Wide cardioid
:
Pattern between omni-directional and cardioid
The wide cardioid pattern of the MKH 800 is, for example,
the result if the rear channel has 10 dB less amplification
than the front channel. The pick-up pattern becomes more
omni-directional at higher amplification and more cardioid
at lower amplification.
At the same time, the rear attenuation (180° attenuation)
of the microphone changes. It is the direct result of the
amplification ratio between the front and the rear channel,
i.e. 10 dB in the example of the wide cardioid pattern.

Super-cardioid
:
Pattern between cardioid and figure-8
The super-cardioid pattern of the MKH 800 is, for example,
the result if the amplification of the rear channel is 10 dB
lower than that of the front channel and if the phase of
the rear channel is inverted. At higher amplification, the
pick-up pattern tends towards the figure-8 pattern,
otherwise the pattern becomes more cardioid.
The cancellation angle at which the microphone is
especially insensitive also changes. It is 180° in the case of
the cardioid pattern, 120° for the super-cardioid pattern
and 90° for the figure-8 pattern. If the MKH 800 TWIN is
used as a supporting microphone, the attenuation
between different groups of instruments in an orchestra
can for example be optimised in this way. Here, too, the
rear attenuation is the result of the amplification ratio
between the front and the rear channel, i.e. 10 dB in the
case of the super-cardioid pattern.
