PRA-518 series are superior miniature gooseneck back electret condenser cardioid microphones for conferences. They are
designed to fit for the demands of conferences in aspects such as: tailored frequency response, excellent cardioid polar pattern,
and high gain before feedback.
With special care given in designing and manufacturing, the goosenecks hardly have any noticeable noise in flexing. Three
lengths and flexible modes are available to suit different occasions.
