*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.

Figure-8 왘 Set the amplification to the same

value in both channels.

왘 Invert the phase of the rear

channel.

Super-cardioid** 왘 Set the amplification in the rear

channel lower than in the front

channel.

왘 Invert the phase of the rear

channel.
