Rule No. 1 ................................................................................................................................................................ 18
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

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.

This icon changes in size horizontally to indicate the audio level (modulation) of the signal received from the transmitter. The icon display will change to a solid rectangular block when the audio signal is being limited in the transmitter. Levels in dB are engraved into the bezel above the LCD.

BATTERY LEVELS

The icon above the Rx symbol indicates the receiver battery condition and will flash when approximately one hour of operating time is remaining. When external power is being used, the Rx battery icon changes to look like a power plug. The area above the Tx symbol features either a transmitter battery status icon or the transmitter battery timer, depending on the TXBAT setting. The transmitter battery status icon is available only in compatibility modes supporting battery telemetry (500 and 300 Series). In such cases, the transmitter battery status icon appears 5 to 10 seconds after the transmitter signal is acquired. If selected in the TXBAT setup screen, the transmitter battery timer is available in any compat­ibility mode. It accumulates hours and minutes that the communications link is active, retaining the timing even when the receiver is off. To reset the battery timer, hold MENU and DOWN together for one second.

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

To stop scanning, press the MENU button once. The scanning will stop immediately, and the display will switch to the VIEW window. In this window, each vertical band of the display represents eight frequencies (800 kHz). Pressing the SEL Up or Down buttons will scroll the cursor coarsely across the tuning range. The trans­mitter switch settings matching the frequency indicated by the cursor are shown in the upper right corner of the screen.
Spectrum data is collected only when the receiver is scanning. Successive scanning with repeated passes through the tuning range will accumulate the highest peaks encountered to aid in finding clear frequencies. To clear the scan memory without leaving scan mode, turn the power switch off and back on quickly.
Pressing the MENU button once will shift the display to the FINE VIEW window which will show an expanded portion of the spectrum around the cursor.

In addition to assessing the congestion within the RF tuning range of the receiver, the scanning mode is also used to find a clear operating frequency. Scroll through the screen and find a frequency where no RF signals are present (or in the worst case, only very weak RF sig­nals). With the cursor on this frequency, press the SEL Up, SEL Down and MENU buttons at the same time to leave the scan mode.
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 button defaults to USE OLD).
Once you leave the scan mode, the Frequency Window will be displayed. Set your transmitter switches to the same settings as shown on the display and your system will be ready for operation.

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

If the MENU button is released before the word “LOCKED” appears, the unit will remain UNLOCKED. When in a LOCKED state, the pilot tone bypass toggle is also defeated.
In LOCKED state, the use of the MENU and SEL Up/ Down buttons are limited to “view only” and any attempts to change selections will result in a LCD screen display­ing the word “LOCKED.” The unit cannot be used for RF scanning when it is set in the LOCKED state.
To UNLOCK the UCR511 - Press and hold the MENU button until a bar tracks horizontally across the screen 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.
