The E150 Series uses a micro-perforated stainless steel panel as a front grille with 2,300 holes and a diameter of just 0.25mm. The resulting effect reduces popping and sibilance without any negative impact on the overall quality. This technology is very common in aerospace and industrial audio measurement. It enables every nuance of the signal to be transmitted unaltered. Recordings sound extremely natural and rounded with high resolution and transient response. Polar patterns include: cardioid (E151), hypercardioid (E152) and omni (E153). Frequency response is 20Hz-20kHz with 48V phantom power.
