Electro-Voice | RE3-RX RE3 Diversity Receiver
RE3-RX RE3 Diversity
Receiver
▪Diversity reception minimizes dropouts
▪Up to 36 MHz tuning bandwidth (band specific) for
trouble-free operation
▪Easy-to-read LCD display
▪Frequency scanning for selecting open frequencies
▪Sync function links transmitter to receiver for easy
setup
The RE3-RX is a professional rack-mountable, ½ space
diversity receiver. Designed to function as the control
center for an RE3 wireless set, it features frequency
scanning and synchronizing, as well as full transmitter
control settings which synchronize to a mated
transmitter.
The diversity reception technology minimizes the
chances of signal dropouts by providing two separate
antenna locations which are electronically chosen
moment-by-moment based on signal strength and
stability. The wide tuning bandwidth provides access
to a wide range of frequencies, selectable in 25kHz
steps for trouble-free operation of single and multi-
channel systems. The easy-to-read LCD display
provides vivid viewing of all menus and operating
parameters. The easy-to-use frequency scanning
function simplifies locating and tuning to a clear
operating frequency. The sync function wirelessly
synchronizes all operating parameters to the mated
transmitter.

3. Power on the transmitter.
4. Ensure the transmitter mute switch is disengaged.
5. Ensure the transmitter’s attenuation is set to OFF.
6. Adjust the input sensitivity so that the highest voice
peaks light the RE3-RX receiver’s AF meter’s yellow
LED segment (the sixth LED from the bottom).
Be careful that the transmitter’s audio signal level does
not cause the receiver’s AF meter red LED to light often.

Electro-Voice | RE3-BPT RE3 Bodypack Transmitter
RE3-BPT RE3 Bodypack
Transmitter
▪Robust metal body
▪Up to 36 MHz tuning bandwidth (band specific)
▪Selectable low and high output power (band
specific)
▪Unique magnetic latch and lock for easy access to
batteries
▪Sync function for easy frequency setup
The RE3-BPT is a small, lightweight yet robust UHF
bodypack transmitter. It is easily worn and concealed,
making it an ideal form factor for a wide variety of
professional presentation and performance
applications. From stand-up presentations, to
theatrical and musical performances, to high-energy
fitness and athletic situations, this sleek and rugged
transmitter fits comfortably and accepts a wide variety
of input devices.
The all-metal body is robust and durable, and operates
on 2 AA alkaline or rechargeable NiMH cells. The
tuning bandwidth affords generous frequency tuning
options helping to avoid various sources of possible
interference. The selectable output power (band
specific) assists in overcoming the challenges of both
long, or short, transmission ranges. The unique
magnetic sliding latch and lock mechanism keeps the
battery door closed securely and makes opening to
access the batteries effortless. The ultrasonic sync
function makes for a simple system setup by syncing
the transmitter to the receiver frequency tuning and
other functional data. Recharging contacts provide for
functional use with the optional BC2 charging station
allowing the NiMH rechargeable cells within two
bodypack transmitters to be charged without removal.

• Use only disposable LR6 (AA) alkaline or NiMH
batteries.
• Do not mix new batteries with old ones in the
transmitter at the same time.
• Do not use different battery types or models.
• Do not use a leaking battery. If battery leakage
occurs, avoid contact with skin. If contact occurs,
immediately wash thoroughly with soap and water.

RE3-ACC-CL3 Cardioid
lavalier mic with TA4F
▪Ideal for general sound reinforcement and
presentations
▪Cardioid polar pattern rejects ambient sounds and
increases gain before feedback
▪Delivers full and accurate sound
▪Wide dynamic range and frequency response
▪Clothing clip holds microphone securely and
attaches easily to garments
The CL3 is a robust, general-purpose lavalier
microphone. It is ideal for presentation and public
speaking where its full and accurate sonic
characteristics, coupled with its feedback-rejecting
cardioid polar pattern deliver a clear and intelligible
voice. The cardioid pattern provides acoustic isolation
and gain before feedback in situations where the
ambient sound reinforcement system volume might
cause an omnidirectional lavalier to feed back. The
small clothing clip attaches the microphone securely
to clothing items or surfaces. The included foam
windscreen is effective in reducing wind noise. The 4-
pin mini plug is compatible with all current Electro-
Voice bodypack transmitters, as well as many other
brands who use the 4-pin mini connector convention.
