DESCRIPTION  
• Separate LEDs for power on and battery status  
for easy monitoring of operational modes.  
The Electro-Voice R100 is a series of VHF wire-  
less systems that combine EV’s legendary quality  
and reliability with high value. The R100 Series  
transmitters and receivers operate in the VHF fre-  
quency range between 174.100 and 185.350 MHz  
(channels 7 – 8 in the TV band) on single frequen-  
cies. The well-designed audio circuitry ensures  
high signal-to-noise ratio with accurate sound  
quality.  
• Separate power and audio mute switches for  
operational flexibility.  
• Wide-range gain control allows approximately  
30 dB of adjustment.  
• Special “soft-touch” finish and ergonomically  
designed handle makes holding comfortable  
and secure.  
SECURE-PHASEtm DIVERSITY  
• Up to 10 hours of operation on a 9-volt alkaline  
battery.  
The R100 Series receivers utilize patented Se-  
cure-Phasetm diversity circuitry that provides the  
strongest, cleanest signal possible. Unlike other  
diversity circuits that switch antennas, Secure-  
Phasetm utilizes the signal from both antennas at  
all times to increase signal strength, minimize  
dropouts and lower the potential for interference.  
Bodypack Transmitters  
• A variety of models are available:  
• BLV: VHF bodypack with hardwired OLM10  
omni-directional lavalier condenser microphone  
• BPV: VHF bodypack with TA4F connector al-  
lows the user the freedom of microphone se-  
lection.  
If the signal from the transmitter changes phase  
or polarity (a common cause of dropouts), the cir-  
cuit adjusts the phase angle between the two an-  
tennas receiving circuits to prevent cancellation.  
• BEV: VHF bodypack with hardwired Electro-  
Voice HM2 cardioid headset condenser micro-  
phone

QUICK SETUP AND USE  
5. Turn the output level control (see Figure 1) on  
the front panel to the 12:00 o’clock position  
(midway in the control’s range).  
To get your system into operation quickly, use the  
following instructions. Review the rest of the manual  
for additional setup and operational details.  
6. Setup and adjust the transmitter level as de-  
scribed on the following pages.  
1. Place the receiver where there is a clear line  
of sight to the area where the transmitter will  
be used. Extend the receiver’s antennas to  
full length and separate them 90 degrees (see  
Figure 1).  
7. Turn up the level on the mixer or preamp to  
the desired setting.  
8. Speak into the microphone or strum the instru-  
ment and, if necessary, adjust the receiver’s  
output until the volume level from the wireless  
system approximates the level of an equivalent  
wired microphone or instrument.  
2. Make sure the sound system’s volume is low  
or off on the input you intend to use for the  
wireless.  
9. “Walk” the expected area of use to check for  
dropouts or interference. If problems occur,  
see the troubleshooting section.  
3. Plug in the receiver’s power adapter into an  
AC outlet and the other end into the receiver.  
CAUTION: Please make sure that the AC  
adapter is the correct voltage for your lo-  
cal requirements.  
4. Plug one end of your audio cable (not sup-  
plied) into the output connector on the front  
panel of the receiver.  
Figure 1  
Figure 2  
or high (distortion), adjustments are neces-  
sary. Gently insert the provided screwdriver  
(or other 3/32-in. flat head screwdriver) into  
the hole near the head of the transmitter (see  
Figure 4). Turn lightly until the screwdriver  
tip drops into the slot in the level control. Gen-  
tly turn counterclockwise until the control  
stops (the mic output is attenuated but not  
“off”). Slowly turn the mic-level control while  
listening to the audio. If the audio becomes  
distorted, turn the mic level control counter-  
clockwise about 1/8 turn.  
HTV HANDHELD TRANSMITTER SETUP  
1. Insert battery. Slide open the battery com-  
partment cover by pressing lightly with your  
thumb on the horizontal grooves (at the back  
end of the transmitter) while gently pulling  
back (see Figure 2).  
2. Turn on the transmitter by sliding the power  
switch (nearest the battery compartment) for-  
ward, toward the mic element. Both red and  
green LEDs above the power switch should  
be illuminated, indicating power on and good  
battery condition.  
6. Adjust the squelch control if necessary.  
The squelch control on the back of the re-  
ceiver may be adjusted to increase range or  
reduce interference. Turn the control counter-  
clockwise to increase range. Caution! In-  
creasing the range will make the system  
more susceptible to outside interference!  
If the squelch is being adjusted, turn the  
transmitter off. Turn the squelch control  
counter-clockwise until you hear noise or in-  
terference. Then, turn the squelch clockwise  
until the noise is gone.  
3. Check reception. Observe that the audio  
carrier light on the front panel of the receiver  
is illuminated, an indication that the receiver is  
picking up the signal. Then, “walk” the in-  
tended area of use and make sure that there  
are no barriers to reception or sources of in-  
terference.  
4. Unmute the audio by sliding the audio switch  
(immediately below the mic element) towards  
the windscreen.  
5. Adjust the gain if necessary. First, speak or  
sing into the microphone and listen closely for  
distortion or hiss. If the gain is too low (hiss)

