The microphone shall provide a three position control for normal (0 dB), elevated sensitivity (+6 dB), and attenuated (-10 dB) sensitivity. Switchable low-frequency cuts at 150 Hz and 75 Hz at 12 dB/octave shall be provided.

The polar pattern shall be cardioid and nominal on-axis frequency response shall be 20 Hz-20 kHz. For the normal sensitivity setting of 0 dB, microphone sensitivity shall be at least 20 mV/Pa, and the self noise floor shall be no higher than 11 dB-A.

C 480 B with CK 69/ULS

The microphone shall be of the condenser type with capsule and powering module assembly no larger than

0.8in. (21 mm) in diameter. The microphone shall accept phantom powering at 48 volts. The nominal output

impedance shall be equal to or less than 150 ohms at

1 kHz, and the output shall be transformerless. The microphone shall provide a three position control for

normal (0 dB), elevated sensitivity (+6 dB), and attenuated (-10 dB) sensitivity. Switchable low-frequency cuts at

150 Hz and 75 Hz at 12 dB/octave shall be provided.
