Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 5IntroductionThe design of the SMWB transmitter delivers the ad-vanced technology and features of Digital Hybrid Wire-less® 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 ana-log wireless systems. DSP “compatibility modes” allow the transmitter to also be used with a variety of analog receivers by emulating the compandors found in earlier Lectrosonics analog wireless and IFB receivers, and certain receivers from other manufacturers (contact the factory for details).The housing is a rugged, machined aluminum package. The input jack is a standard Lectrosonics 5-pin type for use with electret lavaliere mics, dynamic mics, musi-cal 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 two AA batteries. The antenna port uses a standard 50 ohm SMA connector.The switching power supplies in the provide constant voltages to the transmitter circuits from the beginning to the end of battery life, with output power remaining con-stant 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 informa-tion in digital form, at the cost of some combination of power, bandwidth, operating range and resistance to interference.The Lectrosonics Digital Hybrid Wireless system over-comes 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 informa-tion 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 in-creased 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 WiringThe 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 sev-eral 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 instru-ments and line level signal sources.DSP-controlled Input LimiterThe 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 functionThe 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 trans-mit functions are exclusive of each other - you cannot record AND transmit at the same time. 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 SD card also offers easy firmware update capabilities without the need for a USB cable or driver issues.
SMWB SeriesLECTROSONICS, INC.6FeaturesBattery Status LED IndicatorAA 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.Modulation Indicators Battery Status LED-40 -20 0RECAudio Input JackAntenna PortAntenna PortAudio Input JackmicroSDHC memory card portmicroSDHC memory card port
Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 7Battery InstallationThe transmitter is powered by two AA batteries. We recommend using lithium for longest life. Because some batteries run down quite abruptly, using the Power LED to verify battery status will not be reli-able. 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. Do this if you experience a drop in bat-tery life or an increase in operating temperature. Insert the batteries according to the markings on the back of the housing. If the batteries are inserted incor-rectly, the door may close but the unit will not operate.*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.

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.Using Line Level and Instrument Inputs Line level signals can be sent to the input with the proper wiring. Refer to the section on Input Jack Wir-ing for Different Sources for details.Helpful Features on ReceiversTo aid in finding clear frequencies, several Lectrosonics receivers offer a SmartTune feature that scans the tun-ing 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 func-tion allow the receiver to set frequency, step size and compatibility modes on the transmitter via an infrared link between the two units.
Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 15Adjusting the Input GainThe two bicolor Modulation LEDs on the control panel provide a visual indication of the audio signal level entering the transmitter. The LEDs will glow either red or green to indicate modulation levels as shown in the following table.Signal Level -20 LED -10 LEDLess than -20 dB Off Off-20 dB to -10 dB Green Off-10 dB to +0 dB Green Green+0 dB to +10 dB Red GreenGreater than +10 dB Red RedNOTE: 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 en-ter 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 Turn-ing Power ON and OFF).2) Navigate to the Gain setup screen.GainFreqRolloffCompat -40 -20 0Gain253) Prepare the signal source. Position a microphone the way it will be used in actual operation and have the user speak or sing at the loudest level that will occur during use, or set the output level of the in-strument or audio device to the maximum level that will be used.4) Use the and arrow buttons to adjust the gain until the –10 dB glows green and the –20 dB LED starts to flicker red during the loudest peaks in the audio.5) Once the audio gain has been set, the signal can be sent through the sound system for overall level adjustments, monitor settings, etc. 6) If the audio output level of the receiver is too high or low, use only the controls on the receiver to make adjustments. Always leave the transmitter gain ad-justment set according to these instructions, and do not change it to adjust the audio output level of the receiver.Selecting FrequencyThe setup screen for frequency selection offers several ways to browse the available frequencies.Freq.b 19494.50051GainFreqRolloffCompatPress MENU/SEL to select one of four fields to make adjustmentsEach field will step through the available frequencies in a different increment.

Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 21Microphone RF BypassingWhen 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 wire-less 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 sig-nal from affecting the capsule, even though the trans-mitter input circuitry is already RF bypassed.If the mic is wired as directed, and you are having dif-ficulty 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 pos-sible, or if you are still having problems, capacitors can be installed on the mic pins inside the TA5F connec-tor 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 SCC330PAll Lectrosonics lavaliere mics are already bypassed and do not need any additional capacitors installed for proper operation.CAPSULE CAPSULE SHIELD AUDIO SHIELD AUDIO BIAS TA5F CONNECTOR TA5F CONNECTOR 2-WIRE MIC 3-WIRE MICCapacitors next to mic capsuleCapacitors in TA5F connectorLine Level SignalsThe wiring for line level and instrument signals is:• Signal Hot to pin 5• Signal Gnd to pin 1• Pin 4 jumped to pin 1This 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.See Fig. 8 on previous pageLine Level Normal WiringLine LevelMore Headroom(20 dB)
SMWB SeriesLECTROSONICS, INC.22Firmware UpdateFirmware updates are made using a microSDHC memory card. Download and copy the following firm-ware 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 Win-dows-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 Win-dows (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:1) Leave the SMWB turned off and insert the microS-DHC memory card into the slot. 2) Hold down both the UP and DOWN arrow buttons on the recorder and turn the power on.3) 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 3. You were not properly pressing UP, DOWN and Power at the same time.4) 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.5) When the update is complete, the LCD will display this message: UPDATE SUCCESSFUL REMOVE CARD. After the card is removed, the LCD will return to the three options shown in step 4 above.6) Select Power Off and press MENU/SEL to finish the update.7) If you re-insert the update card and turn the power back on for normal use, the LCD will display a mes-sage prompting you to format the card: Format Card? (files lost) • No • Yes 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 re-move the card at this time.The firmware update process is managed by a boot-loader program - on very rare occasion, you might need to update the bootloader.• smwbboot vX_xx.ldr is the bootloader fileFollow the same process as with a firmware update and select the smwbboot file. Be forewarned, this can cor-rupt your unit if interrupted. Don’t update the bootloader unless advised to do so by the factory (not for the faint of heart).
Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 23Recovery ProcessIn the event of a battery failure while the unit is re-cording, 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 FoundThe LCD message will ask:Recover? for safe use see manualYou 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 record-ing. 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 SuccessfulSpecial 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 previ-ously). 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 produc-tion editing software at a later time.
