Pressure Transducers
Microphone Capsule MK 2S
– omnidirectional pattern
– slight high-frequency rise to compensate for losses
at moderate recording distances
– for a very wide range of recording applications
– often preferred for “spaced microphone” stereo
pickup and “Decca Tree” arrangements
The MK 2S exhibits a slight high-frequency emphasis
for frontal sound inci dence, with only a slight rolloff of
high frequencies off axis and in the rever berant sound
field. This frequency response characteristic falls between
that of the MK 2 and the MK 3, making the capsule
suitable for a wide range of applications. The MK 2S
has proven particularly useful in two- and three-micro-
phone stereo arrays, where its placement near the
reverberation radius of the sound field (see page 130)
presents a sonically balanced pickup favored by many
recording engin eers. This model has become our most
popular pressure transducer.
For spaced microphone (“A/B”) stereo recording and
especially the “Decca Tree” method, KA 40 accessory
spheres are recommended; please see page 114.
