This system offers all of the advantagesof wireless in-ear monitoring–mobility, more focused audio, freedom from feedback,and elimination of transport issues associated with conventional floor monitors–aswell as the longterm health benefits of safe listening levels. For the first time, awireless in-ear monitor system combines state-of-the-art advanced frequency-agilePLL synthesized UHF technology, high-end performance, ease of use, andunprecedented affordability. The PEM-500 offers a choice of 16 user selectable UHFchannels in both the transmitter and receiver(s), as well as stereo (MPX system) ormono mode transmission. This system is indispensable for live-stage musicperformance, and is loaded with features previously found only in units costingseveral times more.This booklet gives instructions for the operation of the PEM-500 Wireless In-EarMonitor System. Please read the instructions for your system completely beforeoperating unit. This manual first lists the features of the PEM-500, and then takesyou step-by-step in explaining how to operate your new system, both transmitterand receiver. Each section gives you detailed operating instructions. Also included inthis manual are system specifications and servicing information. INTRODUCTIONUSING THIS MANUAL3
242820215292324272218181819132625USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENTHEARING DAMAGE. ALWAYS USE AS LOW A VOLUME AS POSSIBLE.The Occupational Safety Health Administration (OSHA) has established thefollowing guidelines for maximum time exposure to sound pressure levels (SPL)before hearing damage occurs: 90 dB SPL @ 8 hours 95 dB SPL @ 4 hours 100 dB SPL @ 2 hours 105 dB SPL @ 1 hour 110 dB SPL @ 1/2 hour 115 dB SPL @ 15 minutes Aviod exposure to 120 dB or greater SPL or irreversible ear damage may result.(Note: It is difficult to measure the SPL present at the eardrum in live soundapplications. The volume present will be affected by the level setting of your PEM-500R, the ambient stage sound from your other instruments and speakers, and thequality of and fit of your in-ear speakers.) Always avoid prolonged listening at excessive sound pressure levels. Use thefollowing guidelines to use this system safely:1.Turn up the volume to your earphones only enough to hear properly. The PEM-500 can provide a high quality monitor mix at significantly lower decibellevels than floor monitors. Whenever possible, use the system with the limiterin the PEM-500R receiver ON.2. Just as with any in-ear monitor system, The PEM-500 works best when used exclusively by all performers on stage (without any wedges or side monitors).The high sound pressure levels produced by floor monitors (especially if theband plays loud) can bleed through the in-ear monitor earbuds and, in theworst cases, hinder their effectiveness. Experiment with your overall mix to getthe maximum benefit from your PEM-500.3. Turn down the volume immediately if you experience any pain or hearingdiscomfort or ringing in the ears after use.4. Have an audiologist check your hearing and ears regularly. If you experienceany wax buildup in your ears, do not use the system until an audiologistexamines your ears.5. Wipe the earphones with an antiseptic before and after use to avoidinfection. Stop using the earphones if they cause discomfort or infection.WARNING4An equilateral triangle enclosing an exclamation pointis intended to alert the user to the presence of importantoperating and service instructions in the literatureenclosed with this unit.!
