Introduction

Thank you for choosing the Nady EO3 Personal In Ear Monitorwireless system, we know you will be very pleased with its performance and features. The EO3 provides high quality, yet cost-effective in-ear monitoring to on stage performers or behind the scenes personnel. The system is designed to be very easy to use and requires no installation.

The EO3 consists of one wireless transmitter (EO3-T) and one or more wireless bodypack receivers (EO3-R) on the same channel. The transmitter features eight factory switchable channels; the receivers are single channel units that operate on one of eight channels in the 72-76 MHz band, with wide band modulation for quality audio. These frequencies are in a separate band that will not interfere with simultaneous use of VHF or UHF wireless systems on the same stage.

The EO3 system has a wireless operating range of 300 feet, which allows it to be used with confidence in venues from small clubs to large theatres.

The transmitter connects to a monitor or line out from any mixing console, and broadcasts the audio as an FM signal to any number of pocket size Nady EO3 receivers on the same channel. Each receiver is equipped with an adjustable volume control, and high performance earbuds.

Earphone enhancers—unique clear soft plastic inserts that can help secure the earbuds—are included. The transmitter also provides a microphone input to allow wireless cueing of the performers on stage.

The EO3 can provide a high quality monitor mix at significantly lower decibel levels than floor monitors. This is an important benefit for artists who wish to protect their hearing from excessive and potentially damaging sound pressure levels.

Please read this manual completely before using your Nady EO3.

Important Note

Just as with any in-ear monitor system, the EO3 works best when used exclusively by all the 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 earbuds, in the worst cases, thus hindering their effectiveness. Experiment with your mix to get the maximum benefit from your EO3.

EO3 Transmitter

The EO3 transmitter is a compact transmitter that broadcasts on one of eight channels in the 72-76 MHz band, to any number of EO3 wireless bodypack receivers on the same channel. The system provides a 300 ft. wireless operating range, and offers these features:

Eight factory switchable channels

Rear panel input for line level audio

Front panel input for microphone

Audio input gain control

Automatic level control

Extendible antenna

9 volt DC input for AC-EO3 9VDC regulated power supply adapter provided

Power switch with red LED power on indicator

Audio modulation LED indicator

Setting Up the Transmitter

Your EO3 requires minimum installation. Simply place the transmitter on any

flat surface, connect your mixing board to the transmitter’s back panel input (See Connecting Audio Input below), connect the included power supply

(as explained below), and the transmitter is ready to broadcast to any number of EO3 receivers operating on the same channel.

Powering the Transmitter

Connect the AC adapter provided into the 9V DC jack (1) on the back panel of the transmitter. Plug the other end into an AC wall socket. Press Power switch (2). The Power On LED (3) will light.

Antenna

Extend Antenna (4) fully and position 90 degrees from top of the transmitter.

Connecting Audio Input

The Line In jack (5) on the rear panel lets you connect the EO3 to your mixing console. This 1/4” mono phone jack accepts an unbalanced line level audio source at zero dBm nominal signal level. If your mixer has XLR outputs only, you will need an XLR-to-phone plug adapter, available from most electronics stores and music equipment stores.

Using a Microphone

The Mic jack (7) on the front panel allows wireless cueing of on stage performers.

Important: This 1/4” mono phone jack is designed for an electret condenser microphone, and 9V DC power is present at the input jack. If you wish to use a conventional dynamic microphone, at least 20 dB more gain is required, and a preamp should be used. If a preamp is used, be sure to have a blocking capacitor (1 mfd) between the preamp output and the EO3 mic input. If a dynamic mic is plugged into the mic input by mistake, there should be no damage because the current is limited to 1.0 mA. If you have any questions, contact Nady Customer Service (510.652.2411) or your Nady dealer.

Audio Input Gain Adjustment

You can quickly adjust the transmitter to obtain optimum performance with the

Input Gain control (8). The audio modulation indicator LED, marked TX (6) will increase in brightness as the control is turned clockwise, and decrease in brightness as the control is turned counterclockwise. When the “TX” LED is flashing during transmission, the transmitter is broadcasting properly. (If the LED stays off continuously or barely flashes at all, the input gain needs to be increased. If the LED stays on continuously and does not flash during modulation, the input is overloading and needs to be decreased.) You will also need to test the transmitter in use with an EO3 receiver. This procedure is easy to do, and is explained in the receiver instructions, which follow.
