(US Patent Pending)
The Lectrosonics Digital Hybrid Wireless™ uses innovative technology to combine the new advantages of digital
audio with the classic advantages of analog RF transmission, thus delivering the superior sound quality of a
digital system and the excellent range of an analog
system. A proprietary algorithm encodes the digital
audio information into an analog format which can be
transmitted in a robust manner over an analog FM
wireless link. The receiver employs the latest filters, RF
amplifiers, mixers and detector to capture the encoded
signal and a DSP recovers the original digital audio.

™
This digital/analog hybrid technique has some very
beneficial properties. Because the information being
transmitted is digitally encoded, immunity to noise is
much higher than a compandor can offer. Because the
encoded audio is sent in analog format, spectral and
power efficiency and operating range are not compromised. Under weak RF conditions, the received signal
degrades gracefully, like an analog system, delivering as
much usable audio as possible at maximum range.
Because the audio is not companded, no compandor
artifacts are present at any audio or RF signal level. This
greatly reduces the pumping and breathing problems
commonly found in wireless systems with compandors.

UHF Wireless Digital HybridTM Receiver
GENERAL TECHNICAL DESCRIPTION
The UCR511 is a portable, high performance, tripleconversion, frequency synthesized, UHF receiver fully
compatible with all Lectrosonics 500 series transmitters
(and some other transmitter types – see Compatibility
Modes for details.) The RF performance is extremely
stable over a very wide temperature range, making the
UCR511 perfectly suited to the rough environmental
conditions found in the field. The proprietary audio
processing includes a digital signal processor for very
low distortion and a superior signal to noise ratio.
The UCR511 features a menu-driven LCD graphic
display and three control buttons to conveniently view
and alter user settings. The main window, for example,
displays the pilot tone indicator, antenna diversity phase,
RF level, audio level, receiver battery status and transmitter battery status. It is also possible to bypass the
pilot tone/squelch from the main display window. Other
display windows show operating frequency, audio output
level, battery voltage and test tone status. The frequency scan mode provides a spectrum analyzer for a
graphical means of observing all signals “on the air”
within the frequency range of the receiver in order to find
operating frequencies that are free of interference.
COMPATIBILITY MODES
The UCR511 receiver was designed to operate with
Lectrosonics 500 Series transmitters and will yield the
best performance when doing so. However, due to the
flexibility of digital signal processing, the UCR511 is also
able to operate with Lectrosonics 300 Series, Lectrosonics 100 Series, and certain non-Lectrosonics transmitters
in special compatibility modes.
DIVERSITY RECEPTION
The UCR511 technology with SMART Diversity™ minimizes dropouts in situations where multi-path reflections
can cause serious problems. The phase diversity
network and PIN diode RF switches are controlled by the
microprocessor using a sophisticated algorithm to use
both antennas simultaneously. This design keeps the
receiver compact enough for camera mounting or
shoulder bag applications, yet provides effective diversity
reception.
RF FREQUENCY TRACKING FRONT-END AND MIXER
The receiver is frequency agile and can be set to operate
on any one of 256 frequencies within its tuning range. To
significantly reduce unwanted interference and intermodulation problems, the UCR511 has a frequency
selective front-end section that tracks and tunes to the
desired signal frequency and rejects or “tunes out”
unwanted interfering signals. The design consists of four
varactor tuned ceramic transmission line resonators
controlled by the microprocessor to provide excellent
selectivity. The low noise high current RF amplifier was
designed with feedback regulation for stability and
precise gain in order to handle stronger RF signals
without output overload. The first mixer is of new GaAs
technology that has a very high third order intercept
point. This produces a robust front-end that is as selective as fixed single frequency designs and is suitable for
use in close proximity to other receivers and transmitters
commonly used in field production “bag” systems.
MICROCONTROLLER, PLL AND VCO CIRCUITS
The 8-bit microprocessor is truly the “heart” of the
UCR511 receiver. It monitors user command inputs from
the front panel control buttons and numerous other
internal signals such as RF level, audio levels, pilot tone
levels and external/internal power voltages. Outputs
from the microcontroller drive the LCD display and
backlight, control the squelch and audio output attenuator, and operate the front-end tuning, the PLL/VCO
circuits and the antenna phase switch. The UCR511
design and the advanced technology of the microprocessor control arguably set a new standard in wireless
microphone development.

