INTRODUCTION  
Thank you for purchasing a PEAVEY PV®-1 UHF Diversity Wireless Microphone  
System. The PV-1 UHF wireless systems have user friendly features and are  
available in handheld, lavalier, headset and guitar models.  
Clear channel UHF operation in three available frequencies.  
The proprietary compander circuitry yields a dynamic range of up to  
120dB  
Squelch control for locking out potential interference. Choice of  
Transmitters:  
Bodypack with input level control.  
Handheld microphone is equipped with a neodymium cartridge  
that delivers high quality audio reproduction, minimal handling  
noise and enhanced feedback rejection.  
Diversity reeiver allows for maximum reception range and dropout  
protection, full LED indicators, both ¼” unbalanced and XLR balanced  
outputs, and special circuitry for noiseless transmitter ON/OFF switching.  
IMPORTANT SAFEGAURDS  
CAUTION!  
1) DO NOT attempt to make internal adjustments to the system. Please refer al servicing  
to your authorized Peavey Service Center.  
2) Turn the unit off if it is exposed to excessive moisture while in operation. Allow unit to dry  
thoroughly, then power back up. If unit fails to power up, then refer unit to your authorized  
Peavey Service Center.  
WARNING! Risk of injury or death if used improperly  
DURING INSTALLATION AND SET UP  
To reduce the risk of shock DO NOT handle AC/DC adapter with wet hands.  
To reduce the risks of fire or shock from damaged power cord always remove cord from  
outlet by grasping the adapter tightly while unplugging.  
To reduce the risk of fire or shock from damaged power cord always turn unit off before  
3
 
moving it.  
To reduce the risk of fire or shock DO NOT expose this equipment to moisture or dust.  
To reduce the risk of fire or shock use only with specified voltage.  
To reduce the risk of fire or shock DO NOT damage the power cord by placing it near a heat  
source or stacking heavy items on top of it.  
To prevent damage to unit DO NOT place on surface that is unstable or that can tip over.  
DURING OPERATION  
To reduce the risk of fire or shock DO NOT remove the chassis cover. There are no user-  
serviceable parts inside. For all repairs refer unit to your authorized Peavey Service Center.  
To reduce the risk of fire or shock DO NOT place water or metal items on top of unit.  
To reduce the risk of fire or shock DO NOT allow metal, liquids or flammable items fall into unit.  
To reduce the risk of fire or shock DO NOT touch AC outlet during thunderstorms.  
To prevent injury DO NOT place heavy items on top of unit.  
Clear the dust out from the inside regularly. Accumulated dust can create a fire hazard  
as well as damage to the equipment.  
Clear the dust out from plug and AC outlet. Again this accumulated dust can create a fire  
hazard.  
Make sure the AC/DC adapter is plugged in entirely. No exposed metal.  
When not in use for long periods of time, turn unit off and remove the AC adapter.  
UHF RECEIVER  
1.  
Powering the receiver  
Plug the 12V AC/DC ADAPTER provided into the DC INPUT JACK on the back of the  
receiver. Then plug the power supply into an AC outlet. (Note: Any DC source with 500mA  
capability can also be used.) Press the POWER SWITCH (1) once to turn on the receiver. The  
POWER ON LED (1) will now light and the receiver is operational.  
2.  
Antennas  
Extend ANTENNAS (5) fully to obtain maximum range. Optimal antenna position is 45 degrees  
from the receiver (at 90 degrees from each other).

3.  
Squelch Adjustment  
In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise to the factory  
preset RF level (Max. Sens.). However, in areas of high RF activity, the squelch (or mute, as it is  
sometimes called) may need to be adjusted to compensate for the adverse conditions in a  
particular location. If, with the transmitter off, the receiver’s A and/or B DIVERSITY LED  
INDICTORS (3) flicker or stay on, the squelch control should be turned counterclockwise until the  
A and/or B LEDs extinguish.  
When the squelch is properly adjusted, the A and/or B LEDs will only light when the system  
transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the  
range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater  
than 75 feet, one or the other of the A or B LEDs may extinguish briefly. This is normal – the  
unit’s Diversity reception ensures that the received audio will not be interrupted. When both  
LEDs extinguish, the transmitter is out of range for that given location, and the user should move  
closer to the receiver to re-establish the radio link.

Connecting the Audio Output  
The UHF receiver provides both a fixed mic level BALANCED MIC AUDIO OUTPUT XLR (7) and  
an adjustable line level AUX AUDIO OUTPUT ¼” JACK (9).  
[Note: As when making any connection, make sure the amplifier or mixing board volume is at the  
minimum level before plugging in the receiver to avoid possible sound system damage.]  
INSTRUMENT CONNECTION  
Insert an audio cord with a ¼” mono phone plug in the AUX AUDIO OUTPUT JACK (9) on the  
rear panel of the receiver. Plug the other end of the cord into an amplifier, effects, or mixing  
board, Adjust the AUX VOLUME CONTROL (8) on the UHF receiver clockwise until the volume  
level is comfortable for your application. This setting is roughly equivalent to a direct instrument  
cord connection.  
Microphone connection (using the transmitter with either a headset or lavalier microphone or the  
handheld microphone transmitter)  
For Microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (7) or the ¼” line level  
AUX AUDIO OUTPUT (9) can be used. The XLR output is set at a nonadjustable microphone  
level, similar to wired mic levels. Plug an XLR connector into the XLR output connector on the  
rear of the unit and plug the other end into your amplifier or mixing board.  
Make sure the volume is turned down when making connections. For your convenience, the XLR  
output level is preset at the factory and is not adjustable with the receiver volume control.  
The receiver is equipped with an AF PEAK LED INDICATOR (3) which lights with a strong audio  
signal from the transmitter. Occasional flickering on loud inputs to the transmitter is normal. If  
the LED lights continuously, decrease the volume to the transmitter or overload distortion may  
result.  
HANDHELD MICROPHONE  
1.  
2.  
Unscrew the BATTERY COMPARTMENT COVER (13) and remove, exposing the BATTERY  
HOLDER (14). Insert a fresh 9V ALKALINE BATTERY (15), observing the correct polarity as  
marked, and screw the cover back on to the microphone. Make sure the cover is screwed on  
completely. A fresh alkaline battery can last up to 10 hours in use, but in order to ensure  
optimum performance, it is recommended that you replace the battery after every 7-8 hours of  
use.  
Turn on the microphone by sliding the OFF/STANDBY/ON SWITCH (16) to the STANDBY  
position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The  
BATTERY INDICATOR LED will give a single quick flash, indicating usable battery strength.  
In the case of a dead or low battery, the LED will either not illuminate at all or will stay on  
continuously, indicating that the battery should be replaced.

