General Description:
The Electro-Voice®RE97Tx is an Ultra-low profile,
omnidirectional, back-electret condensor headworn
microphone designed for use with standard EV and Telex
belt packs. The RE97Tx is intended for spoken word use
such as Houses of Worship, Corporate AV, Theatre, Fixed
Install, and other venues where a full-range, natural, well-
balancedsoundisrequired.Theomnidirectionalpolarpattern
of the RE97Tx provides a clean and accurate sonic quality
and uniform output regardless of the microphone’s position
relative to the sound source.
The RE97Tx is designed to be extremely flexible and easily
formed to fit over the ear of any user. The malleable boom
and earhook can be shaped to match virtually any contour.
The TA4F terminated cable is discretely routed behind the
user and attaches to the shirt collar with the elegant clothing
clipincluded, keepingthecableoutofthewayandpreventing
the microphone from being pulled off the user’s ear. The
supplied windscreen can be used in windy environments
and to reduce breath noise.
The RE97Tx comes with a shielded 4ft cable terminated in a
high quality TA4F connector. It is wired for use with standard
EVandTelexbeltpacksincluding the EV(BPU-2/CSB-1000)
and Telex (WT-500/WT-1000) bodypack transmitters and
operates from a 5VDC supply.

Figures 1 through 3 show the ideal position of the microphone in use. The end of the boom should be located
approximately ½” (13mm) back from the corner of the mouth and as close to the face as possible. This position
will optimize the signal to noise ratio and minimize the acoustic effects of breath noise.
Themicrophone cable is routed
behind the neck of the user and
secured in place with the supplied
clothing clip as shown in Figure 4
and 5. Allow some slack in the cable
toenable the user’shead complete
range of motion in both directions
without pulling the cable from the
clothing clip.

Fitting:
1.Shape the boom: Figure 6 showsthe microphone boomas received. Before placingthe microphone over the
user’s ear, apply a slight bend to the boom, starting at the middle of the earhook, to aid the microphone boom in
forming to the user’s face.

The boom can be easily straighten by pinching between the thumb and forefinger, and applying pressure as
your fingers slide away from the earhook. The boom can be reshaped countless times without ill effect on the
performanceof the microphone or degradationofthe mechanical structure.
2. Fit to ear: Place the microphone over the ear. Press on the earhook from all sides to form it to the contour of
the ear. The shape of the earhook, as shipped, is designed to comfortably fit many users without adjustment.
To make the fit to the ear more secure, press on the top and bottom of the earhook using thumb and forefinger.
3.Adjust boom length:
If the microphone is positioned too close or too far away from the corner of the mouth (See Figures 1-3 for ideal
position), the boom length can be easily changed by reshaping the bend at the earhook. Figure 9 shows the
microphone as received. To bring the microphone closer to the mouth (i.e. lengthen the boom), simply straighten
out the bend at the earhook (Figure 10), and reapply the bend further up the earhook (Figure 11). To move the
microphone further away from the mouth (i.e. shorten the boom), follow the same procedure, but reapply the
bend further down the length of the boom. Changing the length of the boom will likely require re-shaping of the
microphone to the ear for optimum comfort.