(Surface Acoustical Wave) filters. The 244 MHz SAW
filters combine sharp tuning, constant group delay, wide
bandwidth and excellent temperature stability, far superior to conventional LC filters. The 244 MHz first IF
signal is converted down to 10.7 MHz, filtered through
two ceramic filters for sharp selectivity, then converted to
300 kHz.
DIGITAL PULSE COUNTING DETECTOR
The UCR511 receiver uses an elegantly simple, yet
highly effective digital pulse detector to demodulate the
FM signal, rather than a conventional quadrature detector. This unusual design eliminates thermal drift, improves AM rejection, and provides very low audio
distortion.
DSP-BASED PILOT TONE
The above description applies only in 500 Series mode. In 300
Series mode, only one pilot tone frequency is used on all channels,
emulating the original crystal-based system. In other compatibility
modes, no pilot tone is used.
The 500 Series system design uses a DSP generated
ultrasonic pilot tone to control the receiver audio muting
(squelch). Brief delays (preset into the UCR511 circuitry) eliminate thumps, pops or other transients that
can occur when thewhen the associated 500 Series
transmitter is turned on or off. The pilot tone frequency
is different for each of the 256 frequencies in the tuning
range of a system (frequency block.) This eliminates
squelch problems in multichannel systems where a pilot
tone signal can appear in the wrong receiver via intermodulation products. The DSP generated pilot tone also
eliminates the need for fragile crystals, allowing the
receiver to survive shocks and mishandling much better
than older analog-based pilot tone systems.
SMART SQUELCH
The UCR511 employs a sophisticated squelching system
in an attempt to deliver the cleanest possible audio
during marginal conditions of reception. Any squelching
system faces inevitable trade-offs: squelch too much and
valuable audio information may be lost, squelch too little
and excessive noise may be heard; respond too rapidly
and the audio sounds “choppy,” respond too sluggishly
and syllables or entire words can be cut off.
The UCR511 combines several techniques to achieve an
optimal balance, removing distracting noise, without the
squelching action itself becoming a distraction. One of
these techniques involves waiting for a word or syllable
to complete before squelching. Another incorporates
recent squelching history and recent signal strength,
adjusting squelching behavior dynamically for the most
serviceable result under variable conditions. Using these
Note
™
and other techniques, the UCR511 can deliver acceptable audio quality from otherwise unusable signals.
In the Pilot Tone Bypass mode, the squelch system is
disabled. Received audio remains unmuted at all times
with this setting. (See Front Panel Controls and Functions.)
SMART NOISE REDUCTION (SmartNR™)
The SmartNR setting is user selectable only in 500 Series mode. In
other modes, noise reduction is applied in such a way as to emulate
the original analog system as accurately as possible and is not user
The UCR511 has been meticulously designed using the
best available low noise components and techniques.
Nonetheless, the wide dynamic range of digital hybrid
technology, combined with flat response to 20 kHz,
makes it possible to hear the -120 dBV noise floor in the
mic preamp, or the (usually) greater noise from the
microphone itself. (To put this in perspective, the noise
generated by the recommended 4 k Ohm bias resistor of
many electret lavaliere mics is –119 dBV and the noise
level of the microphone’s electronics is much higher.) In
order to reduce this noise and thus increase the effective
dynamic range of the system, the UCR511 is equipped
with a Smart Noise Reduction algorithm, which removes
hiss without sacrificing high frequency response.
The Smart Noise Reduction algorithm works by attenuating only those portions of the audio signal that fit a
statistical profile for randomness or “electronic hiss”.
Because it isn’t simply the same sophisticated variable
low pass filter as in Lectrosonics’s 300 Series designs,
much greater transparency is thus obtained. Desired
high frequency signals having some coherence such as
speech sibilance and tones are not affected.
The Smart Noise Reduction algorithm has three modes,
selectable from a user setup screen - OFF/NORMAL/
FULL.
OFF, no noise reduction is performed and
complete transparency is preserved. All signals
presented to the transmitter’s analog front end,
including any faint microphone hiss, will be
faithfully reproduced at the receiver.
NORMAL, the factory default setting, enough
noise reduction is applied to remove most of the
hiss from the mic preamp and some of the hiss
from lavaliere microphones. The noise reduction
benefit is dramatic in this position, yet the degree
of transparency maintained is exceptional.
FULL, enough noise reduction is applied to
remove most of the hiss from nearly any signal
source of reasonable quality, assuming levels are
set properly at the transmitter. This additional
noise reduction comes at the cost of some
transparency for low-level room noise, yet the
Note

