5 Best practices for successful operation

Never attempt to operate two or more transmitters on the same frequency at the same time. While multiple receivers can successfully tune to a single transmitted frequency, multiple transmitters simultaneously operating on the same frequency will immediately interfere with each other. If a goal is to create a combo system by adding an optional transmitter (one bodypack transmitter and one handheld transmitter to work with one receiver), only one of those transmitters can be on and tuned to the receiver at a time.
Ensure the receiver's antennas are properly attached, exposed (not buried within a rack) and oriented as suggested in the Preparing the receiver section, page 17.
Scan for open frequencies first with transmitter off. The receiver antennas must be properly connected for best scan results.
When scanning and synchronizing a multi-channel system, scan and synchronize one system at a time. To begin, have all transmitters off and scan system receiver 1 first. Then turn on system transmitter 1 and sync it to receiver 1. Leaving system transmitter 1 on, move on to receiver 2. With system transmitter 1 on, scan system receiver 2 and tune it to the next open frequency within the same group as system 1. Turn on system transmitter 2 and sync it to system receiver 2. Then leave system transmitter 2 on. Follow this process while scanning and syncing all channels within a multi-channel system.
Always have all member sets of a multi-channel system within the same frequency band operating in the same frequency group. Mixing frequencies (channels) from different groups within the same frequency band is not recommended. Channels within a group are intermodulation-free. Simultaneous operation of channels from different groups may lead to intermodulation interference.
If desired, use the receiver's mic configuration menu items to set transmitter operating parameters prior to syncing the transmitter to the receiver. If a receiver's mic configuration is changed since the last transmitter sync, resync the transmitter to update its parameter settings.
Properly setting transmitter sensitivity is key to optimum performance. Best practice: While observing the receiver's AF meter activity, adjust the transmitter sensitivity so that high vocal peaks light the yellow LED segment. Under extremely loud vocal peaks, an occasional red LED segment light is OK, but a solid and constant red LED should be avoided.
Choosing transmitter low or high power: The transmitter in your set may have two output power setting options (8M band has only one). The higher setting may not be appropriate for your application as it is possible that high may be too high based on the

distance between the transmitter and receiver antennas, or other systems within close proximity in a multi-channel system. Low is likely to be sufficient when the set is in a small to medium size room or space. High may be the best choice for large rooms or spaces where the distance between transmitter and receiver antennas is substantial or existing RF conditions limit the range between transmitter and receiver. Simple performance tests will help identify best settings, and having two output power options will aid in successful operation.

- A large multi-channel system can be made up of sets operating in different frequency bands. This is a good method to follow when maximizing a high channel count system potential. Based on RF conditions in the operating vicinity, select appropriate numbers of sets from available bands in your country to achieve a desired high channel count system.

6 Quick setup

6.1 Preparing the receiver

a. Remove the receiver, packaged power supply kit and two antennas from the product carton.
b. Place the receiver either on a stable flat surface or in a 19" rack using the rack kit supplied.
c. Locate the power supply and attach the supplied AC wall outlet clip which is appropriate for your country's mains power by sliding it into the power supply head, and plug the DC power lead end of the cable into the receiver DC input jack.
d. Locate, unwrap, and attach the two supplied receiver antennas by inserting them onto the receiver's BNC antenna jacks and locking them into place by applying a right-hand twist. Take special care to ensure the receiver antennas are exposed to open air, not touching any items that would ground them, and oriented 90 degrees to one another and positioned at 45 degrees relative to the floor.
e. Turn on the receiver by pressing the power button.
f. Ensure the transmitter for this set is turned off.
g. Press the scan button and follow the scanning instructions described in Scanning for open channels, page 24.
h. After the scan is complete, select the group and channel from the results list which best matches your system needs.
i. Follow the scanning instructions in Scanning for open channels, page 24 to return the receiver's display to the home screen.
j. Leave the receiver on until the desired mating transmitter has been prepared and synced.

6.2 Preparing the transmitter

a. Remove the transmitter, batteries, and input device (if supplied) from the product carton.
b. Insert the batteries into the transmitter paying close attention to the battery polarity (+ and -) and matching those polarities to the + and - poles of the battery compartment battery clips.
c. Connect the transmitter's input device to the transmitter (a bodypack set will contain either a lavalier microphone, headworn microphone, or instrument cable – a handheld set will contain a thread-on microphone head.
d. Turn on the transmitter by pressing the power button.

