Introduction
The design of the SMWB transmitter delivers the advanced technology and features of Digital Hybrid Wireless® in a Lectrosonics belt-pack transmitter at a modest cost. Digital Hybrid Wireless® combines a 24-bit digital audio chain with an analog FM radio link to eliminate a compandor and its artifacts, yet preserve the extended operating range and noise rejection of the finest analog wireless systems.
The housing is a rugged, machined aluminum package with a standard Lectrosonics 5-pin input jack for use with electret lavaliere mics, dynamic mics, musical instrument pickups and line level signals. The LEDs on the keypad allow quick and accurate level settings without having to view the receiver. The unit is powered by AA batteries, one battery in the SMWB and two in the SMDWB. The antenna port uses a standard 50 ohm SMA connector.
Switching power supplies provide constant voltages to the transmitter circuits from the beginning to the end of battery life, with output power remaining constant over the life of the battery. The input amplifier uses an ultra low noise op amp. Input gain is adjustable over a 44 dB range, with a DSP- controlled dual envelope input limiter providing a clean 30 dB range to prevent overload from signal peaks.
About Digital Hybrid Wireless®
All wireless links suffer from channel noise to some degree, and all wireless microphone systems seek to minimize the impact of that noise on the desired signal. Conventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sending the audio information in digital form, at the cost of some combination of power, bandwidth, operating range and resistance to interference.
The Lectrosonics Digital Hybrid Wireless system overcomes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique which can be accomplished only in the digital domain.
Since the RF link between transmitter and receiver is FM, channel noise will increase gradually with increased operating range and weak signal conditions, however, the Digital Hybrid Wireles system handles this situation elegantly with rarely audible audio artifacts as the receiver approaches its squelch threshold.
In contrast, a purely digital system tends to drop the audio suddenly during brief dropouts and weak signal conditions. The Digital Hybrid Wireless system simply encodes the signal to use a noisy channel as efficiently and robustly as possible, yielding audio performance that rivals that of purely digital systems, without the power, noise and bandwidth problems inherent in digital

transmission. Because it uses an analog FM link, Digital Hybrid Wireless enjoys all the benefits of conventional FM wireless systems, such as excellent range, efficient use of RF spectrum, and long battery life.
Servo Bias Input and Wiring
The input preamp is a unique design that delivers audible improvements over conventional transmitter inputs. Two different microphone wiring schemes are available to simplify and standardize the configuration. Simplified 2-wire and 3-wire configurations provide several arrangements designed for use only with servo bias inputs to take full advantage of the preamp circuitry.
A line level input wiring provides an extended frequency response with an LF roll-off at 35 Hz for use with instruments and line level signal sources.
DSP-controlled Input Limiter
The transmitter employs a digitally-controlled analog audio limiter prior to the analog-to-digital converter. The limiter has a range greater than 30 dB for excellent overload protection. A dual release envelope makes the limiter acoustically transparent while maintaining low distortion. It can be thought of as two limiters in series, connected as a fast attack and release limiter followed by a slow attack and release limiter. The limiter recovers quickly from brief transients, so that its action is hidden from the listener, but recovers slowly from sustained high levels to keep audio distortion low and preserve short term dynamic changes in the audio.
Recorder function
The SMWB has a built in recording function for use in situations where RF may not be possible or to work as a stand alone recorder. The record function and transmit functions are exclusive of each other – you cannot record AND transmit at the same time. When the unit is transmitting and recording is turned on, the audio in the RF transmission will stop, but the battery status will still be sent to the receiver.
The recorder samples at 44.1kHz rate with a 24 bit sample depth. (the rate was selected due to the required 44.1kHz rate used for the digital hybrid algorithm). The micro SDHC card also offers easy firmware update capabilities without the need for a USB cable or driver issues.

Compatibility with microSDHC memory cards
Please note that the SMWB and SMDWB are designed for use with microSDHC memory cards. There are several types of SD card standards (as of this writing) based on capacity (storage in GB). SDSC: standard capacity, up to and including 2 GB ­ DO NOT USE! SDHC: high capacity, more than 2 GB and up to and including 32 GB ­ USE THIS TYPE. SDXC: extended capacity, more than 32 GB and up to and including 2 TB ­ DO NOT USE! SDUC: extended capacity, more than 2TB and up to and including 128 TB ­ DO NOT USE! The larger XC and UC cards use a different formatting method and bus structure and are NOT compatible with the recorder. These are typically used with later generation video systems and cameras for image applications (video and high resolution, high speed photography). ONLY microSDHC memory cards should be used. They are available in capacities from 4GB to 32GB. Look for the Speed Class 10 cards (as indicated by a C wrapped around the number 10), or the UHS Speed Class I cards (as indicated by the numeral 1 inside a U symbol). Also note the microSDHC Logo. If you are switching to a new brand or source of card, we always suggest testing first before using the card on a critical application. The following markings will appear on compatible memory cards. One or all of the markings will appear on the card housing and the packaging.

