The Electro-Voice® RE90L is an omnidirectional back-

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

housing features a side clip to facilitate attachment to a
