The Earthworks P30/HC is a directional prepolari-zed condenser High Definition Microphone™ with a first-order hypercardioid pickup pattern directly coupled to a dedicated wideband, low output impedance transformerless preamplifier. The P30/HC requires a standard 48V phantom power supply. It features a flat frequency response from 30Hz to 30kHz (Fig. 2), fast impulse response (Fig. 3), very low handling noise, uniform polar pattern, and high SPL handling capabilities. It provides uncolored rejection of sounds arriving off-axis.
Each microphone is delivered with its own calibration chart providing the individually measured frequency response curve. A mounting clip is included with the microphone.