Battery Status LED Indicator
AA batteries can be used to power the transmitter.
The LED labeled BATT on the keypad glows green when the batteries are good. The color changes to red when the battery voltage drops down and stays red through most of the battery life. When the LED begins to blink red, there will be only a few minutes remaining.
The exact point at which the LEDs turn red will vary with battery brand and condition, temperature and power consumption. The LEDs are intended to simply catch your attention, not to be an exact indicator of remaining time.
A weak battery will sometimes cause the LED to glow green immediately after the transmitter is turned on, but it will soon discharge to the point where the LED will turn red or the unit will turn off completely.
Some batteries give little or no warning when they are depleted. If you wish to use these batteries in the transmitter, you will need to manually keep track of the operating time to prevent interruptions caused by dead batteries.
Start with a fully charged battery, then measure the time it takes for the Power LED to go out completely.
NOTE: The battery timer feature in many Lectrosonics receivers is very helpful in measuring battery runtime. Refer to the receiver instructions for details on using the timer.

Menu Shortcuts
From the Main/Home Screen, the following shortcuts are available:
· Record: Press the MENU/SEL + UP arrow simultaneously
· Stop Recording: Press the MENU/SEL + DOWN arrow simultaneously
NOTE: The shortcuts are only available from the main/home screen AND when a microSDHC memory card is installed.
IR (infrared) Sync
The IR port is for quick setup using a receiver with this function available. IR Sync will transfer the settings for frequency, step size and compatibility mode from the receiver to the transmitter. This process is initiated by the receiver. When the sync function is chosen on the receiver, hold the IR port of the transmitter near the IR port of the receiver. (There is no menu item available on the transmitter to initiate the sync.)
NOTE: If a mismatch exists between the receiver and transmitter, an error message will appear on the transmitter LCD stating what the problem is.

Battery Installation
The transmitter is powered by AA batteries. (The SMWB requires one AA battery and the SMDWB requires two.) We recommend using lithium for longest life.
WARNING: Risk of explosion if the battery is replaced by an incorrect type.
Because some batteries run down quite abruptly, using the Power LED to verify battery status will not be reliable. However, it is possible to track battery status using the battery timer function available in Lectrosonics Digital Hybrid Wireless receivers.
The battery door opens by simply unscrewing the knurled knob part way until the door will rotate. The door is also easily removed by unscrewing the knob completely, which is helpful when cleaning the battery contacts. The battery contacts can be cleaned with alcohol and a cotton swab, or a clean pencil eraser. Be sure not to leave any remnants of the cotton swab or eraser crumbs inside the compartment.
A small pinpoint dab of silver conductive grease* on the thumbscrew threads can improve battery performance and operation. See page 20. Do this if you experience a drop in battery life or an increase in operating temperature.
If you are unable to locate a supplier of this type of grease – a local electronics shop for example – contact the factory for a small maintenance vial.
Insert the batteries according to the markings on the back of the housing. If the batteries are inserted incorrectly, the door may close but the unit will not operate.
Formatting SD Card
New microSDHC memory cards come pre-formatted with a FAT32 file system which is optimized for good performance. The PDR relies on this performance and will never disturb the underlying low level formatting of the SD card. When the SMWB/SMDWB “formats” a card, it performs a function similar to the Windows “Quick Format” which deletes all files and prepares the card for recording. The card can be read by any standard computer but if any write, edit or deletions are made to the card by the computer, the card must be re-formatted with the SMWB/SMDWB to prepare it again for recording. The SMWB/SMDWB never low level formats a card and we strongly advise against doing so with the computer.
To format the card with the SMWB/SMDWB, select Format Card in the menu and press MENU/SEL on the keypad.