6.3 Sync the transmitter to the receiver

a. Locate the transmitter's sync port and the receiver's sync emitter which are both identified with the (●) symbol.
b. Maintaining direct line of sight and a separation distance of two to twelve inches between the transmitter and receiver ports.

c. Directly aim the transmitter sync port at the receiver sync emitter.
d. Press the sync button on the front of the receiver to begin the syncing process (green LED flashes on receiver).
e. Hold the transmitter in place until the sync process is complete. Upon successful sync the transmitter will be tuned to the receiver and ready for use.

6.4 Ensure transmitter input sensitivity is set for best signal level

a. While viewing receiver AF meter activity, perform as you would in a normal performance using proper microphone placement.
b. Observe the AF meter LED segments. Ideal level should show all green LEDs and the yellow LED lit on emphasis peaks. An occasional red LED is OK, but a constant, solid red LED should be avoided.
c. Adjust transmitter input sensitivity until item b above is achieved.

Upon successful completion of this section, your set is ready for operation.

Setting the squelch appropriately based on conditions is important to controlling background radio noise, as well as maintaining the desired radio system range (the functional distance between transmitter and receiver antennas). Squelch is basically a noise gate across the receiver's audio path that is keyed open by a combination of audio path signal level, and the presence of a unique combination of tone codes in the received signal. Squelch sets the threshold where the received signal amplitude will open the noise gate. Signals above the threshold will open the audio path gate, while signal levels below the threshold will not open the gate.

NOTE: Improperly set squelch negatively affects system range (the distance between transmitter and receiver).

Press the ▼ button to scroll down to Squelch on the main menu. Select by pressing SET to enter the Setup Squelch screen.

ELECTRO-VOICE RE3-RX5L - Adjusting receiver squelch - 1

The display shows the current squelch setting. The numbers on this scale are arbitrary values from -5 to the left of 0, to +10 to the right of 0. Higher number values tighten the gate threshold, while lower number values loosen the gate threshold.

While gripping the transmitter handle/battery cover section (item 2 shown above) with one hand, grip the control section (item 3 shown above) with the other hand. Using a left-hand twist, unscrew the control section until it is free from the handle. Slide the control section away from the handle until the battery compartment (item 6 shown above) is fully exposed.
Gently rotate the hinged protective battery cover to expose the battery chamber. Note the battery polarity markings (+ and -) on the protective cover. Both positive (+) contacts are adjacent to the control section male threads.
Install two fresh, high quality AA alkaline batteries (or fully charged AA size NiMH rechargeable cells) paying close attention to match the polarity markings (+ and -) on each battery to the polarity markings (+ and -) of the battery contacts as shown on the battery cover.
Once both new batteries are properly installed, rotate the hinged protective battery cover downward until the cover is in contact with the batteries.
Applying the same gripping technique used while opening the transmitter to expose the batteries, gently slide the battery compartment back inside the handle until the control section can move no further. Using a right hand twist, screw the control section onto the handle section until it is tightly threaded on. Be careful not to overtighten the threads.

Editing any of the following parameters locally on the transmitter is possible. These edits will override the settings synchronized from the mated receiver. Additionally, any parameter value changes made locally on the transmitter may be overwritten the next time