6. Attaching the ReceiverThe PEM-500R can be slipped into a pocket or clipped onto clothes or a belt withthe BELT CLIP (27). Note that for utmost versatility and convenience, this clip can berotated 90˚ for attaching receiver either vertically or horizontally on clothes or beltas desired. To rotate clip, loosen the Phillips screw holding the clip, change theposition as needed, and retighten the screw to secure the clip.7. Adjusting Ear Monitor VolumeAfter the PEM-500T transmitter has been adjusted to optimum volume and Stereo orMono reception is selected simultaneously on both the transmitter and receiver asper the preceding instructions, the received volume can be adjusted as desired.Select the volume with the thumbwheel VOLUME CONTROL (28). As per thepreceding WARNING section, turn up the VOLUME CONTROL only far enough tohear properly. For longterm ear safety, it is highly recommended that you alwaysselect the volume limiting provided by the LIMITER ON/OFF SWITCH (29) in theBATTERY COMPARTMENT. (Note: Ringing in the ears after use indicates the gain levels you have selected maybe too high. Either select LIMITER ON or turn down the VOLUME CONTROL. Youmay also need to lower the overall volume of the band instruments and amplifiers toenable more comfortable and safer listening levels. See the WARNING section,pg.4) 8. Testing Receiver Range Wearing your receiver and earphones, walk around the stage area and listen foraudio quality. Depending on room size, obstructions, amount of reflective metalsurfaces, and other conditions that may affect RF transmission, it is normal that theaudio may disappear or "drop out" in certain locations. Such zones, otherwiseknown as "null spots" are very small and fixed in location if you are within 100 feetof the transmitter, and will become larger as you approach the ultimate range ofyour system in that location (up to 300 or so feet, depending on site conditions).Generally, it is possible to eliminate such "null spots" by moving your PEM-500Ttransmitter as little as 12-18 inches in any direction. If that is not convenient (e.g.,because the PEM-500T is rackmounted), you can also use an optional remoteantenna. Contact the NADY SYSTEMS Service Department (see pg.15) forinformation about remote antennas for the PEM-500T. After you move thetransmitter or relocate a remote antenna, range walk the stage and other areas youwill use in your performance to again check for consistent reception. You are nowready to use the PEM-500 system for wireless personal in-ear monitoring.(Note: Due to the strong transmission power of the PEM-500T, you may experiencecompromised audio or static if the PEM-500R is too close to the antenna of thePEM-500T transmitter. Always operate the receiver at least 6 ft (2 m) away from thetransmitter antenna.)12• Available on selected frequency bands within the UHF band for interference-free, long-range performance (up to 8 systems can be operatedsimultaneously, depending on country and frequency band)• System consists of PEM-500T transmitter and one bodypack PEM-500Rreceiver, both of which offer 16 channel user selectability. Any number ofadditional receivers can also be operated with the same transmitter if they areall set to the same channel. • Proprietary companding circuitry for wide Dynamic Range and clear, naturalsound • Operating Range: Up to 300 feet typical (depending on site conditions)• Rugged, foam-padded traveling case provides easy, safe transport andstoragePEM-500T Transmitter• Rugged, all metal half-rack that can be rackmounted singly or side-by-sidewith optional rack kits• Microphone input allows wireless cueing of performers on stage• Front panel features input level control, stereo headphone monitor output jackand volume control, select button for choosing one of 16 UHF channels, LEDchannel display, and Left/Right 10-segment audio input level displays.• Back panel provides BNC jack for the detachable antenna, a Stereo/Monoselect switch, a 1/4" TRS balanced microphone input, and XLR jacks for Leftand Right Line inputs.• Externally powered by AC/DC power adapterPEM-500R Receiver• Portable bodypack receiver features a power switch, switchable built-in volumelimiter, output level control, stereo/mono select switch, and two-color(red/green) 3-way unit ON/Signal/Low Battery LED indicator.• Operates up to 6 hours (depending on volume) on a 9V alkaline battery• Each receiver is supplied with a pair of miniature, lightweight (yet powerful)in-ear speakers with soft rubber mounts in 3 sizes (small, medium, and large)designed for "custom" form-fitted comfort and optimum acoustic transfer andisolation.• Rear clip can be rotated 90˚ for attaching receiver either vertically orhorizontally to clothes.SYSTEM FEATURES5
4. Selecting Stereo or Mono Mode ReceptionSwitch the STEREO/MONO CONTROL (23) in the BATTERY COMPARTMENT tostereo or mono reception to match the transmission mode already selected for thetransmitter, as per the Connecting the Audio Input section of the PEM-500Ttransmitter instructions above. You can also try different combinations for differentapplications. For example, if multiple PEM-500R receivers are being used with onePEM-500T transmitting in stereo, the different performers may select either a stereomix with the STEREO/MONO CONTROL (which may feature vocals on one side andthe rest of the mix on the other), or a mono mix (with the vocals and music mixedtogether). Such capability adds to the versatility of the system by allowing morepersonal control of the individual sound received by different performers all listeningto the same transmitted mix. 5. Connecting the In-Ear Monitor Speakers The PEM-500R is provided with a 3.5 mm TRS STEREO EARPHONE MINI JACK (24)for connecting the EARBUD SPEAKERS (25) supplied. These miniature in-earspeakers can be inserted in the ear with the foam screens supplied as standardportable sound system earphones. For better isolation from ambient stage soundsand a more secure fit, 3 sets of soft "form-fit" RUBBER IN-EAR MOUNTS (26) areprovided to fit all sizes (small, medium and large). Select the size that best fits inyour ears most comfortably. Remove the foam screen from the earphones and slipthe RUBBER MOUNTS over each speaker. Insert the MOUNTS (with speakers), onein each ear. (Note: Wipe the earphones and rubber mounts with an antiseptic before and aftereach use to avoid infection. Stop using the earphones if they are causing discomfortor infection.)[Note: For best results and sound, a pair of custom-fitted ear transducers, suppliedwith soft rubber mounts cast by an audiologist from your own ear cavity, arerecommended. Although expensive, these earphones will provide the most natural,full frequency response, best acoustic isolation and longest-term wearing comfort.Such units can be ordered from suppliers such as Sensaphonics(www.sensaphonics.com) and Ultimate Ears (www.ultimateears.com). Contact one ofthese suppliers directly for more information on their custom earphones.] 11PEM-500T TRANSMITTER 1. Rackmounting the transmitterThe PEM-500T requires no installation and can be used on any flat surface.However, in some applications rack mounting is preferred. There are 2 optionsavailable for rackmounting the PEM-500T transmitter: singly or side-by-side withanother PEM-500T transmitter. • Single mounting: The PEM-500T is supplied with RE-5 RACK EARS (1) whichcan be attached with the screws provided on the front of the side panels toenable rackmounting the receiver.• Side-by-side dual mounting: Two PEM-500T transmitters can be rackmountedside-by-side using the optional RKT-25 RACK KIT TRAY (2) which holds 2transmitters. (Note: Do not mount the transmitter(s) in a rack directly above an amplifier or othersource of high heat–this could degrade the performance of the PEM-500T. Alwaysensure adequate airflow and heat dissipation in any rack configuration.)2. Powering the TransmitterPlug the 12V AC/DC ADAPTER (3) provided into the DC INPUT JACK (4) on theback of the receiver. Then plug the power supply into an AC outlet. (Note: Any 12-15V DC source with 500mA capability can also be used.) Press thePOWER SWITCH (5) once to turn on the transmitter. The POWER ON LED (6) willnow light and the transmitter is operational.3. AntennaConnect the front panel TELESCOPIC ANTENNA (7) or optional remote antenna tothe ANTENNA JACK (8). Extend the antenna fully to obtain maximum range.Optimal antenna position is vertical. For maximum range, it is always best tomaintain a line of sight (no obstructions) between the transmitter antenna and thereceiver(s) at all times whenever possible.OPERATION6
PEM-500R RECEIVER1. Multiple Monitor MixesAny number of PEM-500R receivers can be used with a single PEM-500T transmitterset to the same channel. Although there are individual controls on each receiverallowing different levels of volume, each receiver will receive the same transmittedmonitor mix (see Selecting Stereo or Mono Mode Reception below for exceptions).If different mixes are required for the different performers, additional PEM-500Ttransmitters and receivers set to other channels must also be used, and eachtransmitter must be fed a different mix from the console as desired. (Note: Never set more than ONE transmitter to the same operating frequency.) 