IMPORTANT
The formatting of the SD card sets up contiguous sectors for maximum efficiency in the recording process. The file format utilizes the BEXT (Broadcast Extension) wave format which has sufficient data space in the header for the file information and the time code imprint.
The SD card, as formatted by the SMWB/SMDWB recorder, can be corrupted by any attempt to directly edit, change, format or view the files on a computer.
The simplest way to prevent data corruption is to copy the .wav files from the card to a computer or other Windows or OS formatted media FIRST. Repeat ­ COPY THE FILES FIRST!
Do not rename files directly on the SD card.
Do not attempt to edit the files directly on the SD card.
Do not save ANYTHING to the SD card with a computer (such as the take log, note files etc) – it is formatted for SMWB/SMDWB recorder use only.
Do not open the files on the SD card with any third party program such as Wave Agent or Audacity and permit a save. In Wave Agent, do not IMPORT – you can OPEN and play it but do not save or Import – Wave Agent will corrupt the file.
In short – there should be NO manipulation of the data on the card or addition of data to the card with anything other than an SMWB/SMDWB recorder. Copy the files to a computer, thumb drive, hard drive, etc. that has been formatted as a regular OS device FIRST – then you can edit freely.
iXML HEADER SUPPORT
Recordings contain industry standard iXML chunks in the file headers, with the most commonly used fields filled in.

WARNING: Do not perform a low level format (complete format) with a computer. Doing so may render the memory card unusable with the SMWB/SMDWB recorder.
With a windows based computer, be sure to check the quick format box before formatting the card.
With a Mac, choose MS-DOS (FAT).

Connecting the Signal Source
Microphones, line level audio sources, and instruments can be used with the transmitter. Refer to the section entitled Input Jack Wiring for Different Sources for details on the correct wiring for line level sources and microphones to take full advantage of the Servo Bias circuitry.

Turning Control Panel LEDs ON/OFF
From the main menu screen, a quick press of the UP arrow button turns the control panel LEDs on. A quick press of the DOWN arrow button turns them off. The buttons will be disabled if the LOCKED option is selected in the Power Button menu.
The control panel LEDs can also be turned on and off with the LED Off option in the Power Button menu.

Helpful Features on Receivers
To aid in finding clear frequencies, several Lectrosonics receivers offer a SmartTune feature that scans the tuning range of the receiver and displays a graphical report that shows where RF signals are present at different levels, and areas where there is little or no RF energy present. The software then automatically selects the best channel for operation.
Lectrosonics receivers equipped with an IR Sync function allow the receiver to set frequency, step size and compatibility modes on the transmitter via an infrared link between the two units.

NOTE: Full modulation is achieved at 0 dB, when the “-20″ LED first turns red. The limiter can cleanly handle peaks up to 30 dB above this point.

It is best to go through the following procedure with the transmitter in the standby mode so that no audio will enter the sound system or recorder during adjustment.

1. With fresh batteries in the transmitter, power the unit on in the standby mode (see previous section Turning Power ON and OFF).

2. Navigate to the Gain setup screen.

About Overlapping Frequency Bands
When two frequency bands overlap, it is possible to select the same frequency at the upper end of one and the lower end of the other. While the frequency will be the same, the pilot tones will be different, as indicated by the hex codes that appear.
In the following examples, the frequency is set to 494.500 MHz, but one is in band 470 and the other in band 19. This is done intentionally to maintain compatibility with receivers that tune across a single band. The band number and hex code must match the receiver to enable the correct pilot tone.

Selecting the Low Frequency Roll-off

It is possible that the low frequency roll-off point could affect the gain setting, so it’s generally good practice to make this adjustment before adjusting the input gain. The point at which the roll-off takes place can be set to:

· LF 35 35 Hz

· LF 100 100 Hz

· LF 50 50 Hz

· LF 120 120 Hz

· LF 70 70 Hz

· LF 150 150 Hz

The roll-off is often adjusted by ear while monitoring the audio.

Installing the Connector:

1. If necessary, remove the old connector from the microphone cable.

2. Slide the dust boot onto microphone cable with the large end facing the connector.

3. If necessary, slide the 1/8-inch black shrink tubing onto the mircrophone cable. This tubing is needed for some smaller diameter cables to ensure there is a snug fit in the dust boot.

4. Slide the backshell over the cable as shown above. Slide the insulator over the cable before soldering the wires to the pins on the insert.

5. Solder the wires and resistors to the pins on the insert according to the diagrams shown in Wiring Hookups for Different Sources. A length of .065 OD clear tubing is included if you need to insulate the resistor leads or shield wire.