5. Turn on the audio transmission by sliding  
1. Insert battery. Open the hinged battery com-  
partment by placing your thumb or finger on  
the indent on the battery door and pull down.  
When inserting the battery, pay attention to  
the polarity (+/-) and insert the terminals first  
into the battery compartment. Close the bat-  
tery door by sliding the door shut.  
the large mute switch to the “on” position.  
6. Listen carefully to the audio and be sensitive  
of overload distortion and low gain or hiss.  
7. Adjust the gain if necessary. Gently insert  
the provided screwdriver or other 3/32-in. (2.5  
mm) screwdriver into the gain adjustment lo-  
cated at the top edge of the battery compart-  
ment under the door. The door has to be  
opened but not swung upward to make ad-  
justments. Turn lightly until the screwdriver tip  
drops into the slot on the level control. Gently  
turn the control counterclockwise until the  
control stops (the audio output is attenuated  
but not “off”). Slowly turn the audio level con-  
trol clockwise while listening to audio; if the  
audio becomes distorted, turn the mic level  
control counter-clockwise about 1/8 turn.  
2. Turn on the transmitter by sliding the power  
switch to its on position. Check the condition  
of the battery by looking at the LED below the  
power switch. The battery light should flash  
once and then go out. If the LED stays on, the  
battery is weak and should be replaced.  
3. Prepare the audio source by attaching the  
lavalier microphone to the user, placing the  
headset on the user’s head or plugging the  
cable into the instrument (depending on what  
type of system you have). Keep the audio  
muted while plugging in and adjusting the  
microphone or source.  
8. Clip the bodypack to the user’s belt or to a  
pocket. The bodypack can be positioned hori-  
zontally or vertically by moving the belt clip  
attachment. Removing the belt clip attach-  
ment screw and moving it 90 degrees will  
change the orientation.  
4. Check reception by observing that the RF  
carrier light is illuminated on the receiver’s  
front panel.

nent that contains digital circuitry including digital  
signal processors (reverb/multi-effects units),  
electronic keyboards, digital lighting controllers,  
CD players and computers all emit rf energy that  
can affect the performance of your wireless sys-  
tem. It is always best to place your receiver as far  
away from these devices as possible to minimize  
the potential for of problems.  
COMPATIBILITY  
The receiver and transmitter must be tuned to the  
same VHF frequency to operate together. Be-  
cause of the specialized equipment required to  
adjust these units properly, users cannot change  
frequencies.  
If two or more R100 and/or other VHF/UHF wire-  
less systems are being used in the same location,  
proper frequency coordination is required to avoid  
interference. Frequency mixing and spacing must  
be factored along with local TV stations to deter-  
mine if conflicts will result from a specific group.  
Contact your dealer or Electro-Voice for fre-  
quency-selection assistance if you are planning to  
add more wireless systems to be operated simul-  
taneously in the same location.  
BATTERY RECOMMENDATIONS  
Fresh 9-volt alkaline batteries from a quality  
manufacturer will yield the best performance from  
R100 transmitters. 8.4-volt ni-cad batteries can be  
used but will yield much shorter operational time.  
When the transmitter switch is turned on, the bat-  
tery light will flash one time if the battery is good.  
If the light does not flash or stays lit continuously,  
the battery is weak or nearly dead. If the light  
comes on during use, the battery is weakening  
and should be replaced as soon as possible.  
POTENTIAL SOURCES OF INTERFERENCE  
There are many potential sources of interference  
for your wireless system. Any electronic compo-
