The Electro-Voice® RE90TX is an omnidirectional back-
electret condenser lavalier microphone designed for the
Architectural Series Microphone line. The RE90TX 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 RE90TX provide clean and accurate
sonic quality and uniform output regardless of the
microphone’s position relative to the sound source. The
RE90TX 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 belt or pocket. In addition, the
extremely compact size of the RE90TX is ideal for
performance or house of worship applications where the
microphone must remain as inconspicuous as possible to
the viewing audience. The RE90TX comes supplied with 4
feet of cable, terminated with a 4-pin TA4F connector, and a
tie clasp with non-reflecting black finish.