algorithm remains undetectable under most
circumstances.
RF-CONTROLLED DIGITAL NOISE FILTER
In addition to SmartNRTM, the UCR511 contains an RF
sensitive variable frequency filter, which reduces high
frequency response under extremely weak RF conditions. This filter does nothing until the RF signal strength
drops below 3 uV at which point it begins to roll off high
frequencies. Usable audio remains unaffected, but
noise-ups or “hits” occurring near the fringe of reception
sound much less harsh.
OUTPUT LEVEL ADJUST
One of several setup screens is provided for adjusting
the audio output level in 1 dB steps from -50 to +5 dBu
using the SEL Up and Down buttons on the front panel.
TEST TONE
To assist in matching the audio levels of equipment
connected to the UCR511, a 1 kHz audio test tone,
adjustable from -50 to +5 dBu in 1 dB increments, is
available at the XLR connector. This tone is available
through the TONE display window.
BATTERIES
The UCR511 operates on two 9 V alkaline or lithium
batteries. Access to the battery compartment is gained
by lifting one end and turning the rear panel door.
Do not use an alkaline and a lithium in the same unit. Standard or
“heavy duty” batteries are not recommended.
Note
POWER SUPPLY
The UCR511 may be operated from an external (Negative Ground) DC power source (see Specifications and
Features section for allowed voltages.) The receiver has
a built-in Poly-Fuse to protect the unit. This fuse resets if
the power supply is disconnected for about 15 seconds.
The power section also has protection circuits that
prevent damage to the receiver if a positive ground
power source is applied.
LCD DISPLAY
The display has four primary windows: Main, Setup,
Battery Level, Frequency. Pressing the MENU button
rotates through each of these windows.
If the battery gets low on either transmitter or receiver, a
message will interrupt the display every few seconds and
flash a low battery warning.
After power is turned off and back on again, the unit
defaults to the Main Window and to the most recent
frequency, audio level, transmitter battery type and other
user settings. These settings are retained even if the
batteries are removed. After five minutes of no key
activity, the LCD backlight goes off and the display
reverts back to the Main Window.
POWER UP SEQUENCE
The power up sequence consists of four messages that
appear automatically over a period of a few seconds
after the power is switched on.
1) UCR511
BLK xx (xx is the frequency block number)
2) VERSION
3) COMPAT mode (mode is one of the following:
500 - native 500 Series mode
100 - Lectrosonics 100 Series compatibility
300 - Lectrosonics 300 Series compatibility
MODE 3 - compatible with certain non-
IFB - compatible with all Lectrosonics IFB
4) TUNING mode (mode is one of the following:
NORMAL - tune in single channel increments
GRP x - tune in precoordinated intermod-free
frequencies (x is A, B, C or D))
The Main Window will appears after these introductory
messages are displayed.
The UCR511 is fully operational during the power up
sequence and will immediately respond to button pushes
made before the automatic sequence is completed. If a
valid transmitter signal is already present when the
receiver is turned on, the audio output will typically be
engaged somewhere in the middle of the power-up
sequence, following a brief delay to allow the audio
circuits to stabilize.

voltage with battery icon in main window.
AA TIM - Transmitter uses an AA battery. Display its
voltage normally in the battery level window but monitor
its status with the battery timer in the main window.
The 9V TIM and AA TIM settings are most useful for
NiMH batteries as they do not exhibit reliably identifiable
voltage drops as they discharge.
In compatibility modes other than 500 Series and 300
Series, no battery telemetry information is available so
the TXBAT setup screen offers only two choices:
NOTIMER - Display no transmitter battery status in the
main window.
TIMER - Monitor the transmitter battery status with the
battery timer in the main window. To reset the timer, hold
MENU and DOWN for one second.

SmtNR
The SmtNR setup screen (available
in 500 Series compatibility mode
only) places the Smart Noise Reduction algorithm in one of three modes.
In the OFF position, no noise reduction is applied, for complete transparency. In the NORMAL position
(factory default setting), a moderate
amount of noise reduction is applied,
dramatically reducing hiss with
virtually no discernible side effects.
In the FULL position, the transparency is superior to the Lectrosonics
noise reduction system used for
many years in the 300 series systems. Try switching between the
three modes to decide what setting is correct for your
application. Refer to the Smart Noise Reduction section
in the GENERAL TECHNICAL DESCRIPTION chapter
for more detailed information about this feature.

