The JS-1 is a cardioid response, large diaphragm condenser microphone, designed to fulfill a variety of roles. The manufacturer says it is specially suited to applications such as vocals (including speech), general orchestral and spot miking of wind, brass and woodwind instruments, as well as strings (particularly cello and double bass) plus piano and percussion. It is also well-suited to for overhead drum and percussion applications.
The design criteria of for the JS-1 were strict - to offer exceptional performance in both acoustic and physical terms. The former is achieved by the use of a one inch super-thin 24K gold-plated externally biased Mylar diaphragm, coupled to advanced circuit design using the finest components, which delivers low self-noise, exceptional transient response and the transparent reproduction of acoustic characteristics.