6. If necessary, remove the rubber strain relief from the TA5F backshell by simply pulling it out.

7. Seat the insulator on the insert. Slide the cable clamp over the and of the insulator and crimp as shown on the next page.

8. Insert the assembled insert/insulator/clamp into the latchlock. Make sure the tab and slot align to allow the insert to fully seat in the latchlock. Thread the backshell onto the latchlock.

Digital Hybrid Wireless Belt-Pack Transmitters

Microphone RF Bypassing
When used on a wireless transmitter, the microphone element is in the proximity of the RF coming from the transmitter. The nature of electret microphones makes them sensitive to RF, which can cause problems with microphone/transmitter compatibility. If the electret microphone is not designed properly for use with wireless transmitters, it may be necessary to install a chip capacitor in the mic capsule or connector to block the RF from entering the electret capsule.
Some mics require RF protection to keep the radio signal from affecting the capsule, even though the transmitter input circuitry is already RF bypassed.
If the mic is wired as directed, and you are having difficulty with squealing, high noise, or poor frequency response, RF is likely to be the cause.
The best RF protection is accomplished by installing RF bypass capacitors at the mic capsule. If this is not possible, or if you are still having problems, capacitors can be installed on the mic pins inside the TA5F connector housing. Refer to the diagram below for the correct locations of capacitors.
Use 330 pF capacitors. Capacitors are available from Lectrosonics. Please specify the part number for the desired lead style.
Leaded capacitors: P/N 15117 Leadless capacitors: P/N SCC330P
All Lectrosonics lavaliere mics are already bypassed and do not need any additional capacitors installed for proper operation.

Line Level Signals
The wiring for line level and instrument signals is:
· Signal Hot to pin 5
· Signal Gnd to pin 1
· Pin 4 jumped to pin 1
This allows signal levels up to 3V RMS to be applied without limiting.
NOTE for line level inputs only (not instrument): If more headroom is needed, insert a 20 k resistor in series with pin 5. Put this resistor inside the TA5F connector to minimize noise pickup. The resistor will have little or no effect on the signal if the input is set for instrument.

Firmware Update
Firmware updates are made using a microSDHC memory card. Download and copy the following firmware update files to a drive on your computer.
· smwb vX_xx.ldr is the firmware update file, where “X_xx” is the revision number.
In the computer:

1. Perform a Quick Format of the card. On a Windows-based system, this will automatically format the card to the FAT32 format, which is the Windows standard. On a Mac, you may be given several options. If the card is already formatted in Windows (FAT32) – it will be greyed out – then you do not need to do anything. If the card is in another format, choose Windows (FAT32) and then click “Erase”. When the quick format on the computer is complete, close the dialogue box and open the file browser.
2. Copy the smwb vX_xx.ldr file to the memory card, then safely eject the card from the computer.
   In the SMWB:
3. Leave the SMWB turned off and insert the microSDHC memory card into the slot.
4. Hold down both the UP and DOWN arrow buttons on the recorder and turn the power on.
5. The recorder will boot up into the firmware update mode with the following options on the LCD:
   · Update – Displays a scrollable list of the .ldr files on the card.
   · Power Off – Exits the update mode and turns the power off.
   NOTE: If the unit screen shows FORMAT CARD?, power the unit off and repeat step 2. You were not properly pressing UP, DOWN and Power at the same time.
6. Use the arrow buttons to select Update. Use the UP and DOWN arrow buttons to select the desired file and press MENU/SEL to install the firmware. The LCD will display status messages while the firmware is being updated.
7. When the update is complete, the LCD will display this message: UPDATE SUCCESSFUL REMOVE CARD. Open the battery door and remove the memory card.
8. Re-attach the battery door and power the unit back on. Verify that the firmware version was updated by opening the Power Button Menu and navigating to the About item. See page 6.
9. If you re-insert the update card and turn the power back on for normal use, the LCD will display a message prompting you to format the card:
   Format Card? (files lost) · No · Yes
   18

