The performance requirements of a studio-quality condenser microphone are reviewed in light of present recording, broadcast, and sound reinforcement practice. Consideration is given to both electroacoustical performance and environmental stability. A condenser transducer is described which makes use of refined electret technology and demonstrates performance advantages over similar conventional, externally-biased configurations. The details of a new RLC Lossy Ladder acoustical phase shift network are presented in basic terms as applied to the design of a cardioid unidirectional microphone. Finally, a unique impedance conversion electronics section is described in terms of noise level, load driving capability, distortion, and environment stability.
