Wide Cardioids
Microphone Capsule MK 21H
– wide cardioid pattern with especially consistent
directionality throughout its frequency range
– high-frequency elevation for brilliance of sound
– often preferred for use when recording vocals,
acoustic guitar or percussion
This capsule type is an outgrowth of our field experi-
ence with the MK 21. It embodies suggestions made
by various pop musicians who wished certain instru-
ments (such as percussion, acoustic guitar and vocals)
to be reproduced with a touch of additional brightness,
while maintaining the essential uniformity of response
to sound originating anywhere in the capsule's front
hemisphere.
The frequency response of the MK 21H rises at high
frequencies, reaching +4 dB at 7 kHz. Unlike most other
condenser microphones, this capsule's response does
not then roll off, but “stays up” even at very high fre-
quencies.
As with our MK 21, the frequency response of this
model is exceptionally consistent for all directions of
sound incidence.
