HTV Handheld Transmitter
• Electro-Voice MC500 cardioid dynamic micro-
phone transducer.
• Designed and manufactured in the United
States of America
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
R100 SERIES COMPONENTS
R100 Secure-Phasetm Diversity Receiver

• BGV: VHF guitar bodypack with hardwired
cable and ¼-inch connector with specially de-
signed audio circuitry to handle guitar tran-
sients
• Clean, undistorted sound reproduction using
proprietary compander circuitry
• Separate on/off and large mute switches for
operational flexibility
• Wide-range adjustable audio output via line
level ¼-inch connector
• LED battery condition indicator gives quick indi-
cation of battery strength
• May be rack mounted with optional kit

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.

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-
