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.)
