ety of electret microphones used in professional appli-

cations has caused confusion and compromises in the wiring needed for wireless transmitters. To address this problem, the unique Servo Bias input circuit provides an automatically regulated voltage over a very wide range of current for compatibility with all microphones. Digital Hybrid Wireless Technology All wireless links suffer from channel noise to some de-

gree, and all wireless microphone systems seek to mini-

mize the impact of that noise on the desired signal. Con-

ventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (typically 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 and resistance to interference. Digital Hybrid systems overcome channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still send-

ing the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital imple-

mentation of an analog compandor but a technique that can be accomplished only in the digital domain, even though the inputs and outputs are analog. Because it uses an analog FM link, the Digital Hybrid system enjoys all the benefits of conventional FM wire-

less systems and it does away with the analog compan-

dor and its artifacts. The Digital Hybrid design results in a signal-to-noise ratio high enough to preclude the need for conventional pre-

emphasis (HF boost) in the transmitter and de-emphasis

(HF roll off) in the receiver. This eliminates the potential for distortion of signals with abundant high-frequency information. Low Frequency Roll-Off The low frequency roll-off can be set for a 3 dB down point at 35, 50, 70, 100, 120 and 150 Hz to control sub-

sonic and very low frequency audio content in the au-

dio. The actual roll-off frequency will vary slightly depend-

ing upon the low frequency response of the microphone. Excessive low frequency content can drive the transmit-

ter into limiting, or in the case of high level sound sys-

tems, can even cause damage to loudspeaker systems. The roll-off is normally adjusted by ear while listening as the system is operating. Input Limiter A DSP-controlled analog audio limiter is employed be-

fore the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection. A dual re-

lease envelope makes the limiter acoustically transpar-

ent while maintaining low distortion. It can be thought of as two limiters in series, a fast attack and release limiter followed by a slow attack and release limiter. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

ages to operate various circuit stages with maximum efficiency. The firmware remembers the power status when a battery fails, so the transmitter will be turned on auto-

matically when the battery is replaced and the previous settings will be enabled. Circulator/Isolator The RF output circuit includes a one way circulator/iso-

lator using a magnetically polarized ferrite. This device greatly reduces RF intermodulation produced when multiple transmitters are used in close proximity to one another (several feet apart). The isolator also provides additional RF output stage protection against static shock. In addition to controlling the limiter, the DSP also en-

codes the digitized audio from the A/D converter and adds an ultrasonic pilot tone to control the squelch in the receiver. A pilot tone squelch system provides a reli-

able method of keeping a receiver output muted (audio mute) even in the presence of significant interference. When the system is operating in the hybrid mode, a dif-

ferent pilot tone frequency is generated for each carrier frequency to prevent inadvertent squelch problems in multi-channel sytems. Microprocessor Control A microprocessor monitors user command inputs from the control panel buttons and numerous other internal signals. It works intimately with the DSP to ensure the audio is encoded according to the selected Compatibil-

ity Mode and that the correct pilot tone is added to the encoded signal. Compatibility Modes SM transmitters are designed to operate with Lectroson-

ics Digital Hybrid receivers and will yield the best per-

formance when doing so, however, due to the flexibility of digital signal processing, the transmitter can also operate with Lectrosonics IFB receivers in the same frequency band. Control Panel The control panel includes four membrane switches and an LCD screen to adjust the operational settings. Multi-

color LEDs are used to indicate audio signal levels for accurate gain adjustment and for battery status. Variable Power Output This advanced feature allows the operator to optimize the transmitter for maximum battery life, or for slightly increased operating range. Power output is selected us-

ing the LCD in a setup mode while the RF output of the transmitter is turned off. 5 Super-Minature Belt Pack TransmitterRio Rancho, NM Controls and Functions Modulation LEDs Battery Compartment Cover Plate LCD Battery Compartment Thumb Screw UP Arrow Antenna Jack Audio Input Jack DOWN Arrow PWR LED AUDIO Button FREQ Button LCD Screen The LCD is a numeric-type Liquid Crystal Display with screens for adjusting power, frequency, audio level and low frequency audio roll-off. The transmitter can be powered up with or without the RF output turned on. A countdown appears in the LCD when powering on and off, allowing the transmitter to be turned on without RF for adjustments, and to prevent accidentally turning it off with momentary button presses. Power LED The PWR LED glows green when the battery is good. The color changes to red at a midpoint of the runtime as the battery voltage drops. When the LED begins to blink red, there is usually less than 30 minutes remain-

ing with a lithium battery. The exact point at which the LED turns red will vary with battery brand and condition, temperature, and the out-

put power setting. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time. The illustration below depicts typical behavior with a lithium battery in the single battery model at 50 mW. Varies Green Red Blink e g a t l o V 1.6 1.4 1.2 1.0

.8 4 2 Hours 8 A weak battery will sometimes cause the PWR LED to glow green immediately after the transmitter is turned on, but will soon discharge to the point where the LED will turn red or the unit will turn off completely. 6 Power LED Off Feature In normal operating mode, the UP and DOWN arrow buttons may be used to turn the PWR LED indica-

tors off and on. This setting does not persist through a power cycle nor does it affect the LCD backlight. 6 Audio Input Jack The Servo Bias input circuitry accommodates virtually every lavaliere, handheld or shotgun microphone avail-

able, plus line level signals. Battery Compartment and Thumb Screw The large knurled thumbscrew is used to release or secure the Battery Compartment Cover Plate. Modulation LEDs Proper input gain adjustment is critical to ensure the best audio quality. Two bicolor LEDs will glow either red or green to accurately indicate modulation levels. The input circuitry includes a wide range DSP controlled limiter to prevent distortion at high input levels. It is important to set the gain (audio level) high enough to achieve full modulation during louder peaks in the audio. The limiter can handle over 30 dB of level above full modulation, so with an optimum setting, the LEDs will flash red during use. If the LEDs never flash red, the gain is too low. In the table below, +0 dB indicates full modulation (-20 LED just turns red). Signal Level

-10 LED AUDIO and FREQ Buttons The AUDIO button is used to display the audio level and low frequency roll-off settings. The UP and DOWN ar-

row buttons adjust the values. The FREQ Button displays the selected operating frequency and toggles the LCD between displaying the actual operating frequency in MHz and a two-digit hexadecimal number that corresponds to the equivalent frequency switch setting on legacy transmitters. Pressing both buttons simultaneously enters the standby mode and turns the unit on and off UP/DOWN Arrow Buttons The UP and DOWN arrow buttons are used to select the values on the various setup screens and to lock out the control panel. Antenna The transmitter uses a whip antenna with a flexible wo-

ven, galvanized steel mesh cable and a standard SMA connector. SMV SeriesLECTROSONICS, INC. Battery and Battery Eliminator Installation Note: Standard zinc-carbon batteries marked heavy-duty or long-lasting are not adequate. The battery status circuitry is designed for the voltage drop over the life of lithium batteries. To install new batteries:

1. Turn the battery cover plate thumbscrew counter-

clockwise a few turns until the door will rotate. 2. Insert the new batteries into the housing. Polarity is marked on the back of the housing. 3. Align the battery cover plate and tighten the battery cover plate thumbscrew. Attaching and Removing the Microphone The flexible sleeve over the 5-pin plug on the micro-

phone helps prevent dust and moisture from getting into the input jack, and provides additional strain relief. The flange around the rim of the connector on the transmitter creates a splash proof connection and keeps the sleeve securely attached. The following procedure simplifies the attachment and removal of the microphone to assure the sleeve is seated securely. Align the latch on the plug and jack and insert the connector. It is easier to attach the microphone when the sleeve is pulled back as shown in the Step 3 photo below. Cover plate thumbscrew Gore-Tex covered vent Do Not Cover Vent 1 Two battery compartments

Note: If the AUDIO and FREQ buttons are released before the LCD goes blank at the end of the countdown, the unit will not turn off. Instead, it will stay energized and the display will return to the previous screen. Standby Mode With the power turned off, pressing the AUDIO and FREQ buttons briefly places the unit in Standby Mode. Standby Screen In this mode the RF output is turned off so all setup adjustments can be made without interfering with other systems operating in the same location. The screen displays rf OFF to remind the user that the unit is not transmitting. While the unit is in the standby mode, access the setup screens using the AUDIO and FREQ buttons and make adjustments using the UP and DOWN arrows. 8 Menus Setup is accomplished using menus and setup screens accessed by holding the UP and DOWN arrow buttons at turn on, and by pressing the AUDIO and FREQ but-

tons when the unit is turned on. Hold UP arrow at turn on. Hold the UP arrow button in while pressing both AUDIO and FREQ buttons to access the setup screens below.

