General Description: Technical Specifications:
The Electro-Voice® RE97LTx is an ultra-miniature,
omnidirectional, condenser microphone designed for
applications that demand a high quality microphone
element that is practically invisible when worn by
the speaker or performer. The RE97LTx is intended
for spoken-word use in theatrical performance, fixed
installations, corporate AV presentations, houses of
worship, or any venue where a full-range, natural, and
well-balanced sound is required from an inconspicuous, lightweight microphone.
The output of the RE97LTx is clean and accurate, while
the omni-directional polar pattern ensures uniform
output regardless of the microphone’s angle relative
to the sound source. The provided clip is a convenient
anchor for the microphone on a lapel, tie, or shirt collar.
The supplied windscreens can be utilized in windy
environments and to reduce breath noise. The RE97LTx
has a shielded 4ft cable terminated in a genuine
Switchcraft® TA4F connector and is ready for use
with standard EV and Telex body-pack transmitters
including the EV REV-BP, BPU-2/CSB-1000 and Telex
WT-500/WT-1000. The wire to the body-pack is ultraflexible, and may be easily concealed.

Windscreen Assembly:
The windscreen assembly is supplied with a plastic
adaptor to improve stability.
To apply: Hold the windscreen firmly at the “A” locations. Firmly press the microphone into the adaptor
until it stops.
NOTE: Use caution when removing the microphone
from the windscreen. Do not pull on product wire: grip
microphone by metal housing only.

Microphone Positioning:
Best results will be achieved with the microphone positioned 3 to 6 inches below the neckline. Typical locations
are on the lapel, shirt collar, or on the shirt directly below the chin. You should avoid covering the microphone with
any cloth or other material as this may change the frequency response characteristic of the microphone.
If mechanical noise from the cable is detected, it may be minimized by looping the cable up and through the dual
tie clip as shown in the picture on page 1, or by immobilizing the cable against the talker’s body.
