The UM 92.1 S studio microphone features our legendary PVC capsule M 7 which is renowned for its sound quality. This pressure gradient transducer uses two large diameter gold-plated plastic diaphragms. The UM 92.1 S has a remarkable signal-to-noise ratio and high sensitivity. It has the typical fullbodied sound of tube microphones that are preferred by vocalists and soloists.

Three directional characteristics (omni, cardioid and figure 8) can be selected with a pattern selector switch integrated into the power supply UN 920.1. The vacuum tube preamplifier is a well-established design equipped with a pentode working as high μ triode selected for its sonic characteristics.
