HM-28
The HM-28 is a hypercardioid ribbon microphone that can be used in a variety of recording and stage situations, offering great resistance and feedback rejection. It features strong bass, defined mids and smoother highs.
Design inspired by the German Beyer M160 first released in 1952. Most ribbon microphones have a bidirectional (figure-8) polarity pattern, capturing audio from both the front and rear of the microphone. The hypercardioid pattern captures only sound directly in front of the microphone, making it suitable for use on stage, where it is crucial to reject sound from the sides and rear to minimize feedback .
The HM-28 model has a carbon steel body, electrostatic painting in gray, iron transducer, 1/28 nanocrystalline transformer, neodymium magnets, steel grill and polished 6063T5 aluminum ring, aluminum ribbon element with 2.5 µ or 1.8 µ options.
