E03 manbook 10/16/01 2:24 PM Page 1 WIRELESS SYSTEM Model O W N E R ' S1 M A N U A L E03 manbook 10/16/01 2:24 PM Page 2 Congratulations on your purchase of the Nady E03 Personal In Ear MonitorTM 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. 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. I M P O R TA N T N O T E 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. 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. 2 3 E03 manbook 10/16/01 2:24 PM Page 4 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 broadcasting properly. Test the transmitter with an EO3 receiver. This procedure is explained in the receiver instructions. *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. 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 Channel selection is controlled by DIP switches inside the transmitter. The system is preset at the factory. Changing the channel can be done quickly by any qualified service technician. Contact your dealer or the Nady Customer Service Department for details. 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. 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. E03 Transmitter Front Panel 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 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 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. 7 Mic Input 6 Audio Modulation LED 2 Power Switch 3 "Power On" LED E03 Transmitter Back Panel 4 Antenna 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.) 5 Line In Jack 8 Input Gain Adjust Channel Switches (Inside) 1 9V DC Jack 4 5 E03 manbook 10/16/01 2:24 PM Page 6 ADJUSTING EAR MONITOR VOLUME Listen for your program source, and adjust receiver volume to a comfortable listening level. The E03 receiver is capable of providing listening levels loud enough to be heard in use with a rock band. Many bands use on stage loudness levels that with repeated exposure could pose a threat to their hearing. Therefore, it is very important that the E03 be used at a reasonable and comfortable listening level. NOTE: A slight hum may be heard if the receiver is used within six feet of the transmitter. This is normal and does not affect performance.
