and instrument live sound applications. These dynamic super cardioid
microphones incorporating neodymium magnets and aluminum voice
coil on the double membrane diaphragm and output transformer, that
provides higher output sensitivity, flat and wide frequency response. The
result is clean and detail sound texture demanded by the working
professionals.
The grill windscreen are made of strengthen metal mesh, added with zinc
alloy shaft and gold plated XLR 3 pin connectors provides sturdy
performance for heavy stage works.
