corporation MKH 40
Cardioid Pencil Condenser Microphone
The MKH 40 is an end-address rf-condenser with a Cardioid polar pattern.
This is a popular mic for field and SFX recording, often used as the “mid” mic in a mid-side coincident stereo configuration, usually with an MKH 30 for the “side” channel.

The MKH40 and MKH30 is the de-facto standard for nature recordists and those who record stereo ambiences.
The published polar graph shows a pure Cardioid pattern, with a deep null at 180°, below 2kHz. Above 4kHz, the pattern narrows slightly, becoming Supercardioid (with nulls at plusmn;120°) above 16kHz.
The frequency response graph is ruler-flat from 40Hz to 20kHz. With the optional HPF enabled, frequencies below 500Hz are mildly attenuated, 0-4dB.
The mic uses Sennheiser’s RF Condenser technology, which uses a low polarization voltage and loose diaphragm tension to produce a very low self-noise (12dBA), high-sensitivity (25 mV/Pa) transducer.
Like the other mics in the MKH 20/30/40/50 series, the MKH 40 uses a 20mm capsule with a 15.5mm diaphragm made of 3.5-micron Mylar.
The mic ships with the MZS 40 shockmount, and MZW 41 foam windscreen.
The Sennheiser Electronics Corporation MKH 40 is also known as: MKH40.
