5 Best practices for successful operation

 Never attempt to operate two or mo re transmitt ers 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 wi th each other. If a goal i s to create a combo system by add ing an option al
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 t ime.

 Ensure the receiver’s anten nas are properly at tached, exposed (not buri ed within a

rack) and oriented as suggested in the Preparin g 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.

 Al ways have all member sets of a mu lti-channel system within the same frequency

band operating in the same frequ ency 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 i ts 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 extremel y 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

-Voice Installation manual 2021.06 | 03 | F.01U.362.808

RE3 UHF

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
sp aces where the dist ance betw een transmitter and receiver ant ennas is sub stantial or
existing RF conditions limit the range betw een transmitter an d receiver. Simple
performance tests will help identify best settings, and having two output power options
will aid in successful operation.

 A l arge 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 su rface or in a 19” rack using th e 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 in to the recei ver DC i npu t 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 speci al care to ensure t he 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 unt il the desired mating transmitter h as 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 tran smi tter paying close attention to the battery polarity

(+ and -) and matching those polarities to the + and – poles of the batt ery
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 con tain 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 distan ce of two to tw elve inches

between t he 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

th e yellow LED l it 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.

background radio noise, as well as maintaining the desired radio system range (the
fu nctional distance b etween transmitt er and receiver antennas). Squelch i s 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 recei ved
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.

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 coul d even be as pesky as a cell phone near ei ther 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 creati ng sporadi c audib le interference. To resol ve, rescan the receiver and sel ect 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 t hat you r ant ennas 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
approp riately-rated 50Ω B NC-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
th e recei ver’ s RF meter, set the transmitter output power to high, then look for improved
ran ge.

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 lo cate frequencies which are not affected by UHF television or oth er 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
th e USA or Canada, the 6M band will have no co mpeting UHF television signals because
653-663MHz is designated for wirel ess microphones o nly 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
strategical ly created to be intermodulation free using advan ced frequency coordin ation
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, whi ch bot h 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 evalu ate avai labl e sp ectrum and how it align s 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 acti ve antenna splitt ers which wil l cascad e 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 t he two will be influenced b y coverage area an d th e length of antenna cable
between an tenn a and recei ver rack. The PLPA, although passive, has 10dB of passive gain ,
and may be fine if the receiver rack is on stage, however the ALPA acti ve antenna h as
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
cab les t o run the antenn a signals to the first AASP spli tter. Cho ices are RE3-ACC-CXU25
twenty-five foot, RE3-ACC-CXU50 fift y foot , RE3-ACC-CXU75 seventy-five foot, or RE3-ACC­CXU100 one hundred fo ot. 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 ant enna cabl es 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 gai n 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 th e 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
th e 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 o f 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 approxi mate RF g ain whi ch is received
at t he antenna. The RE3 op tional antenna coax cables should perform as per: 25-foot

CXU25 will lose approxi matel y 1.3 dB on the run, the 50-foo t CXU50 will lo se approximately

1.4 dB on the run, the 75-f oot CXU75 will lose approximately 2.4 dB on the run, and the 100­foot 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 deplo y ALPA (set to +10 dB) follo wed by CXU100 (-

4.4 dB), the n et RF gain at th e recei ver is approximatel y +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
fo r it after th e loss (place a booster at the ant enna location, and not th e 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.