LF (XX) adjusts the low frequency roll-off of the audio signal. AUD (XX) adjusts the input gain LF (XX) - Adjusting the Low Frequency Roll-off Repeatedly press the AUDIO button until the LF roll-

off adjustment screen appears. Then press and hold the AUDIO button while selecting the desired roll-off frequency with the UP and DOWN arrows. The roll-off frequency can be set to 35, 50, 70, 100, 120 and 150 Hz. AUD (XX) - Adjusting Audio Level (Gain) The control panel modulation LEDs marked -10 and -20 indicate the audio level and limiter activity. Once adjust-

ed according to the following procedure, the transmit-

ters audio level setting should not be used to control the volume of your sound system or recorder levels. This gain adjustment matches the transmitter gain with the microphones output level, the users voice level and the position of the microphone. The audio input level

(gain) should be adjusted with the unit in the Standby Mode while observing the LEDs. It is generally best to set the LF roll-off before adjust-

ing the gain, since low frequency energy can affect the input level to the transmitter. It is desirable to to set the gain so that some limiting occurs on louder peaks. The limiter is very transparent over a 43 dB range, and its effect is not audible until the system is close to overload. In other words, dont be shy about turning up the gain. It is actually a good idea to turn the gain up to maxi-

mum and listen for distortion or compression to get a feel for how much headroom is available. Signal Level Less than -20 dB

vidual, adjust it for the loudest voice. 1) With the transmitter in the Standby Mode, plug in the microphone and make sure the connector is firmly seated. Warning: If the wireless system is powered up while connected to a live sound system, be careful to turn the sound system level down first or severe feedback can occur. 2) Position the microphone in the location where it will be used in actual operation. 3) Observe the modulation LEDs while speaking or singing into the microphone at the same voice level that will be used during operation. While holding the AUDIO button, press the UP or DOWN arrow buttons until the both the -20 and -10 LEDs glow green, with the -20 LED flickering red during louder peaks in the audio. This will maximize the signal to noise ratio of the system with full modulation. 4) If the unit was set up in Standby Mode, it will be necessary to turn the transmitter off, then power it up again in normal operation so the RF output will be on. Then the other components in the sound or recording system can be adjusted. 9 Super-Minature Belt Pack TransmitterRio Rancho, NM FREQ Button Remote Control Operation The transmitter can be controlled by signals from audio dweedle tones generated by a mobile phone, or with the Lectrosonics RM and RM2 devices. Remote Control Screens The remote function is enabled in the UP arrow power on options (see previous section). If a remote control signal is detected but the function is no enabled, the message rc oFF will be displayed briefly on the trans-

mitters LCD. Remote functions available are:

Tx Input Gain Sleep/Unsleep Lock/Unlock Frequency Tuning in 25 kHz steps Changing the low frequency roll-off setting Turning on/off the PWR and Audio LEDs In sleep mode, the transmitter uses about 20% of the normal amount of battery drain. Sleep mode can only be invoked with the remote control, and can only be revoked with the remote control or by removing the battery. When in the sleep mode, the PWR LED blinks green every few seconds to indicate that the transmitter is asleep and not turned off. Input gain functions The operating frequency can be adjusted according to the frequency in MHz or a two-digit hexadecimal code. Press the button repeatedly to switch between the two displays. The display switches when the button is first pushed; push and hold the button in the desired mode and use the UP and DOWN arrow buttons to make the adjustment. In this example, the same frequency is displayed in MHz and the equivalent hex code. The hex code is a hexadecimal sequence that pro-

gresses upward from lowest to highest frequency using the numerals and letters from 0 through F. When the frequency is on a 100 kHz step, the hex code is only two digits, as shown above, which is easy to remember. When the step size is set to 25 kHz, additional charac-