2. Powering the Receiver(s)Slide down and flip open the BATTERY COMPARTMENT (18) and insert a fresh 9VBATTERY (19), observing the correct polarity. Turn on the receiver with the POWERSWITCH (20). If the battery has usable strength, the 2 color UNIT ON/SIGNAL/LOW BATTERY LED (21) will glow red if the transmitter is OFF and green if it is onand tuned to the same channel as the receiver. The battery should last up to 6hours, depending on the music content and volume, but it is recommended that it bechanged every 3-4 hours if possible. If the battery is too weak for operation, theLED will not light at all or flash alternate green/red if the transmitter is turned on,and on the same channel, or flash red if the transmitter is turned off. If this occursduring use, immediately change the battery to ensure optimum continuingperformance.3. Selecting the ChannelInside the open BATTERY COMPARTMENT, use a small screwdriver and adjust theCHANNEL SELECTOR CONTROL (22) to the same channel as selected above for thetransmitter with which you will use this receiver. The UNIT ON/SIGNAL/LOWBATTERY LED will change from red to green when the same channel is selected,indicating reception of the signal from the associated PEM-500T transmitter.104. Connecting the Audio InputThe PEM-500T transmitter features a 1/4" TRS balanced MIC INPUT (9) and a linelevel balanced XLR jack for the LEFT and RIGHT LINE INPUTS (10). The MIC INPUTallows the use of a microphone alone for easy cueing of performers while on stage,which can be useful in many applications. It can be used even with input signalsalso connected to the LINE INPUTS. Select the input jack appropriate for thesignal(s) you are feeding to the transmitter: A. For a microphone input, plug a balanced 1/4" TRS or an unbalanced 1/4"TS cable from a dynamic microphone into the MIC INPUT. B. Stereo monitor mixes from your console can be connected to the LEFT andRIGHT LINE INPUTS with balanced XLR connectors. Mono monitor mixes canalso be input in this manner. Select STEREO for stereo inputs and MONO formono inputs, as appropriate, with the STEREO/MONO SWITCH (11). Monosignals are transmitted on both the left and right channels equally with thevolume adjustable by the AUDIO LEVEL CONTROL (12). The gain of stereosignals can be further adjusted separately (L/R) by the console monitor feed.With the STEREO/MONO SWITCH set to MONO, a stereo input signal willbe transmitted as mono. If the switch is set to STEREO, a mono signal will stillbe transmitted as mono. If a signal is input only to one of either the left orright LINE INPUTS and the switch is set to STEREO, it will only be transmittedon that side. However, if the switch is then set to MONO, it will betransmitted on both sides as a MONO signal. See also Selecting Stereo orMono Operation in the PEM-500R Receiver section. (Note: As when making any connection, make sure that the PEM-500T AUDIOLEVEL CONTROL and the console output levels are set at minimum volume beforeplugging into the transmitter. This will avoid possible loud transients in the PEM-500R receiver if it is already turned on, and with earphones plugged into theuser’s ears.)7OPERATION

Select an open frequency that doesn't interfere with anyother PEM-500 or UHF wireless mic system you are also using by pushing theCHANNEL SELECT BUTTON (13) on the front panel of the PEM-500T until thechannel you want is displayed on the CHANNEL LED DISPLAY (14). You will alsoneed to select the same channel for the transmitter (see Transmitter Operationinstructions above). If different mixes are required for the different performers,additional PEM-500T transmitters and receivers set to other channels must also beused, and each transmitter must be fed a different mix from the console as desired.Depending on the band(s) you are using and open channel availability within theband(s), up to 8 PEM-500 systems on different frequencies can be operatedsimultaneously to provide multiple discrete mixes to the performers.(Note: Never set more than ONE transmitter to the same operating frequency)[Note: After selecting a frequency on the transmitter, you must also check with thereceiver to ensure that the chosen channel is open (i.e., no other transmissions fromother sources, such as UHF TV channels in your area, operating at the samefrequency). Turn off the PEM-500T transmitter, and monitor the signal from the PEM-500R (see PEM-500R instructions, pg. 10). It should be silent. For optimumoperation and range, if you receive any transmissions or static you must chooseanother channel that is clear.][Note: If, after you complete the set-up, you experience interference orunsatisfactory audio performance, change the channel until the problem goes away.In the extremely rare circumstance that such a problem persists, turn off all UHFwireless mics being used or move their receivers physically away from the PEM-500T transmitter. In some instances, UHF wireless mics and the PEM-500 system caninteract if they are too close in frequency. Contact the NADY SYSTEMS ServiceDepartment for further information if necessary (see SERVICE, pg.15)]6. Adjusting Levels Adjust the selected audio input level for optimum level for transmission with theLEVEL CONTROL (12). Adjust the control so that the top LEDs on the 10-segment Leftand Right LED LEVEL DISPLAYS (15) light intermittently only on loud peaks. Thiscontrol adjusts both the left and right signals simultaneously in the same manner. Foradded control and separate levels on stereo inputs, use the left and right stereomonitor output level control on your console providing the signal.7.Headphone MonitoringThe sound technician can monitor the signal being transmitted with a wired pair ofheadphones via the stereo 1/4" TRS MONITOR OUTPUT JACK (16). The volumecan be adjusted as desired with the HEADPHONES VOLUME CONTROL (17). Boththe left and right channels of a stereo signal are adjusted simultaneously by thiscontrol in the same manner. 8