If you wish to record audio on the card, you must re-format it. Select Yes and press MENU/SEL to format the card. When the process is complete, the LCD will return to the Main Window and be ready for normal operation.
If you choose to keep the card as is, you may remove the card at this time.
The firmware update process is managed by a bootloader program – on very rare occasions, you might need to update the bootloader.
WARNING: Updating the bootloader can corrupt your unit if interrupted. Don’t update the bootloader unless advised to do so by the factory.
· smwb_boot vX_xx.ldr is the bootloader file
Follow the same process as with a firmware update and select the smwbboot file.
Recovery Process
In the event of a battery failure while the unit is recording, a recovery process is available to restore the recording in proper format. When a new battery is installed and the unit is turned back on, the recorder will detect the missing data and prompt you to run the recovery process. The file must be recovered or the card will not be usable in the SMWB.
First it will read:
Interrupted Recording Found
The LCD message will ask:
Recover? for safe use see manual
You will have the choice of No or Yes (No is selected as the default). If you wish to recover the file, use the DOWN arrow button to select Yes, then press MENU/SEL.
The next window will give you the option to recover all or part of the file. The default times shown are the best guess by the processor where the file stopped recording. The hours will be highlighted and you can either accept the value shown or select a longer or shorter time. If you are unsure, simply accept the value shown as the default.
Press MENU/SEL and the minutes are then highlighted. You can increase or decrease the time to be recovered. In most cases you can simply accept the values shown and the file will be recovered. After you have made your time choices, press MENU/SEL again. A small GO! symbol will appear next to the DOWN arrow button. Pressing the button will initiate the file recovery. The recovery will happen quickly and you will see:
Recovery Successful
LECTROSONICS, INC.

Digital Hybrid Wireless Belt-Pack Transmitters

Special Note:
Files under 4 minutes long may recover with additional data “tacked on” to the end of the file (from previous recordings or data if the card had been used previously). This can be effectively eliminated in post with a simple delete of the unwanted extra “noise” at the end of the clip. The minimum recovered length will be one minute. For example, if the recording is only 20 seconds long, and you have selected one minute there will be the desired 20 recorded seconds with an additional 40 seconds of other data and or artifacts in the file. If you are uncertain about the length of the recording you can save a longer file – there will simply be more “junk” at the end of the clip. This “junk” may include audio data recorded in earlier sessions that were discarded. This “extra” information can be easily deleted in post production editing software at a later time.

Silver Paste on SM Series Transmitter Thumbscrews
Silver paste is applied to thumbscrew threads on new units at the factory to improve the electrical connection from the battery compartment through the housing on any SM Series transmitter. This applies to the standard battery door and the battery eliminator.
Threads provide electrical contact

Simply hold the cloth around the threads and turn the thumbscrew. Move to a new spot on the cloth and do it again. Do this until the cloth remains clean. Now, clean the threads in the case by using a dry cotton swab (Q-tip) or equivalent. Again, clean the case threads until a fresh cotton swab comes away clean.
Open the vial, and transfer a pinhead speck of silver paste to the second thread from the end of the thumbscrew. A easy way to pickup a speck of paste is to partially unfold a paper clip and use the end of the wire to acquire a tiny bit of paste. A toothpick will also work. An amount that covers the end of the wire is sufficient.
Apply paste to second thread from end of thumbscrew

The small enclosed vial contains a tiny amount (25 mg) of silver conductive paste. A small speck of this paste will improve the conductivity between the battery cover plate thumbscrew and the case of the SM.

The tiny vial is about 1/2 inch tall and contains 25 mg of silver paste.

It is not necessary to spread the paste more than a little bit on the thread as the paste will spread itself every time the thumbscrew is screwed in and out of the case during battery changes.
Do not apply the paste to any other surfaces. The cover plate itself can be cleaned with a clean cloth by rubbing the slightly raised rings on the plate where it contacts the battery terminal. All you want to do is to remove any oils or dirt on the rings. Do not abrade these surfaces with a harsh material such as a pencil eraser, emery paper, etc., as this will remove the conductive nickel plating and expose the underlying aluminum, which is a poor contact conductor.

With improved conductivity (lower resistance) more of the battery voltage can get to the internal power supplies causing reduced current drain and longer battery life. Though the amount seems very small, it is enough for years of use. It is, in fact, 25 times the amount that we use on the thumbscrews at the factory.
To apply the silver paste, first completely remove the cover plate from the SM housing by backing the thumbscrew completely out of the case. Use a clean, soft cloth to clean the threads of the thumbscrew.
NOTE: Do NOT use alcohol or a liquid cleaner.