TUNING
The Tuning Setup Screen allows
selection of one of four factory set
frequency groups (Groups A through
D), two user programmable frequency groups (Groups U and V) or
the choice to not use groups at all.
In the four factory set frequency groups, eight frequencies per group are preselected. These frequencies are
chosen to be free of intermodulation products. (See
Frequency Coordination.)
TUNING
NORMAL
Rio Rancho, NM – USA

UCR511
In the two user programmable frequency groups, up to
16 frequencies can be programmed per group.
The Tuning Setup Screen only selects the tuning mode (NORMAL or
Group Tuning) and not the operating frequency. Actual operating
frequencies are chosen through the Frequency Window.
Note
If NORMAL tuning mode is selected, the SEL Up and
Down buttons select the operating frequency in single
channel (100 kHz) increments and the MENU+Up and
MENU+Down shortcuts tune in 16 channel (1.6 MHz)
increments.
There are two group tuning modes: factory present
groups (Grp A through D) and user programmable
frequency groups (Grp U and V).
In these modes, the SEL Up and Down buttons navigate
among the selected intermod-free frequencies in the
group and the MENU+Up and MENU+Down shortcuts
jump to the first and last frequencies in the group.
Also, a lower case a, b, c, d, u or v will be displayed to
the immediate left of the transmitter switch settings in the
Frequency Window. The letter identifies the selected
factory or user tuning group.
Any time the currently tuned frequency is not in the
current tuning group, the group tuning mode indicator
will blink. Any time the currently tuned frequency is in
the current turning group, the group tuning mode indicator will give a steady (non-blinking) indication.
If a factory tuning group has been selected, pressing
either the SEL Up or Down button will select the nearest
factory selected frequency in that group above or below
the current frequency.
User Programmable Frequency Group Behavior
The user programmable frequency groups work very
similar to the factory groups with a few exceptions. The
most obvious difference is the ability to add or remove
frequencies from the group. Less obvious is the behavior of a user programmable frequency group with only
one, or no entries.
A user programmable frequency group with only one
entry will only display that one frequency regardless of
how many times the SEL Up or Down buttons are
pressed (providing the MENU button is not pressed at
the same time).
A user programmable frequency group with no entries
reverts to non-group-mode behavior, i.e., access is
allowed to all 256 available frequencies in the selected
receiver module's frequency block. However, once a
frequency has been added to the tuning group, this
behavior changes to group-mode behavior where the
MENU button must be pressed and held while either the
SEL Up or Down buttons are pressed to access frequencies that are not part of the current tuning group.
Adding/Deleting User Programmable Frequency Group Entries
Each User Programmable Frequency Group (“u” or “v”) has
separate contents. It is suggested to review the section titled
Frequency Coordination prior to adding frequencies inorder to
minimize potential intermodulation problems.
Note
1. Start from the Frequency Window and verify
that a lower case “u” or “v” is present next to
the transmitter switch settings.
2. While pressing and holding the MENU button
press either the SEL Up or Down button to
move to one of the 256 available frequencies
in the block. Whenever the selection comes to
rest on a frequency that is in the current
group, the group tuning mode indicator (letter
"u" or "v") will give a steady indication. On
frequencies that are not in the group, the
indicator will blink.
3. To add or remove the displayed frequency
from the group, hold down the MENU button
while pressing and holding the SEL Up button.
The group tuning mode indicator will stop
blinking to show that the frequency has been
added to the group, or begin blinking to
indicate that the frequency has been removed
from the group.T

When leaving the scan mode, you are given the option of
using the frequency the unit was on before entering the
scan mode, or using the frequency just selected in the
scan mode. The display shows USE OLD and USE
NEW to prompt you to make a frequency selection. To
accept the new frequency just selected in the scan
mode, press the DOWN button for USE NEW. To return
to the frequency you were using before entering the scan
mode, press the UP button for USE OLD. (The MENU

UCR511
ANTENNA USE AND PLACEMENT
The receiver is supplied with two straight BNC antennas.
In some circumstances remote antennas such as the
SNA600 or ALP700 may be useful for improving reception. Position remote antennas at least three or four feet
apart and so that they are also not within three or four
feet of large metal surfaces. If this is not possible, try to
position the antennas so that they are as far away from
the metal surface as is practical. It is also good to
position the receiver so that there is a direct “line of
sight” between the transmitter and the receiver antenna.
In situations where the operating range is less than
about 100 feet, the antenna positioning is much less
critical. The antennas can also be configured with one
whip mounted directly onto the panel of the receiver, and
the other one mounted remotely.
Be careful about the length of cabling from antenna to receiver.
Long cable runs can have serious signal loss. Lectrosonics has in-
line RF amplifiers suitable for compensating for long cable runs.
Contact your dealer or the factory for more information.
Note
A wireless transmitter sends a radio signal out in all
directions. This signal will often bounce off nearby walls,
ceilings, etc. and a strong reflection can arrive at the
receiver antenna along with the direct signal. If the
direct and reflected signals are out of phase with each
other a cancellation may occur. The result would be a
“dropout.” A dropout sounds like either audible noise
(hiss), or in severe cases, may result in a complete loss
of the carrier and the sound when the transmitter is
positioned in certain locations. A UHF dropout normally
sounds like a very brief “hiss” or a “swishing” sound.
Moving the transmitter (or the receiver’s antennas) even
a few inches will change the sound of the dropout, or
eliminate it. A dropout situation may be either better or
worse as the crowd fills and/or leaves the room, or when
the transmitter or receiver is operated in a different
location.
The receiver offers a sophisticated diversity design which
overcomes dropout problems in almost any situation. In
the event, however, that you do encounter a dropout
problem, first try moving the receiver’s antennas at least
three or four feet from their original location. This may
alleviate the dropout problem at that location. If dropouts
are still a problem, try moving the unit to an entirely
different location in the room or moving the receiver if
antennas are attached, or the receiver’s antennas in
closer to the transmitter location.
Lectrosonics transmitters radiate power very efficiently,
and the receivers are very sensitive. This reduces
dropouts to an insignificant level. If, however, you do
encounter dropouts frequently, call the factory or consult
your dealer. There is probably a simple solution.

INSTALLATION AND OPERATING INSTRUCTIONS
1. Install a fresh battery or connect an external
power source to the UCR511 and attaach the
antennas.
2. Unless frequency settings have been
previously assigned, scan for an open
frequency and set both the receiver and
transmitter to that frequency. (See Finding
Clear Frequencies.)
3. Connect the audio cable to the Receiver Audio
Out XLR jack.
4. Set the Power ON/OFF switch to ON and
verify that the LCD panel activates.
5. Adjust the transmitter gain.
THIS IS
PERHAPS THE MOST IMPORTANT STEP IN
THE SET UP PROCEDURE.
Refer to your
transmitter manual’s Operating Instructions
section for details on how to adjust the
transmitter gain. In general, adjust the
transmitter gain so that the voice peaks will
cause the audio modulation indicators on the
receiver and transmitter to show full
modulation on the loudest peak audio levels.
Normal levels should cause the UCR511’s
audio level icon to fluctuate fully. This will
result in the best possible signal to noise ratio
for the system.
A common mistake at this point is to use the transmitter audio gain
control to set the overall audio level of the entire audio system. The
transmitter gain control is not a volume control and must be set
independently of the overall system audio level. The transmitter
gain control is only used to set the proper modulation of the
transmitter. To explain it another way, it is used to match the
transmitter to the type of microphone and the sound levels that will
be present at that microphone. We encourage users to either
disconnect the rest of the sound system or turn the sound system
gain to minimum to prevent feedback or overload as the transmitter
gain is set. That way, feedback from the sound system or overload of
other equipment does not get in the way of setting the transmitter
gain properly. Only after the transmitter gain control is set should
the gain of the rest of the audio system be adjusted to achieve the
desired sound or signal levels.
Note
6. Adjust the Audio Output according to the type
of input on your equipment. Use the LEVEL
menu and adjust the level with the SELECT
Up and Down buttons The input levels of
different cameras, VCRs, and PA equipment
vary, which may require that you adjust the
AUDIO OUT to an intermediate position. Try
different settings and listen to the results. If
the output of the receiver is too high, you may
hear distortion or a loss of the natural
dynamics of the audio signal. If the output is
too low, you may hear steady noise (hiss)
along with the audio. The UCR511 audio
output is designed to drive any audio input

and the word “UNLOCKED” is displayed on the LCD
screen. When the unit is UNLOCKED, all settings can be
altered.
The UCR511 can only be LOCKED or UNLOCKED from
any of the main windows. (There are four of them.)
Also, it cannot be switched between LOCKED and
UNLOCKED modes when it is in a scanning mode or
from other subordinate screens.