For longterm ear safety, it is highly recommended that you alwaysselect the volume limiting provided by the LIMITER ON/OFF SWITCH (29) in theBATTERY COMPARTMENT. (Note: Ringing in the ears after use indicates the gain levels you have selected maybe too high. Either select LIMITER ON or turn down the VOLUME CONTROL. Youmay also need to lower the overall volume of the band instruments and amplifiers toenable more comfortable and safer listening levels. See the WARNING section,pg.4) 8. Testing Receiver Range Wearing your receiver and earphones, walk around the stage area and listen foraudio quality. Depending on room size, obstructions, amount of reflective metalsurfaces, and other conditions that may affect RF transmission, it is normal that theaudio may disappear or "drop out" in certain locations. Such zones, otherwiseknown as "null spots" are very small and fixed in location if you are within 100 feetof the transmitter, and will become larger as you approach the ultimate range ofyour system in that location (up to 300 or so feet, depending on site conditions).Generally, it is possible to eliminate such "null spots" by moving your PEM-500Ttransmitter as little as 12-18 inches in any direction. If that is not convenient (e.g.,because the PEM-500T is rackmounted), you can also use an optional remoteantenna. Contact the NADY SYSTEMS Service Department (see pg.15) forinformation about remote antennas for the PEM-500T. After you move thetransmitter or relocate a remote antenna, range walk the stage and other areas youwill use in your performance to again check for consistent reception. You are nowready to use the PEM-500 system for wireless personal in-ear monitoring.(Note: Due to the strong transmission power of the PEM-500T, you may experiencecompromised audio or static if the PEM-500R is too close to the antenna of thePEM-500T transmitter. Always operate the receiver at least 6 ft (2 m) away from thetransmitter antenna.)12• Available on selected frequency bands within the UHF band for interference-free, long-range performance (up to 8 systems can be operatedsimultaneously, depending on country and frequency band)• System consists of PEM-500T transmitter and one bodypack PEM-500Rreceiver, both of which offer 16 channel user selectability.

242820215292324272218181819132625USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENTHEARING DAMAGE. ALWAYS USE AS LOW A VOLUME AS POSSIBLE.The Occupational Safety Health Administration (OSHA) has established thefollowing guidelines for maximum time exposure to sound pressure levels (SPL)before hearing damage occurs: 90 dB SPL @ 8 hours 95 dB SPL @ 4 hours 100 dB SPL @ 2 hours 105 dB SPL @ 1 hour 110 dB SPL @ 1/2 hour 115 dB SPL @ 15 minutes Aviod exposure to 120 dB or greater SPL or irreversible ear damage may result.(Note: It is difficult to measure the SPL present at the eardrum in live soundapplications. The volume present will be affected by the level setting of your PEM-500R, the ambient stage sound from your other instruments and speakers, and thequality of and fit of your in-ear speakers.) Always avoid prolonged listening at excessive sound pressure levels. Use thefollowing guidelines to use this system safely:1.Turn up the volume to your earphones only enough to hear properly. The PEM-500 can provide a high quality monitor mix at significantly lower decibellevels than floor monitors. Whenever possible, use the system with the limiterin the PEM-500R receiver ON.2. Just as with any in-ear monitor system, The PEM-500 works best when used exclusively by all performers on stage (without any wedges or side monitors).The high sound pressure levels produced by floor monitors (especially if theband plays loud) can bleed through the in-ear monitor earbuds and, in theworst cases, hinder their effectiveness. Experiment with your overall mix to getthe maximum benefit from your PEM-500.3. Turn down the volume immediately if you experience any pain or hearingdiscomfort or ringing in the ears after use.4. Have an audiologist check your hearing and ears regularly. If you experienceany wax buildup in your ears, do not use the system until an audiologistexamines your ears.5. Wipe the earphones with an antiseptic before and after use to avoidinfection. Stop using the earphones if they cause discomfort or infection.WARNING4An equilateral triangle enclosing an exclamation pointis intended to alert the user to the presence of importantoperating and service instructions in the literatureenclosed with this unit.!