LectroRM
By New Endian LLC
LectroRM is a mobile application for iOS and Android smart phone operating systems. Its purpose is to make changes to the settings on select Lectrosonics transmitters by delivering encoded audio tones to the microphone attached to the transmitter. When the tone enters the transmitter, it is decoded to make a change to a variety of different settings such as input gain, frequency and a number of others.
The app was released by New Endian, LLC in September 2011. The app is available for download and sells for about $20 on the Apple App Store and Google Play Store.
The settings and values that can be changed vary from one transmitter model to another. The complete list of available tones in the app is as follows:
· Input gain
· Frequency
· Sleep Mode
· Panel LOCK/UNLOCK
· RF output power
· Low frequency audio roll-off
· LEDs ON/OFF
The user interface involves selecting the audio sequence related to the desired change. Each version has an interface for selecting the desired setting and the desired option for that setting. Each version also has a mechanism to prevent accidental activation of the tone.
iOS

is at the bottom of the device, closer to the transmitter microphone.
Android
The Android version keeps all settings on the same page and allows the user to toggle between the activation buttons for each setting. The activation button must be pressed and held to activate the tone. The Android version also allows users to keep a configurable list of full sets of settings.
Activation
For a transmitter to respond to remote control audio tones, the transmitter must meet certain requirements:
· The transmitter must be turned on. · The transmitter must have firmware version 1.5 or later for Audio, Frequency, Sleep and Lock changes. · The transmitter microphone must be within range. · The remote control function must be enabled on the transmitter.
Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com.

The iPhone version keeps each available setting on a separate page with the list of options for that setting. On iOS, the “Activate” toggle switch must be enabled to show the button which will then activate the tone. The iOS version’s default orientation is upside-down but can be configured to orient right-side up. The purpose for this is to orient the phone’s speaker, which

Troubleshooting

It is important that you follow these steps in the sequence listed.

Symptom:

Possible Cause:

Transmitter Battery LED off when Power Switch “ON”

1. Batteries are inserted incorrectly. 2. Batteries are low or dead.

No Transmitter Modulation LEDs when Signal Should be Present

1. Gain control turned all the way down. 2. Batteries are inserted incorrectly. Check power LED. 3. Mic capsule is damaged or malfunctioning. 4. Mic cable damaged or miswired. 5. Instrument Cable damaged or not plugged in. 6. Musical instrument output level set too low.

Receiver Indicates RF But No Audio

1. Audio source or cable connected to transmitter is defective. Try using an alternate source or cable.
2. Make sure the compatibility mode is the same on transmitter and receiver.
3. Ensure musical instrument volume control is not set to minimum.
4. Check for correct pilot tone indication on the receiver. See item on page 16 entitled About Overlapping Frequency Bands.

Receiver RF Indicator Off

1. Ensure that the transmitter and receiver are set to the same frequency, and that the hex code matches.
2. Transmitter not turned on, or battery is dead. 3. Receiver antenna missing or improperly positioned. 4. Operating distance is too great. 5. Transmitter may be set to the Standby Mode. See page 8.

No Sound (Or Low Sound Level), Receiver Indicates Proper Audio Modulation

1. Receiver output level set too low. 2. Receiver output is disconnected; cable is defective or miswired. 3. Sound system or recorder input is turned down.

Distorted Sound

1. Transmitter gain (audio level) is too high. Check Modulation LEDs on transmitter and receiver while distortion is being heard.
2. Receiver output level may be mismatched with the sound system or recorder input. Adjust output level on receiver to the correct level for the recorder, mixer or sound system.
3. Transmitter and receiver may not be set to the same compatibility mode. Some mis-matched combinations will pass audio.
4. RF interference. Reset both transmitter and receiver to a clear channel. Use scanning function on receiver if available.

Wind Noise or Breath “Pops'”

1. Reposition microphone, or use a larger windscreen, or both.
2. Omni-directional mics produce less wind noise and breath pops than directional types.

Hiss and Noise — Audible Dropouts

1. Transmitter gain (audio level) far too low. 2. Receiver antenna missing or obstructed. 3. Operating distance too great. 4. RF interference. Reset both transmitter and receiver to a
clear channel. Use scanning function on receiver if available. 5. Musical instrument output set too low. 6. Microphone capsule picking up RF noise. See item on page 21
entitled Microphone RF Bypassing.

Excessive Feedback (With Microphone)
Slow Card Warning While Recording Warning . REC
slow
OK card

1. Transmitter gain (audio level) too high. Check gain adjustment and/or reduce receiver output level.
2. Microphone too close to speaker system. 3. Microphone is too far from user’s mouth.
1. This error alerts the user to the fact that the card is unable to keep up with the speed at which the SMWB is recording data.
2. This creates tiny gaps in the recording. 3. This may present an issue when the recording is to be
synchronized with other audio or video.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
