NADY E03 RECEIVER
The E03 receiver is a pocket sized wireless audio receiver with an output for earbuds to provide in
ear monitoring, and offers these features:
• Any number of E03 receivers can be used with a single EO3-T transmitter
• Ultra compact and lightweight
• Preset to one of eight channels in the 72-76 MHz range
• Loudness adjustable with volume control—provides up to 130dB in-ear monitoring
• Antenna is integral with earphone cord
• A pair of mini binaural EB-3 earphones included, with optional-use EMI soft rubber inserts supplied
• LED “power on” indicator
• Accepts standard 9V alkaline battery
CHANNEL SELECTION
Your receiver is pre-tuned at the factory to the same channel as your transmitter. Should you wish to
have your transmitter channel changed, as explained in the Transmitter section of this manual, you must also
have your receiver(s) retuned as well. Contact the Nady Customer Service Department for details.
POWERING THE RECEIVER
Install a 9V battery in battery compartment
1
, observing polarity. To preserve battery life,
always turn the E03 receiver off when it is not in use. When the sound becomes weak or distorted, replace
the battery. The number of hours of operation per battery is as follows: carbon zinc type battery: 10-12 hours
alkaline battery (recommended): 17-20 hours.
USING THE EARBUDS
Simply plug the included earbuds into the earphone jack
2
on top of the receiver. Note: Proper
sound levels on stage are essential for optimum effectiveness of any in-ear monitor system. (See also “Important
Note” on page 1). If sound levels are high, it is important to properly seal out unwanted sound so the ear-
bud can be effective in providing proper monitoring. Top high end in-ear monitor systems use special trans-
ducers imbedded in a soft plastic mold of the users ear canal. This ensures a perfect seal and maximum immu-
nity from bleed through. Such ear mold speakers are very expensive and can be used with the EO3 for opti-
mum results (Call Nady systems for more information.)
The EB-3 mono earbud earphones supplied with the E03-R receiver offer great sound and can also
provide top results if utilized properly. If sound pressure levels are high and bleed through is a problem, care
must be taken to ensure a proper fit and a tight seal. Although the earphones can often be used effectively
simply as “Walkman”- style earbuds, for best results in high SPL environments you must also use the supplied
EMI-S/M/L soft rubber inserts
5
. Choose the correct size (small, medium or large) from the 3 sets
provided for a “custom” fit and slip over the earphones before inserting in your ears. Although the maximum
volume available may be slightly diminished, use of the EMI inserts does provide a better sound seal,
increased immunity from bleed through and mimics the results available with custom-made ear mold speakers.
OPERATING THE RECEIVER
While wearing your earbuds, turn the receiver on by rotating the On/Off Volume wheel
3
. The
power on indicator
4
will go on. (To turn the receiver off, rotate the On/Off/Volume wheel until it clicks,
and the “power on” indicator will go out.)

CONFIRMING CORRECT INSTALLATION
The transmitter’s “TX” LED
6
will flash when a microphone or line level signal is broadcast by the
transmitter. If “TX” does not flash, turn the audio input gain control clockwise. This will increase audio level
and cause “TX” to flash along with the program source. When “TX” is flashing, the transmitter is broadcast-
ing properly. Test the transmitter with an EO3 receiver. This procedure is explained in the receiver instruc-
tions.
*For the best performance, (and to minimize the possibility of interference from another source), we suggest
you experiment to find the minimal height the antenna must be extended in order to perform well in your
particular environment.
CHANNEL SELECTION
Channel selection is controlled by DIP switches inside the transmitter. The system is preset at the fac-
tory. Changing the channel can be done quickly by any qualified service technician. Contact your dealer
or the Nady Customer Service Department for details.
USING MORE THAN ONE E03 SYSTEM
You may operate up to three E03 systems in the same location. For example, you may want to use
one transmitter to provide a mix to the rhythm section, a second to provide a different mix for the vocalist.
For multiple system operation, please observe:
• If operating two E03 transmitters in the same location, use Ch. AA and HH (or GG).
• If operating three E03 transmitters in the same location, use Ch. AA, EE and HH (or GG).
• Locate the transmitters ten feet or more away from the performers wearing E03 receivers.