3.  
The microphone is now ready to use. The A and/or B DIVERSITY LED INDICATORS (2) on the  
receiver should now be lit, indicating a received signal from the transmitter. When ready to  
speak, slide the transmitter switch to the ON position. Adjust the volume of the receiver as per the  
Audio Output Microphone Connection section of the above receiver instructions.  
[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that  
acoustic feedback will be avoided.]  
*To preserve battery life, turn the transmitter off when not in use.  
BODYPACK TRANSMITTER  
1.  
2.  
Slide open the hinged BATTERY COMPARTMENT (18) and insert (2) fresh AA ALKALINE  
BATTERIES (19), observing the correct polarity. Fresh alkaline batteries can last up to 10 hours  
in use, but in order to ensure optimum performance, it is recommended that the battery be  
replaced after 7-8 hours of use.  
The body pack is equipped with a 3.5mm LOCKING JACK (21) for connecting the audio input  
selected. Connect either the INSTRUMENT CORD (22) or the HEADSET MIC (23) or LAVALIER  
7
 
MIC CORD (24) as desired. To secure the connection, insert locking mini-XLR into the jack. To  
unplug, reverse the process.  
Slip the transmitter into a pocket or CLIP (28) it on to your clothes or instrument strap (if using it  
as an instrument transmitter). The CLIP can be rotated 90 degree if the transmitter is to be  
attached horizontally (instead of vertically) by loosening the screws holding the clip.  
3.  
Turn on the body pack transmitter by sliding the OFF/STANDBY/ON SWITCH (26) to the  
STANBY position (transmitter on, audio mute or the ON position (transmitter and audio both on).  
The BATTERY INDICATOR LED (25) will give a single quick flash, indicating usable battery  
strength.  
In the case of a dead or low battery, the LED either will not illuminate at all or will stay on  
continuously, indicating that the battery should be replaced. To preserve battery life, turn the  
transmitter off when not in use. The transmitter is now ready to use. The A and/or B  
DIVERSITY LED INDICATORS (2) on the receiver should now be lit, indicating a received signal  
from the transmitter.  
4.  
Instrument Use  
Plug the ¼” phone plug from the INSTRUMENT CORD (22) into the instrument. As the cord to  
the instrument also serves as the antenna, be sure to extend if fully for maximum range. Rolling  
up or shortening the cord may reduce the effective operating range. When ready to play, slide  
the audio OFF/STANDBY/ON SWITCH (26) to the ON position. Adjust the volume of the receiver  
as per the audio Output Instrument Connections section of the above UHF receiver instructions.  
(Note: Levels should be adjusted with the volume control of your instrument.)  
The AF PEAK LED INDICTOR (3) on the UHF receiver will light for all loud input signals.  
Occasional flickering on and off during use is normal, however if the LED stays on continuously,  
turn down the instrument volume or noticeable distortion may result.  
(Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or  
connections are used with any wireless system. Therefore, the supplied INSTRUMENT CORD  
(22) has a factory installed capacitor inside the ¼” plug. This capacitor provides first order  
filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises.  
Should your equipment still give you scratchy noises, we suggest these steps to eliminate them:  
a)  
b)  
Make sure all guitar volume and tone pots are clean and all contacts are soldered, this is  
very important.  
A 47pf capacitor soldered across the hot to ground terminals of the guitar’s volume and  
tone pots will provide extra filtering.  
5.  
Microphone Use (with either a lavalier or headset microphone)  
Secure the connection from the LAVALIER (24) or HEADSET MIC CORD (23), to secure the  
connection, insert locking mini-XLR into the jack. To unplug, reverse the process.  
8
 
To use the lavalier mic, attach it at chest level or higher. Do not place it too close to the mouth –  
a distance of about six inches is recommended. To use the headset mic, place it on your head  
and adjust the boom so that the mic is about one inch to the side of the front of the mouth. As the  
microphone cord also serves as the antenna, be sure to extend it fully. Rolling up or shortening  
the cord may reduce the effective operating range – keep it as straight as possible.  
When ready to speak, slide the OFF/STANDBY/ON SWITCH (26) to the ON position. Adjust the  
volume of the receiver as per the Audio Output Microphone Connection section of the above UHF  
receiver instructions.  
[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that  
acoustic feedback will be avoided. Unidirectional mics are more resistant to feedback, but pick  
up sound equally from all directions, and are prone to feedback if not used carefully.  
Unidirectional mics are more resistant to feedback, but pick up sound sources best that are  
directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers,  
require more acoustic gain and thus more prone to feedback than close-source mics such as  
handheld or headset models that are used close to the mouth.  
The AF PEAK LED INDICTOR (3) on the UHF receiver will light for all loud input signals.
