OVERVIEW
The 2011 Twin Diaphragm Cardioid Mic is a directional microphone. The distinctive sound of this microphone is well balanced. It bridges the gap between the extreme sound quality of our pencil microphones and our well-known Lavalier microphones.
An ultra-transparent preamp with active drive for impedance balancing. With rear cable entry.
