Pressure Transducers
Microphone Capsule MK 2H
– omnidirectional pattern
– mild high-frequency rise to compensate for losses at
medium recording distance
– often chosen for “spaced microphone” stereo pick-
up and “Decca Tree” arrangements
If this microphone capsule is used indoors at medium
recording distances (i.e. where direct sound energy is
similar in amount to reflected sound energy), its over-
all response will be linear. Its extended frequency
response and low noise make it appropriate for the
most demanding applications.
The sound inlet of the MK 2H is narrower than that
of our other pressure transducers, causing a slight,
purely acoustic response elevation above 6 kHz. This
reduces the high frequency loss for diffuse sound, thus
helping to preserve natural sound quality.
The MK 2H, like the MK 2S, is ideal for natural-sound-
ing pickup of instruments and orchestras in spaces
with well balanced reverberance. The choice between
the two capsule types is essentially a matter of personal
preference. At a given miking distance the MK 2H
might be described as more ”balanced and round”
sounding while the MK 2S would give a slight addi-
tional brilliance. However, one might also choose the
MK 2H for slightly closer placement or the MK 2S for
slightly more distant placement – and then these two
capsule types would have very similar sound quality,
with the main difference being the balance of direct
to reverberant sound which is picked up.
For spaced microphone (“A/B”) stereo recording and
especially the “Decca Tree” method, KA 40 accessory
spheres are recommended; please see page 114.
