Description and Applications
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 belt or pocket. In addition, the extremely compact size of the RE90L
is ideal for performance or house of worship
applications where the microphone must remain as inconspicuous as possible to the viewing audience.
Powering the RE90L
The RE90L is powered by an external 9- to
52- volt phantom power supply. The electronics circuitry is wrapped with an insulated
copper foil for superior emi/rfi shielding. The
module is enclosed in a high-strength polycarbonate resin housing to form a package that
is very light-weight and extremely durable for
outstanding reliability and long life.
Operation
To operate the RE90L use high-quality balanced cable with 3-pin XLR-type connectors
to connect the electronics housing to the
mixer input which is providing the phantom
power. The connecting cable used should be
standard two-conductor shielded type; the
shield is used as ground return and must be
properly connected to avoid electrical noise.
Microphone Placement and Cord
Looping
Typical microphone placement is shown in
the illustration. For best results, the RE90L
should be positioned as close to the mouth as
possible. It is important to loop the cable
as shown to eliminate cable rustling noise.
Windscreen
Use the external windscreen to prevent wind
and pop noise.
