Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM Introduction The 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 analog wireless systems. Along with providing peerless audio quality with wide frequency response and dynamic range in Nu Hybrid mode, the technology used in the SMWB transmitter includes compatibility modes for Lectrosonics Mode 3 and IFB receivers. The housing is a rugged, machined aluminum pack-

age 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 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. 4 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 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 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 trans-

mit 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 re-

quired 44.1kHz rate used for the digital hybrid algo-

rithm). The micro SDHC card also offers easy firmware update capabilities without the need for a USB cable or driver issues. SMWB SeriesLECTROSONICS, INC. Features Modulation Indicators Indicates micro SDHC card present and recording status (stopped/not recording) REC

-20 0 Battery Status LED microSDHC memory card port microSDHC memory card port Antenna Port Audio Input Jack Antenna Port Audio Input Jack 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. 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. 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. See page 20. Do this if you experience a drop in battery life or an increase in operating tempera-

ture. 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 incor-

rectly, the door may close but the unit will not operate. 5 Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM Turning Power ON Short Button Press will turn the unit on in the Standby Mode with When the unit is turned off, a short press of the power button the RF output turned off.

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 select-

ed 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 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.

(See page 7.) Adjusting the Input Gain The 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 Less than -20 dB

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. Gain Freq Rolloff Compat Gain 25

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. 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 Frequency The setup screen for frequency selection offers several ways to browse the available frequencies. Gain Freq Rolloff Compat Freq. b 19 51 494.500 Press MENU/

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 compat-

ibility with receivers that tune across a single band. The band number and hex code must match the receiver to enable the correct pilot tone.

Microphone RF Bypassing Line Level Signals 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 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 SCC330P All Lectrosonics lavaliere mics are already bypassed and do not need any additional capacitors installed for proper operation. 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. Line Level Normal Wiring Line Level More Headroom

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 occasions, you might need to update the bootloader. WARNING: Updating the bootloader can corrupt your unit if interrupted. Dont 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. Firmware Update Firmware 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 2. 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. Open the battery door and remove the memory card. 6) 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. 18 SMWB SeriesLECTROSONICS, INC. Recovery Process In 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 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 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 Successful 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 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. 19 Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM 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 thumb-

screw. 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 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. 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 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. With improved conductivity (lower resistance) more of the battery voltage can get to the internal power sup-

plies 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 thumb-

screw 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. 20 SMWB SeriesLECTROSONICS, INC. Straight Whip Antennas Antennas are supplied by the factory according to the following table:

(pkg of two) 23 Digital Hybrid Wireless Belt-Pack TransmittersRio Rancho, NM Android The Android version keeps all settings on the same page and allows the user to toggle between the activa-

tion 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. 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 transmit-

ters by delivering encoded audio tones to the micro-

phone attached to the transmitter. When the tone enters the transmitter, it is decoded to make a change to a va-

riety of different settings such as input gain, frequency and a number of others. The app was released by New Endian, LLC in Septem-

ber 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 se-

quence 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 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 versions default orientation is upside-down but can be configured to orient right-side up. The purpose for this is to orient the phones speaker, which is at the bot-

tom of the device, closer to the transmitter microphone. 24 SMWB SeriesLECTROSONICS, INC. Troubleshooting Symptom:
