Introduction
Thank you for purchasing a Nady PEM-1000 Wireless Personal In-Ear Monitor System and
congratulations on your choice. This PEM-1000 offers all of the advantages of wireless
in-ear monitoring–mobility, more focused audio, freedom from feedback, and elimination
of transport issues associated with conventional floor monitors–as well as the long-term
health benefits of safe listening levels. For the first time, a wireless in-ear monitor system
combines state-of-the-art advanced frequency synthesized UHF technology, high-end
performance, ease of use, and unprecedented affordability. The PEM-1000 offers a choice
of 100 user selectable UHF channels for the transmitter and receiver(s), as well as stereo
(MPX system) or mono mode transmission. This system is indispensable for live-stage
music performance, and is loaded with features previously found only in units costing
several times more.
Using This Manual
This booklet gives instructions for the operation of the PEM-1000 Wireless In-Ear Monitor
System. Please read the instructions for your system completely before operating unit.
This manual first lists the features of the PEM-1000, and then takes you step-by-step
in explaining how to operate your new system, for the transmitter and receiver(s). Each
section gives you detailed operating instructions. Also included in this manual are system
specifications and servicing information.
Warning
USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.
ALWAYS USE A VOLUME LEVEL AS LOW AS POSSIBLE.
The Occupational Safety Health Administration (OSHA) has established the following 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
Avoid exposure to 120 dB SPL or greater or irreversible ear damage may result.
(Note: It is difficult to measure the SPL present at the eardrum in live sound applications. The volume
present will be affected by the level setting of your PEM-1000R, the ambient stage sound from your
other instruments and speakers, and the quality of and fit of your in-ear speakers.)
Always avoid prolonged listening at excessive sound pressure levels. Use the following guidelines to use
this system safely:
1. Turn up the volume to your earphones only enough to hear properly. The PEM-1000 can provide a high
quality monitor mix at significantly lower decibel levels than floor monitors. Whenever possible, use
the system with the limiter in the PEM-1000R receiver ON.
2. Just as with any in-ear monitor system, The PEM-1000 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 the band plays loud) can bleed through the in-ear monitor ear-buds and,
in the worst cases, hinder their effectiveness. Experiment with your overall mix to get the maximum
benefit from your PEM-1000.
3. Turn down the volume immediately if you experience any pain or hearing discomfort or ringing in the
ears after use.
4. Have an audiologist check your hearing and ears regularly. If you experience any wax buildup in your
ears, do not use the system until an audiologist examines your ears.
5. Wipe the earphones with an antiseptic before and after use to avoid infection. Stop using the
earphones if they cause discomfort or infection.
An equilateral triangle enclosing an exclamation point is intended to alert the users to
the presence of important operating and service instructions in the literature enclosed
with this unit.

Operation
PEM-1000T Transmitter
1. Rack-mounting the transmitter
The PEM-1000T requires no installation and can be used on any flat surface. However, in some applications rack
mounting is preferred. There are 2 options available for rack-mounting the PEM-1000T transmitter: singly or
side-by-side with another PEM-1000T transmitter.
• Single mounting: The optional RKT-11 Rack Kit (32) can be attached with the screws provided on the
front of the side panels to enable rackmounting a single PEM-1000T transmitter. Includes front antenna
mount, jack and connecting cable.
• Side-by-side dual mounting: The optional RKT-21 Rack Kit (33) can be attached with the screws
provided on the front of the side panels to enable rackmounting two PEM-1000T transmitters.
(Note: Do not mount the transmitter(s) in a rack directly above an amplifier or other source of high heat–this
could degrade the performance of the PEM-1000T. Always ensure adequate airflow and heat dissipation in any
rack configuration.)
2. Antenna
Connect the Antenna (35) or optional remote antenna on the back panel to the Antenna Jack (11). Optimal
antenna position is vertical. For maximum range, it is always best to maintain a line of sight (no obstructions)
between the transmitter antenna and the receiver(s) at all times whenever possible.
3. Powering the Transmitter
Plug the 12V-15V/1000mA DC Adapter (34) provided into the DC Input Jack (16) on the back of the receiver.
Then plug the power supply into an AC outlet. Press the Power Switch (10) once to turn on the transmitter. The
backlight LCD Display (4) will now light and the transmitter is operational. The LCD display will be lit up and
meantime all the relative information will be displaying on the screen, when the PLL circuit has been locked the
transmitter will start to transmit the signal.
4. Connecting the Audio Input
The PEM-1000T transmitter features a 1/4” TRS unbalanced and balanced XLR for the LEFT Input (14) and
RIGHT Input (15) combo sockets for inputting Line Level. The pass through LEFT and RIGHT output 1/4” TRS
unbalanced for daisy chain audio. The audio signal input can be chosen to be stereo or mono signal. If mono, the
input should be gone through AF IN RIGHT input (15) using XLR balanced input or 1/4” unbalanced plug, the
socket is a combo socket to be able to use the both plugs but only one a time.
(Please note: The signal input level is line level, if need to input Mic level, then it has to be amplified before
inputting, otherwise the sensitivity is not enough, we recommend to first connect with the monitoring output on
the mixer first.)
5. Set the proper audio input level
The strength of the audio input signal will be displaying on the two LED Indicators (3) on the front-left panel.
Adjusting the output level properly makes three LEDs to be lit up. When input level is higher, the four LEDs lit up.
If more than 4 LEDs are lit up the fifth red LED will be lighted to show the input signal has been too strong. So,
adjust the input properly to make sure the S/N ratio and dynamic range are the best to avoid distortion.
(Note: As when making any connection, make sure that the PEM-1000T Volume Knob (2) and the console
output levels are set at minimum volume before plugging into the transmitter. This will avoid possible loud
transients in the PEM-1000R receiver if it is already turned on, and with earphones plugged into the user’s ears.)
6. Monitoring on audio signal and connection with earphones
The sound technician can monitor the signal being transmitted with a pair of wired headphones via the stereo
1/4” TRS Earphone Output Jack (1). The volume can be adjusted as desired with the Volume Knob (2). Both
the left and right channels of a stereo signal are adjusted simultaneously by this control in the same manner. To
monitor the sound, plug the stereo earphones into the earphone/headphone output jack, the earphone jack must
be stereo 1/4”at the same time please rotate the volume knob to adjust the proper monitoring volume.
(Please note: In order to protect your ears, the volume must be adjusted properly, it can’t be too loud, and if too
loud the earphone output will be distorted.)

PEM-1000R Receiver
1. Using the battery and the battery automatically management system
The receiver requires two pieces of normal or rechargeable AA-Batteries (25). Insert the batteries into the
Battery Compartment (25). Observe the correct polarity and close the Battery Door (26). The normal AA
battery can run more than 8 hours. When the battery voltage is less than 1.9V the power management system
will power off the unit automatically to protect the batteries from leakage.
(Notes: The normal batteries must be with good quality and without leakage. The rechargeable battery must be
the Ni-H battery without memory effect but large capacity.)
2. Earphone connection
Connect the stereo monitoring earphones jack into the receiver.
Plug in the stereo monitoring earphone jack to the 1/4” stereo Earphone Jack (18), or can also connect any
normal earphone or put the output terminals to be connected with other audio equipments’ audio signal input.
(Please note: The earphone output jack is stereo output, please pay attention to the fact that the connecting
plug must be stereo plug, if it is the mono jack, it will be possible to get short-circuit on the output and then
damage one side of the earphone output.)
(Note: Wipe the earphones and rubber mounts with an antiseptic before and after each use to avoid infection.
Stop using the earphones if they are causing discomfort or infection.)
3. Power on the unit and volume control
Rotate the power and Volume Knob (17) on the top of the receiver clockwise to power on the unit, meanwhile
the LCD Display (21) is showing out the working frequencies and battery status. After the unit is on,
continuously rotate the volume knob in clockwise direction to get the volume louder and turn counter clockwise
to reduce the volume.
(Please note: When the battery is weak or too little remaining, the unit can’t be powered on, it is a must to
change new batteries or to check if the batteries are well installed with right polarity.)
4. Sound mode switch
Stereo-Mono Switch (23) can be used to choose if the current earphone should be stereo output or mono output,
when the stereo is chosen, it must work with the transmitter and the transmitter should be tuned to be stereo too.
(Please note: When the stereo output mode is chosen, the sound performance is good while the S/ N ratio is not
good as when choosing mixed sound in mono mode output).
5. Sound Limit mode switch
The Limit Switch (24) is used to keep the headphone output to a limited level.
6. RF signal LED Indicator
When the RF LED Indicator (20) has been lit up, it means there has gotten transmitter’s signal. If the
interference signals at the same frequency, it will also light up. To eliminate the interference please switch to
the non-interference frequency.
7. Frequency setup for either from the Transmitter-Receiver or Receiver-Transmitter
For Transmitter-Receiver: Open the Battery Compartment (26) of the receiver, get the Infrared Receiving
IR (22) to be seen, and should be pointing to the transmitter Infrared Transmission Window (5), press the
SYNC Button (9) on the transmitter until the receiver has gotten the same frequency as the transmitter. Now
the system has been set up successfully set up. Close the receiver’s battery compartment. If you have more than
one receiver, use this procedure to sync the additional receiver.

Multiple System Operation
Selecting a Channel/ Multiple System Operation
Both the PEM-1000T transmitter and PEM-1000R receiver offer a choice of 100 channels in the UHF band. Select
an open frequency, that doesn’t interfere with any other PEM-1000 or UHF wireless Mic system you are also
using, by pushing the SET Up Button (7) and Manual Up (6) or Manual Down (8) buttons on the front panel of the
PEM-1000T until the channel you want is displayed on the LCD Display (4). You will also need to select the same
channel for the transmitter (see Transmitter Operation instructions above). If different mixes are required for the
different performers, additional PEM-1000T transmitters and receivers set to other channels must also be used,
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 the band(s), up to 8 PEM-1000 systems on different frequencies can
be operated simultaneously to provide multiple discrete mixes to the performers.
[Note: After selecting a frequency on the transmitter, you must also check with the receiver to ensure that the
chosen channel is open (i.e., no other transmissions from other sources, such as UHF TV channels in your area,
operating at the same frequency). Turn off the PEM-1000T transmitter, and monitor the signal from the PEM1000R (see PEM-1000R instructions page). It should be silent. For optimum operation and range, if you receive
any transmissions or static you must choose another channel that is clear.]
[Note: If, after you complete the set-up, you experience interference or unsatisfactory audio performance, change
the channel until the problem goes away. In the extremely rare circumstance that such a problem persists, turn
off all UHF wireless Mic being used or move their receivers physically away from the PEM-1000T transmitter.
In some instances, UHF wireless Mic and the PEM-1000 system can interact if they are too close in frequency.
Contact the NADY SYSTEMS Service Department for further information if necessary (see SERVICE)]
Multiple Monitor Mixes
Any number of PEM-1000R receivers can be used with a single PEM-1000T transmitter set to the same channel.
Although there are individual controls on each receiver allowing different levels of volume, each receiver will
receive the same transmitted monitor mix (see Selecting Stereo or Mono Mode Reception above for exceptions).
If different mixes are required for the different performers, additional PEM-1000T transmitters and receivers
set to other channels must also be used, and each transmitter must be fed a different mix from the console as
desired.
(Note: Never set more than ONE transmitter to the same operating frequency.)
Testing Receiver Range
Wearing your receiver and earphones, walk around the stage area and listen for audio quality. Depending
on room size, obstructions, amount of reflective metal surfaces, and other conditions that may affect RF
transmission, it is normal that the audio may disappear or “drop out” in certain locations. Such zones, otherwise
known as “null spots” are very small and fixed in location if you are within 100 feet of the transmitter and will
become larger as you approach the ultimate range of your system in that location (up to 500 feet, Depending on
site conditions). Generally, it is possible to eliminate such “null spots” by moving your PEM-1000T transmitter
as little as 12-18 inches in any direction. If that is not convenient (e.g., because the PEM-1000T is rackmounted),
you can also use an optional remote antenna. Contact the NADY SYSTEMS Service Department for information
about remote antennas for the PEM-1000T. After you move the transmitter or relocate a remote antenna, range
walk the stage and other areas you will use in your performance to again check for consistent reception. You are
now ready to use the PEM-1000 system for wireless personal in-ear monitoring.
(Note: Due to the strong transmission power of the PEM-1000T, you may experience compromised audio or static
if the PEM-1000R is too close to the antenna of the PEM-1000T transmitter. Always operate the receiver at least
6 ft (2 m) away from the transmitter antenna.)
12
Cautions During Operation
1. When this in-ear wireless monitoring system is used together with a wireless
microphone system, make sure they are not on close frequencies to avoid their possible
interference with each other.
2. If using a coaxial cable to connect the transmitter to a remote antenna, note that the
coaxial cable must be 50 and less than 5 meters long for optimum operating range.
3. Maintain line-of sight-operation at all times, when possible, for best performance and
range.
4. For best performance use only the supplied power adapter for the transmitter.
5. If using earphone other than those supplied, make sure they have a sensitivity of at
least 110dB/mW. Note that the receiver’s battery life diminishes as earphone volume
is increased or earphones have low sensitivity, which requires more power to drive to a
desired volume.
6. Always remove batteries from receiver if not using them for a long time as leaking
batteries can damage the unit.
