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 EO3 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 earbud can
be effective in providing proper monitoring.
Top high end in-ear monitor systems use special
transducers imbedded in a soft plastic mold of the
users ear canal. This ensures a perfect seal and
maximum immunity from bleed through. Such ear
mold speakers are very expensive and can be
used with the EO3 for optimum results—call
Nady Systems for more information.
The EB-3 mono earbud earphones supplied
with the EO3-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 three 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.)