TO REPLACE THE BATTERIES
Lift and open the bottom battery door cover with your
thumb, rotate the door until it is perpendicular with the
case and allow the batteries to fall out of the compartment into your hand. It is difficult to install a battery
backwards. Observe the large and small holes in the
battery contact pad before inserting new batteries.
Insert the contact end of the battery first, making sure
the contacts are aligned with the holes in the contact
pad, and then swing the door closed. You will feel it snap
into place when it is fully closed.

discharge. Be sure to remove lithium batteries as soon as possible
after warnings. If lithium batteries are allowed to fully discharge
while still inside the battery compartment, they will be very difficult
to remove.
Stuck lithium batteries can be avoided by removing the label
wrapping around the battery before use. This will allow the battery
to swell but will still leave enough room in the compartment for the
battery to fall out normally.

Frequency Coordination
Intermodulation interference is a problem constantly
lurking in the background, especially when working in
environments were multiple productions are taking place
simultaneously in relative close proximity. In these
cases, proper frequency coordination is a must. There
are basically three methods coordinate frequencies:
Use the Compatible Frequency Chart
Scan for clear channels (See Frequency Scan Mode
and Using The Scan Function)
Call Lectrosonics
Compatible Frequency Chart
The Compatible Frequency Chart was designed to assist
in minimizing intermodulation problems for multiple
channel wireless systems. It does this by identifying
potential intermodulation problems and listing compatible
frequencies and frequency groups. This chart can be
used with all Digital Hybrid Wireless
™
receivers.
The Compatible Frequency Chart divides the frequency
blocks used in the North American market into Row 1
and Row 2, then further divides each row into two groups
of eight frequencies each. These frequency groups are
Compatible Frequency Chart
labeled A and B and C and D, and correspond to the
factory set frequency groups (Groups A, B, C and D)
described in the Tuning Setup Screen. (See Compatible
Frequency Chart.)
Understanding and using the Compatible Frequency
Chart is not as difficult as it first appears. There are a
few basic rules to follow:
Refer to the Compatibility Frequency Chart's Compatible and
Incompatible frequency combinations. (Only frequency blocks 21
and 22 are shown for illustrative purposes.)
Note
Rule No. 1
Row 1 and Row 2 live in two different worlds. The
frequencies in Row 1 are not compatible with the frequencies in Row 2. If you are forced to use frequencies
from Row 1 with frequencies from Row 2, be aware that
intermodulation problems may exist.
Rule No. 2
Frequencies within an individual frequency block in the
same row are compatible. For example, all 16 frequencies within Row 1, Block 21 are compatible, and all

UCR511
frequencies in Row 2 Block 21 are compatible. However,
frequencies in Row 1, Block 21 are not compatible with
the frequencies in Row 2, Block 21. If possible, it is
highly recommeneded to choose frequencies that are in
the same row and same group. For example, stick with
frequencies in Row 1 Group A, or Row 2 Group D rather
than choosing frequencies from Row 1 Groups A and B.
Rule No. 3
Some frequencies in adjacent blocks are compatible and
some are not. Refer to the illustration to the left which
shows compatible and incompatible frequency relationships.
By following the three rules, it is possible to locate a
number of potential clear operating frequencies early in
the production that are intermodulation free, then refine
the list during system setup.
Using the Scan Function
Refer to the section titled "Frequency Scan Mode" for
details on how to use the built-in spectrum scanner.
Interference can result from a wide variety of sources
including TV station signals and other wireless equipment in use nearby. The RF spectrum analyzer built into
the UCR511 scans the frequency block to identify
channels with little or no interference. After scanning
and finding the needed number of clear channels, one
final procedure is necessary to verify the compatibility of
the chosen frequencies.
Turn on all transmitters and receivers used for the
program and verify there is a strong RF signal for each
receiver. Turn each transmitter off one at a time and
observe the RF level indicator on the matching receiver.
The RF level should disappear or drop to a very low
level. If it does not, change frequency on that receiver
and transmitter and try it again.
Any time a frequency is changed on any of the systems
in use, you must start at the beginning and go through
this procedure for all systems. This will test for higher
order imtermodulation from all signal sources and avoid
interference.
Call Lectrosonics
Lectrosonics uses a proprietary computer program to
perform thousands of calculations and identify various
interfering signals. Potential problems and trouble areas
can be identified in advance, and proposed new frequencies or other solutions can be suggested. This service is
offered to authorized Lectrosonics dealers and other
customers who are using LECTRO™ or Lectrosonics
wireless microphone and wireless IFB systems.

