The Electro-Voice® RE90L is an omnidirectional back-  
electret condenser lavalier microphone designed for the  
Architectural Series Microphone line. The RE90L is  
intended for sound reinforcement applications such as  
houses of worship, schools, or other venues where full-  
range, natural, well-balanced sound is required. The  
omnidirectional polar characteristics of the RE90L provide  
clean and accurate sonic quality and uniform output  
regardless of the microphone’s position relative to the  
sound source. The RE90L is designed to attach to the  
talker’s clothing using the supplied clips. The electronics  
housing features a side clip to facilitate attachment to a

inconspicuous as possible to the viewing audience.
