Gefell UM930 twin

The Gefell UM 930 twin is a dual condenser microphone with switchable polar pattern. High output level and exceptionally low noise.

The Gefell UM 930 twin switchable pattern studio condenser microphone combines modern large diaphragm capsule technology with the latest in semiconductor circuit topology. The optimized dual-capsule assembly opens up new applications in recording techniques. In addition to conventional switched patterns, two different directional patterns can be selected at the same time.

The Gefell UM 930 twin is specifically designed to meet the needs of professional and semi-professional users who demand the highest performance. This microphone is ideally suited for universal miking applications in broadcast and sound studios. Applications include vocalists, announcers, dialog pickup and as spot microphones for recording guitars, keyboards, percussion, wind and string instruments.

The microphone is side addressed. The front shows the model type and the polar pattern inscription.