TROUBLESHOOTING
Symptom Possible Causes
INITIAL POWER ON
LCD display not active or lit. External power supply disconnected or inadequate.
Main power supply fuse tripped. Turn the receiver off, remove the
cause of the overload and turn the receiver back on.
Wrong polarity power source. The external DC in requires
POSITIVE to be on the center pin.
Battery may be low. Try a fresh battery
Version message shows DSP or COM. This indicates an internal error. Please contact the factory for
assistance.
Display indicates CHECK FREQ.
This is a warning that a strong signal is present but it’s far enough
away from the center of the channel that the audio is likely to be
distorted. Try relocating to unused frequencies. If this doesn’t
remove the warning mesasge, the transmitter or receiver may
need repair.
PILOT TONE SQUELCH
PILOT indicator is solid “P”,
but no sound Audio output cable bad or disconnected.
Audio Output level set too low. Use the built-in test tone to verify
levels.
PILOT “P” keeps flashing when
transmitter audio switch is turned on Pilot tone detection can take several seconds. Turn on the
transmitter power (and the audio switch on some models) and
wait 3 to 5 seconds for the “P” to indicate steadily.
Transmitter and receiver not on same frequency.
Receiver compatibility mode does not match the trasmitter in use.
(See Menu Selections from Main Window, COMPAT.)
Noise on audio and Pilot indicator is “b” The pilot tone bypass has been activated. Hold MENU and press
UP to reset (works only from the Main Window).
Pilot indicator not present but audio is being received
Receiver is set to a compatibility mode that doesn’t use Pilot Tone.
Check that receiver compatibility mode matches the transmitter
in use as any sufficiently strong signal can unsquelch the
receiver in this mode, compatible or not.
In the 500 Series and 300 Series compatibility modes, the
PILOT indicator on the front panel shows as a solid “P” to
indicate that the audio has been turned on at the
transmitter, and that the audio output on the receiver is
enabled. When the “P” is on, the audio is enabled. If the
“P” is flashing the pilot tone is not detected and the audio
In the other compatibility modes, no pilot tone is used and
the “P” is never displayed. Audio is present whenever the
receiver detects a sufficiently strong signal.
Regardless of the compatibility mode, activating the “pilot
bypass” function causes a lowercase “b” to appear in the
pilot indicator position on the main window and forcibly
will be muted (squelched).
NOTE:
unsquelches the audio.
ANTENNAS AND RF SIGNAL STRENGTH
RF Level is weak Receiver may need to be moved or reoriented.
Antenna on transmitter may be defective or poorly connected -
double check antenna on transmitter.
Improper length of antenna, or wrong antenna on transmitter or
receiver. UHF whip antennas are generally about 3 to 5 inches

UHF Wireless Digital HybridTM Receiver
long. UHF helical antennas may be shorter, but are often less
efficient.
No RF Signal Make certain frequency switches on transmitter match the
receiver frequency setting.
Check battery in transmitter
AUDIO SIGNAL QUALITY
Poor signal to noise ratio Transmitter gain set too low
The noise may not be in the wireless system. Turn the transmitter
audio gain all the way down and see if the noise remains. If the
noise remains, then turn the power off at the transmitter and see
if it remains. If the noise is still present, then the problem is not
in the transmitter.
If noise is still present when the transmitter is turned off, try
lowering the audio output level on the UCR511 and see if the
noise lowers correspondingly. If the noise remains, the problem
is not in the receiver.
Receiver output is too low for the input of the device it is feeding.
Try increasing the output level of the UCR511 and lowering the
input gain on the device the UCR511 is feeding.
Distortion
Transmitter input gain too high. Check and/or readjust input gain on
transmitter according to the LEDs on the transmitter and then
verify the setting with the audio meter in the main window.
Audio output level too high for the device the UCR511 is feeding.
Lower the output level of the UCR511.
Bad frequency response or generally
poor audio quality. Ensure the receiver is set to the compatibility mode that matches
the transmitter in use.
