E03 TRANSMITTER

The E03 transmitter is a compact transmitter that broadcasts on one of eight channels in the 72-76
MHz band, to any number of Nady E03 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 Nady E03 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 E03 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 E03 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 E03 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 E03 receiver. This procedure is easy to do, and is explained in the receiver instructions,
which follow.

Congratulations on your purchase of the Nady E03 Personal In Ear Monitor™ wireless system. The
E03 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 E03 consists of one wireless transmitter (E03-T) and one or more wireless bodypack receivers
(E03-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 E03 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 E03 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 E03 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 E03.

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.