	DC power distribution cable from AASP splitter not properly connected (if used).	Ensure DC distribution cable is fully plugged into receiver DC input jack and the other end is fully plugged into an AASP DC output jack.
	AC mains circuit is off.	Ensure AC circuit is live by testing another AC powered item. If necessary, locate and reset circuit breaker.
	Power button may be damaged.	The RE3 receiver power button is robust and durable, and is unlikely to fail. If other listed resolutions do not solve the problem contact your local Electro-Voice service center.
Transmitter will not turn on.	Dead batteries.	Replace with fresh, high-quality alkaline batteries.
	Battery polarity reversed.	Ensure battery + and - ends are in contact with the like-marked battery compartment contacts.
	Power button may be damaged.	RE3 transmitter power buttons are robust and durable, and are unlikely to fail. If properly-inserted and known-to-be-fresh batteries will still not turn on transmitter, contact your local Electro-Voice service center.
Symptom	Possible cause	Possible resolution
Short transmission range.	Transmit power too low.	Set transmitter power to high setting.
	Receiver squelch set too high.	Adjust receiver squelch by trying lower number values until desired range is achieved.
	Improperly placed receiver antennas.	Place receiver antennas out in the open in the shared space of the transmitter away from reflective or grounding surfaces.
	Disconnected, incorrect, or failed antenna cable.	Ensure a known-to-be functional and appropriate 50Ω BNC-terminated cable is fully connected at the antenna and receiver.
	Competing RF signal at the receiver.	Turn off the transmitter and observe the receiver RF meter. If any RF is showing, follow the scan process and select a new clear frequency. Then turn on the transmitter and resync it to the receiver's new data.
Low AF signal on receiver meter.	Transmitter sensitivity set too low.	Adjust transmitter sensitivity so that high vocal peaks light the yellow LED segment. Under extremely loud vocal peaks, an occasional red LED segment light is OK, but a solid and constant red LED should be avoided.
Unstable radio reception.	Radio interference.	Turn off the RE3 transmitter and observe the receiver RF meter. If any RF is showing, follow the scan process and select a clear frequency. Then turn on the transmitter and resync it to the receiver's new data.

11.2 Frequently Asked Questions

Q - Why was my system working fine at sound check, then suddenly it started getting interference during the performance?

A – Using RF wireless can be quite tricky. Sources of competitive RF are everywhere, and they can appear unpredictably. A competing RF signal that wasn’t present during your sound check probably went active during the show. This could be another member of the wireless microphone community in the venue that was off during sound check – possibly another performer’s wireless rig was turned on during your show, and now is interfering with your system. The source could also be a computer (CPU) positioned near the receiver or antennas that wasn’t on earlier. It could even be as pesky as a cell phone near either the transmitter or receiver, which while not being used for a call, is sending GPS signals

periodically, emitting a signal (if close enough to the transmitter or receiver) which could be creating sporadic audible interference. To resolve, rescan the receiver and select a new clear frequency. Then resync the transmitter to the new receiver data.

Q - It seems that when the performer walks way out into the audience, the system starts losing signal. Why am I not getting the range from the system I need?

A – This could indicate a variety of influencing factors. The first thing to check is if your system is, or is not, sharing a frequency with another signal at the receiver. While observing the receiver's RF meter, turn off the transmitter. If the RF meter continues to show signal after the transmitter is off, your transmitter is competing with another signal at the receiver. To solve, perform the scan process, tune the receiver to a new clear frequency, then turn on and sync the transmitter to the new receiver data. The second thing to check is receiver antenna placement and cables. Ensure that your antennas are out in the open in the shared space of the transmitter (meaning not behind walls or in another room), away from reflective or grounding surfaces, and connected to the receiver with appropriately-rated 50Ω BNC-terminated coax cable. The third thing to check is the receiver squelch. Many times, having the squelch set too high will greatly reduce system range. Try lowering the squelch (number value) to increase system range. The fourth thing to check is transmitter output power. If a compromised range is accompanied with low RF signal on the receiver's RF meter, set the transmitter output power to high, then look for improved range.

Q - Why is it hard to find an open frequency in my location?

A – RE3 shares the UHF radio spectrum primarily with UHF television broadcasters. Geographically, some broadcast areas are more densely packed with television broadcast signals than others. A full system scan looks through the entire tuning bandwidth of the receiver and will locate frequencies which are not affected by UHF television or other RF signals. Knowing your local RF environment is important. Those local television stations which broadcast their strong and wide signals into the air are regulated by the government, and consulting government databases will help identify the frequency areas occupied by local broadcasters. RE3 tuning bandwidths are relatively wide, allowing generous tuning options, however if the airwaves aligning with your particular RE3 tuning bandwidth are filled up with UHF television, finding open frequencies will be difficult. Selecting the best band for your area is important. Something to consider is if you are using your RE3 set in the USA or Canada, the 6M band will have no competing UHF television signals because 653-663MHz is designated for wireless microphones only as a result of the reallocation of 600MHz initiatives.

Q - I manually created frequencies for my multi-channel system. Why am I getting interference between the channels?

A – Manually creating custom tuning schemes without the assistance of frequency coordination software may contribute to the problem described. RE3 frequency groups are strategically created to be intermodulation free using advanced frequency coordination software. It’s likely that your self-made grouping has created destructive intermodulation

artifacts which would be avoided by staying with our factory groups. Use RE3 factory groupings. They work well.

Q - Why doesn't the extra RE3 transmitter I bought online work with my RE3 set?

A – The set you originally purchased was pre-configured with a matching transmitter and receiver, which both operate in the same frequency band (5L, 5H, 6M, etc.). If you add another transmitter, it has to be of the same frequency band to work. As this particular question is about additional transmitters, it should be pointed out that adding a second transmitter to an existing set with plans to use both transmitters at the same time with the one existing receiver will not work. At any given time, one of the two transmitters tuned to the receiver's frequency must be off. If they are both on and the same time, substantial interference will occur.

Q - Will the lavalier microphone I have with my older RE-2 system work with RE3?

A – Yes. Legacy Electro-Voice bodypack transmitter input devices with 4-pin mini connectors are compatible with RE3.

Q – I want to put together an eight-channel RE3 system with two remote antennas on the stage feeding the receiver rack. What do I need?

A – First, choose the frequency band or bands your system will be operating in. Based on your location, you'll need to evaluate available spectrum and how it aligns with the RE3 band options. Knowing that information, one option would be to select the same band for all eight sets. Another option is to split the eight by selecting four sets from one band, and the other four from another band, thereby allowing room to compensate for unforeseen changes. You'll probably be rack mounting your receivers, so you'll need four RMK2 dual rack mount kits, which will mount the eight receivers in four rack spaces. You'll need two AASP active antenna splitters which will cascade the RF from two antennas into the eight receivers. You'll need either two PLPA passive log periodic antennas, or two ALPA active log periodic antennas on stage. They will mount on standard microphone stands. Choosing between the two will be influenced by coverage area and the length of antenna cable between antenna and receiver rack. The PLPA, although passive, has 10dB of passive gain, and may be fine if the receiver rack is on stage, however the ALPA active antenna has adjustable gain (selectable 3dB and 10dB amplified), and if the cable run to the receiver rack is lengthy, it may be the best choice. You decide. You'll need TWO low-loss coax cables to run the antenna signals to the first AASP splitter. Choices are RE3-ACC-CXU25 twenty-five foot, RE3-ACC-CXU50 fifty foot, RE3-ACC-CXU75 seventy-five foot, or RE3-ACC-CXU100 one hundred foot. The splitter has all cables required if you connect your remote antenna cables to the rear of the first AASP, but if you want to attach the antenna cables at the front of the rack, you'll need to add an RE3-ACC-CXUF rear to front mount antenna cable kit. That should do it.

Q - Why am I not seeing much audio level on my receiver AF meter?

A – The transmitter input sensitivity likely needs to be adjusted. It has 30dB of adjustment (-15dB at lowest gain to +15dB at highest gain). On the transmitter, press and hold SET until the characters on the display begin to flash. Continue to progressively press SET until reaching the sensitivity parameter. Press the up button to increase the displayed value. Pressing SET will store the new setting. Continue working with this setting until the receiver's AF meter yellow LED is lighting upon high voice peaks. An occasional red LED will be OK.

Q - My receiver is in lock mode. How do I unlock it?

A – Press and hold the SET button for two seconds then use down button to select OFF. Then press SET. Receiver is unlocked.

Q – Why does my receiver RF meter show RF signal present before I turn on the mated transmitter?

A – There is a competing RF signal now present on that frequency. With the RE3 transmitter off, follow the scan process and select a new clear frequency. Then turn on the transmitter and resync it to the receiver's new data.

Q – The frequency I've had my set tuned to has always worked flawlessly. Why is it that when I traveled to an out-of-town gig, I'm getting interference there?

A – RF environments change city-to-city. When traveling, it's important to remember that UHF television broadcasts are not always on the same channel in every city. Something in the city or venue you traveled to is different. Follow the scan process and select a new clear frequency. Then turn on the transmitter and resync it to the receiver's new data.

Q – Our RE3 systems have been working fine in the small venue we play. We decided to try high power on the lead vocal mic transmitter, and now we're having all kinds of problems. What could be wrong?

A – In your small venue, high output power on any or all of your mics may be too much because of transmitter-to-transmitter, and transmitter-to-receiver proximity. Too much RF gain can actually be more destructive than low RF gain. High RF gain is most useful for long transmission distances, but at short distances, it may contribute to intermodulation with nearby transmitters and receivers. If the low power setting was working for you, switch back to it.

Q - I have a long distance between where I want my antennas mounted and where the receivers will be located. Do I need antenna boosters and high-end coax?

A – This might be a very good idea. The purpose of using antenna boosters and/or active antennas is to compensate for the signal loss incurred by the antenna-to-receiver coax cable run. The system you describe will be improved with active RF antenna components and low-loss coax. Coax cable performance is measured by loss factors, i.e., dB of loss per 100 meters. The goal is to deliver to the receiver the approximate RF gain which is received at the antenna. The RE3 optional antenna coax cables should perform as per: 25-foot

CXU25 will lose approximately 1.3 dB on the run, the 50-foot CXU50 will lose approximately 1.4 dB on the run, the 75-foot CXU75 will lose approximately 2.4 dB on the run, and the 100-foot CXU100 will lose approximately 4.4 dB on the run. Factoring in the gains of the antennas, the passive log periodic PLPA is +10 dB, the active log periodic ALPA is either +3 dB or +10 dB (selectable), and the active booster RFAMP is +10 dB. So for example, if your antenna cable run is 100 feet, and you deploy ALPA (set to +10 dB) followed by CXU100 (-4.4 dB), the net RF gain at the receiver is approximately +5.6 dB, which is fine. A handy way to think of it is booster/antenna gain minus cable loss equals net received RF gain. We should also emphasize that an RF boosting device should precede the loss, not make up for it after the loss (place a booster at the antenna location, and not the receiver location).

Q - I'm using an RE3 bodypack wireless for my bass guitar with active pickups and I'm blasting the receiver hard. What could be wrong?

A – Your bodypack transmitter input pad should be engaged. Locate the -20 dB attenuator setting in the menu and set it to ON. If further transmitter audio signal gain reduction is necessary, locate the sensitivity setting in the menu and bring the sensitivity down a few dB as well.

Term	Definition
System vs set	Because the terms system and set can be used interchangeably, thereby causing confusion, this manual refers to a set as a single mated pair of one transmitter and one receiver. Whereas a system is the collection of multiple wireless sets and antenna distribution items.
Set	A pre-packaged combination of receiver, receiver antenna, receiver power supply, transmitter, transmitter input device, and other supplied accessories. For example, if you purchased an RE3-ND76-5L, the manufacturer considers it a set. Also it is the basic hardware combination of a mated transmitter and receiver.
SET	A multi-purpose menu navigation key which functions as an enter key, a menu advance key, an item select key, and a save or store key.
Scroll	To navigate up and down menus or item options using the ▲ and ▼ buttons.
Group	A predefined combination of intermodulation-free frequencies.
Channel	As it relates to frequencies within a group, it is the exact frequency a set can be tuned to.As it relates to a multi-channel system, it is the quantity of unique paired transmitters and receivers. For example, a multi-channel system consisting of eight receivers and eight mated transmitters is said to be an eight channel system.
Intermodulation	The adverse reception interference that occurs when two or more non-coordinated frequencies produce harmonics which disrupt reception of one or more channels.
SYNC	The operation of synchronizing a receiver's transmitter data to the mated transmitter.
RX	Abbreviation for receiver.
TX	Abbreviation for transmitter.
RF	Abbreviation for radio frequency. RE3 is an RF wireless microphone set operating in the UHF radio spectrum.
UHF	Abbreviation for ultra-high frequency, and is the term when applied to wireless microphone products as the portion of radio spectrum shared with UHF television signals between 470MHz and 865MHz. Those limits vary by country where used.
MHz	Abbreviation for megahertz denoting frequencies measuring in the millions of cycles per second. A common reference for wireless microphones using this shortened numerical expression could be
	652.725MHz (six-hundred fifty-two million, seven hundred twenty-five thousand cycles per second).
Multi-channel system	A system made up of two or more sets where each set is tuned to a specific frequency (channel) which does not interfere with the operation of other member sets within the system. A multi-channel system can be made up of sets all from the same frequency band, or sets from multiple frequency bands.When using multiple sets operating in the same frequency band, each set must be operating on a frequency-coordinated channel within the same group.
