Please explain the different pick up patterns (polar patterns) of the KSM9 models.
KMS9: cardioid pattern or supercardioid pattern. Selected by a toggle switch hidden under the mic grille.
KMS9H/S: hypercardioid pattern or subcardioid pattern. Selected by a toggle switch hidden under the mic grille.
Subcardioid: - 3dB at 90 degrees off-axis; -10 dB at 180 degrees off axis. Sometimes incorrectly referred to as a "forward-facing omnidirectional."
Cardioid: -6dB at 90 degrees off-axis; > -25 dB at 180 degrees off axis.
Supercardioid: -9 dB at 90 degrees off-axis; > -25 dB at 120 degrees off axis.
Hypercardioid: -12 dB at 90 degrees off-axis; > -25 dB at 110 degrees off axis.
* All specifications above based on an acoustic input signal of 1,000 Hz.
Off-axis rejection at 90 degrees:
Subcardioid: -3 dB
Cardioid: -6 dB
Supercardioid: -9 dB
Hypercardioid: -12 dB
Angle of maximum rejection:
Subcardioid: 180 degrees
Cardioid: 180 degrees
Supercardioid: 120 degrees
Hypercardioid: 110 degrees
