DESCRIPTION
The Electro-Voice R200 is a series of UHF wireless systems that combine EVs legendary quality, reliability and high value. The R200 Series transmitters and receivers operate in the UHF frequency range between 710.100 and 721.350 MHz
(channels 54-55 in the TV band) on single frequencies. The well-designed audio circuitry ensures excellent signal-to-noise ratio with accurate sound quality.
SECURE-PHASE tm DIVERSITY
The R200 Series receivers utilize patented Secure-Phase tm diversity circuitry that provides the strongest, cleanest signal possible. Unlike other diversity circuits that switch antennas, Secure-
Phase tm utilizes the signal from both antennas at all times to increase signal strength, minimize dropouts and lower the potential for interference.
If the signal from the transmitter changes phase or polarity (a common cause of dropouts), the circuit adjusts the phase angle between the two antennas receiving circuits to prevent cancellation.

QUICK SETUP AND USE
To get your system into operation quickly, use the following instructions. Review the rest of the manual for additional setup and operational details.
1. Place the receiver where there is a clear line of sight to the area where the transmitter will be used (Figure 1). Extend the receivers antennas and separate them 90 degrees (see
Figure 2).
2. Make sure the sound systems volume is low or off on the input you intend to use for the wireless.
3. Plug in the receivers 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 local requirements.
4. Plug the audio cable (not supplied) into either output connector. The 3-pin XLR-type con-
Figure 1 nector is the preferred choice since the output is balanced. Either connector may be used with good results.
5. Turn the output level control (see Figure 2) on the front panel to the 12:00 oclock position
(midway in the controls range) if the ¼-inch connector is used (the 3-pin XLR-type connector has fixed level).
6. Setup and adjust the transmitter level as described on the following pages.
7. Turn up the level on the mixer or preamp to the desired setting.
8. Speak into the microphone or strum the instrument and, if necessary, adjust the receivers output until the volume level from the wireless system approximates the level of an equivalent wired microphone or instrument.
9. Walk the expected area of use to check for dropouts or interference. If problems occur, see the troubleshooting section.

HTU HANDHELD TRANSMITTER SETUP
1. Insert battery. Slide open the battery compartment cover by placing your thumb on the indents of the battery door (at the back end of the transmitter) and gently pull down (see Figure 3).
2. Turn on the transmitter by sliding the power switch (closest to the battery compartment) forward to its on position, toward the mic element. The red battery condition light should flash once and then go out. If the red LED stays on or illuminates during a performance, it should be replaced immediately. The green
LED will stay lit when the transmitter is on.
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 intended area of use and make sure that there are no barriers to reception or sources of interference.
page 4
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 or high, adjustments are necessary. Gently insert the provided screwdriver (or other 3/32-in. 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. Gently turn counterclockwise until the control stops (the mic output is attenuated but not off). Slowly turn the miclevel control while listening to the audio. If the audio becomes distorted, turn the mic level control counter-clockwise about 1/8 turn.
6. Adjust the squelch control if necessary.
The squelch control on the back of the receiver may be adjusted to increase range or reduce interference. Turn the control counter-
R200 OWNERS MANUAL clockwise to increase range. Caution! Increasing the range will make the system more susceptible to outside interference!
If the squelch is being adjusted, turn the
Figure 2 transmitter off. Turn the squelch control counter-clockwise until you hear noise or interference. Then, turn the squelch clockwise until the noise is gone.
BODYPACK TRANSMITTER SETUP
1. Insert battery. Open the hinged battery compartment 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 into the battery compartment first. Close the battery door by sliding the door shut.
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 red 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 users 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. Placement of lavalier and headset microphones will noticeably change the sound quality, so some experimentation with the user is necessary.

4. Check reception by observing that the RF carrier light is illuminated on the receivers front panel.
5. Turn on the audio transmission by sliding 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 located at the top edge of the battery compartment under the door. The door has to be opened but not swung upward to make adjustments. 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 control clockwise while listening to audio; if the audio becomes distorted, turn the mic level control counter-clockwise about 1/8 turn.
8. Clip the bodypack to the users belt or to a pocket. The bodypack can be positioned horizontally or vertically by moving the belt clip attachment. Removing the belt clip attachment screw and moving it 90 degrees will change the orientation.

R200 OWNERS MANUAL
COMPATIBILITY
The receiver and transmitter must be on the same
UHF frequency to operate together. Because of the specialized equipment required to adjust these units properly, users cannot change the frequencies or make any internal adjustments.
If two or more R200 and/or other VHF/UHF wireless systems are being used in the same location, proper frequency coordination is necessary to avoid interference. Frequency mixing and spacing must be factored along with local TV stations to determine if conflicts will result from a specific group. Contact your dealer or Electro-Voice for frequency-selection assistance if you are planning to add more wireless systems to be operated simultaneously in the same location.
POTENTIAL SOURCES OF INTERFERENCE
There are many potential sources of interference for your wireless system. Any electronic component 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 system. It is always best to place your receiver as far away from these devices as possible to minimize this potential source of problems.
BATTERY RECOMMENDATIONS
Fresh 9-volt alkaline batteries from a quality manufacturer will yield the best performance from
R200 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 battery 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 dead. If the light comes on during use, the battery is weakening and should be replaced as soon as possible.