ters are used to denote the exact frequency with four characters. Locking/Unlocking the Control Panel Simultaneously pressing and holding both the UP and DOWN arrow buttons during normal operation starts the Lock timer. The timer starts at three and counts down to zero. When the timer reaches zero, the buttons on the control panel are locked. With the controls locked, the AUDIO and FREQ buttons can still be used to display current settings. Any attempt to change a setting by pressing either the UP or DOWN arrow button will result in an on-screen Loc reminder that the controls are locked. Remove the batteries to unlock the control panel. Important: Once the transmitter is locked, it cannot be unlocked or powered off using the buttons. The only ways to unlock a locked transmitter are to remove the battery or unlock it via the RM remote control. 10 SMV SeriesLECTROSONICS, INC. 5-Pin Input Jack Wiring The wiring diagrams included in this section represent the basic wiring necessary for the most common types of microphones and other audio inputs.

1) If necessary, remove old connector from microphone cable. 2) Slide Rubber Boot onto microphone cable with the large end facing away from the microphone. (See illus-

tration above.) 3) If necessary, slide the 1/8-inch black shrink tubing onto the mircrophone cable. (This tubing is needed for some cables to ensure the cable fits snugly in the rubber boot.) 4) Use the resistors and connector included with this kit to configure the TA5F to your particular microphone.

(See Wiring Diagrams below.) A length of .065 OD clear tubing is included if insulating the resistor leads or shield wire is necessary. (Remove rubber strain relief from connector backshell by pulling it out of the backshell.) 5) Slide the Strain Relief over the TA5F Insert and crimp as shown to the right. Then insert the TA5F Insert and Strain Relief in the TA5F Latchlock. Screw the TA5F Flex Relief onto the TA5F Latchlock. 6) If needed, position and shrink the 1/8-inch shrink tub-

ing on the microphone cable, then slide the Rubber Boot down over the TA5F connector. Line Level Signals The normal hookup for line level signals is: Signal Hot to pin 5, Signal Gnd to pin 1 and pin 4 jumped to pin 1. This allows signal levels up to 3V RMS to be applied without limiting. If more headroom is needed, insert a 20 k resistor in series with pin 5. Put this resistor inside the TA5F con-

nector to minimize noise pickup. SMKITTA5 Connector kit for SMV series transmitters, 5-pin TA5F plug with sleeve Insulator Strain Relief Insert TA5F Backshell with Strain Relief Remove strain relief if using dust boot TA5F Latchlock TA5F Backshell

Lectrosonics lavaliere microphones are terminated for compatibility with VHF and UHF transmitters, which is different than what is shown here. 12 SMV SeriesLECTROSONICS, INC. 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 the 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 signal from affecting the capsule, even though the transmitter input circuitry is already RF bypassed (see schematic diagram). 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 connector housing. 2 WIRE MIC 3 WIRE MIC Preferred locations for bypass capacitors SHIELD AUDIO CAPSULE TA5F CONNECTOR CAPSULE SHIELD AUDIO BIAS Alternate locations for bypass capacitors TA5F CONNECTOR Install the capacitors as follows: Use 330 pF capaci-

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 vial contains a tiny amount (25 mg) of silver conductive paste. A small speck of this paste will im-

prove the conductivity between the battery cover plate thumbscrew and the case of the transmitter. 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. 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. 15 Super-Minature Belt Pack TransmitterRio Rancho, NM 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 long pressed to activate. 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 not be turned off; it can how-

ever be in sleep mode. The transmitter must have a firmware version that includes the remote control functions. The remote control mode must be enabled in the setup screen. The transmitter microphone must be within range. Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com. LectroRM Android SM Series WM L Series By New Endian LLC LectroRM is a mobile application for iOS and Android operating systems. Its purpose is to remotely control Lectrosonics transmitters, including:

The app remotely changes settings on the transmit-

ter through the use of encoded audio tones, which when received by the attached microphone, will alter the configured setting. 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. LectroRMs remote control mechanism is the use of an audio sequence of tones (dweedles) that are inter-

preted by the transmitter as a configuration change. The settings available in LectroRM are:

Audio Input Gain Frequency Sleep/Unsleep Lock Mode Power Output Low Frequency Roll-off LEDs On/Off User Interface 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 audio. 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 devices speaker, which is at the bot-

tom of the device, closer to the transmitter microphone. 16 SMV SeriesLECTROSONICS, INC. Accessories for single battery models:
