KM 66 - The Figure-8 for an Even Sound Field

Occasionally, by combining elements of existing products,

previously unknown possibilities are discovered. One ex-

ample of this in Neumann’s product history is the KM 66,

a switchable-pattern miniature microphone first produced

in 1966.

In developing this micro-

phone, Neumann com-

bined two cardioid cap-

sules from the KM 64 in a

special way: the dia-

phragms face away from

each other with a spacing

of 10 mm; the backplates

are separated by an ellip-

tical divider. The result is

a capsule combination pro-

ducing excellent polar pat-

tern characteristics, even

in the extreme low-fre-

quency range. Even at

40 Hz, the rear-to-front

differential for each single capsule is 20 dB!

In an even (diffuse) sound field, no appreciable change in

on-axis (0 degrees) response occurs when switching from

omni to cardioid pattern. Also, when the backside capsule

is added (for omni), there is less than a 10% increase in

output voltage from the microphone.

In contrast, polar diagrams

of typical dual-diaphragm

microphones indicate that

the reverse attenuation of

the cardioid pickup pat-

tern decreases remarkably

towards the low frequen-

cies. When the two cap-

sule halves are activated at

the same time, the back-

side part adds a much

higher share of the whole

signal. This generates an

narrower figure-8 pattern

in the low frequencies and

an uneven response due to

changes in distance.

In the KM 66, the cardio-

id and figure-8 patterns

feature an accurate representation of low frequencies, even

in such a case where the microphone is used at a greater

distance from the sound source. This near-ideal carioid cap-

sule with its unique attributes is a great asset to other mi-

crophones utilizing it: the KM 64, U 64, KTM, KM 74 and

the legendary KM 84.
