General Technical Description

The HMa transmitter uses a DSP controlled input limiter featuring a wide range dual envelope design which cleanly limits input signal peaks over 30 dB above full modulation. Switching power supplies to provide constant voltages to the transmitter circuits from the beginning (3 Volts) to the end (1.7 Volts) of battery life, and an ultra low noise input amplifier for quiet operation.

Digital Hybrid Wireless® Technology

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 commanders 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 and resistance to interference.

Lectrosonics Digital Hybrid Wireless systems overcome 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 that can be accomplished only in the digital domain, even though the inputs and outputs are analog.

Channel noise still impacts received signal quality and will eventually overwhelm a receiver. Digital Hybrid Wireless ^® simply encodes the signal to use a noisy channel as efficiently and robustly as possible, yielding audio performance that rivals that of wholly digital systems, without the power 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 resistance to interference. However, unlike conventional FM systems, it does away with the analog compandor and its artifacts.

No Pre-Emphasis/De-Emphasis

The Digital Hybrid Wireless ^® 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 on 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 subsonic and very low frequency audio content in the audio. The actual roll-off frequency will vary slightly depending upon the low frequency response of the microphone.

Excessive low frequency content can drive the transmitter into limiting, or in the case of high level sound systems, 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 before the analog-to-digital (A-D) converter. The limiter has a range of more 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, 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 and while preserving short term dynamics.

Signal Encoding and Pilot Tone

In addition to controlling the limiter, the DSP also encodes the digitized audio from the A-D converter and adds an ultrasonic pilot tone to control the receiver's squelch. A pilot tone squelch system provides a reliable method of keeping a receiver output muted (squelched) even in the presence of significant interference. When the system is operating in the hybrid mode, a different pilot tone frequency is generated for each carrier frequency in 100 kHz increments to prevent inadvertent squelch problems and simplify multi-channel coordination.

Microprocessor and DSP

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 Compatibility Mode and that the correct pilot tone is added to the encoded signal.

Compatibility Modes

The transmitter was designed to operate with Lectrosonics Digital Hybrid Wireless receivers and will yield the best performance when doing so. However, due to the flexibility of digital signal processing, the transmitters can also operate in various compatibility modes (vary per specific model) for use with Lectrosonics Mode 3 and IFB receivers. It will also work with certain non-Lectrosonics receivers. Contact your sales representative or the factory for a complete list of compatible non-Lectrosonics receivers.

Control Panel

The control panel includes four membrane switches and an LCD screen to adjust the operational settings. Multicolor LEDs are used to indicate audio signal levels for accurate gain adjustment and for battery status.

Controls and Functions

LCD Screen

The LCD is a numeric-type Liquid Crystal Display with several screens that allow settings to be made with the AUDIO and FREQ buttons, and the UP and DOWN arrow buttons to configure the transmitter. The transmitter can be turned on in a "standby" mode with the carrier turned off to make adjustments without the risk of interfering with other wireless systems nearby.

Power LED

The PWR LED glows green when the batteries are good. The color changes to red when there is about 20 minutes of life left. When the LED begins to blink red, there are only a few minutes of life.

A weak battery will sometimes cause the PWR LED to glow green immediately after being put into the unit, but will soon discharge to the point where the LED will go red or shut off completely.

Audio Input Jack

The XLR input jack on the transmitter accommodates hand-held, shotgun and measurement microphones. Phantom power can be set at various levels for use with a wide variety of electret microphones.

Battery Compartment

The battery compartment door is made of machined aluminum and is hinged to the housing to prevent it being damaged or lost.

USB Port

USB Port for firmware updates in the field.

IR Port

IR (infrared) port for fast setup.

Modulation LEDs

The Modulation LEDs provide a visual indication of the input audio signal level from the microphone. These two bicolor LEDs can glow either red or green to indicate modulation levels. Full modulation (0 dB) occurs when the -20 LED first turns red.

Signal Level -20 LED -10 LED

Less 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	Green		●
Greater than +10 dB		● Red	Red	●

Audio Button

The AUDIO button is used to display the audio level setting, low frequency roll-off and phantom power mode. Repeatedly pressing the button will cycle through the available settings, allowing the UP and DOWN arrow buttons to adjust the values.

Freq Button

The FREQ Button displays the selected operating frequency and also toggles the LCD between displaying the actual operating frequency in MHz and a two-digit hexadecimal number. Frequencies can be selected in either 100kHz or 25kHz steps. The appearance of the hexadecimal number is different in the 100kHz step size mode than in the 25kHz step size mode.

NOTE: The FREQ and AUDIO buttons are used together to enter the standby mode and to turn the power on or off.

UP/DOWN Arrows and Panel Lockout

The UP and DOWN arrow buttons are used to select the operating frequency, adjust the audio level, or set the Compatibility Mode.

Pressing both arrows simultaneously enters the lock countdown. Holding the two buttons in until the count-down is completed locks the control panel buttons so they can only be used to display current settings. "Loc" is displayed to indicate the controls are locked when a button is pressed while the panel is locked.

Once locked, the control panel is unlocked by removing the battery or using the remote control "dweedle" tones.

Antenna

An antenna is formed between the housing and the attached microphone, operating much like a dipole. At UHF frequencies the length of the housing is similar to 1/4 wavelength of the operating frequency, so the antenna is surprisingly efficient, which helps extend the operating range and suppress noise and interference.

Battery Installation

The transmitter is powered by two AA batteries.

Note: Standard zinc-carbon batteries marked "heavy-duty" or "long-lasting" are not adequate.

WARNING: Risk of explosion if the battery is replaced by an incorrect type.

Attaching/Removing a Microphone

The spring loaded coupler under the XLR jack maintains a secure fit to the microphone jack with continuous pressure applied by an internal spring.

To attach the microphone, simply align the XLR pins and press the microphone onto the transmitter until the coupler retracts and latches. A click sound will be heard as the connector latches.

To remove the microphone, hold the transmitter body in one hand with the microphone pointing upward. Use your other hand to rotate the coupler until the latch releases and the coupler rises slightly.

Do not pull on the microphone while releasing the locking collar.

NOTE: Do not hold or apply any pressure to the microphone body while trying to remove it, as this may prevent the latch from releasing.

Operating Instructions

Power Up and Boot Sequence

1) Ensure that good batteries are installed in the unit.
2) Simultaneously press and hold the AUDIO and FREQ buttons. Continue holding the buttons until On and the characters 1, 2, 3 have appeared. The boot sequence will then initiate.

As the unit turns on, the Modulation LEDs and PWR LED all glow red, then green, and then they revert to normal operation.

The LCD displays a bootup sequence which consists of five screens:

Category: Example
Company Name: Lectro

If a remote control signal is detected but the function is turned off, the message rc oFF will be displayed briefly on the transmitter's LCD to confirm that a valid signal was received, but that the remote control function is not enabled.

HMa transmitter settings that can be adjusted:

• Audio input level (gain)
- Operating frequency
- Panel Lock/Unlock
• RF power output
- Low frequency roll-off filter
- Power LED on/off

The LectroRM Smart Phone App is used almost exclusively for remote control. See the section entitled Remote 'Control with Dweedle Tones on page 12 for more information.

Power Back On (DOWN Button Menu)

PbAc (Power back on after power loss) sets the unit to either (1) turn back on after power loss or (0) remain off.

LCD Backlight Setting (Down Button Menu)

The LCD backlight can be set to turn off after either 5 minutes or 30 seconds or stay on continuously. Hold the DOWN arrow in while powering up the unit to enter the setup screen. Press the AUDIO button repeatedly to step through the setup items to reach the backlight settings screen. Use the UP or DOWN arrow button to select the desired setting.

Band/Legacy Block 606 Setting (Down Button Menu)

Allows access to either the full B1, B2 or C1 band or only Block 606. When using a a Block 606 receiver such as an SRb/E01-606 or a UCR411a-606, the pilot tones must match for the receiver to recognize the signal from the transsitter. Press and hold the DOWN arrow button then press the AUDIO button to access.

Available only for E01 models.

AUDIO Button Settings

Press the AUDIO button repeatedly to select the setting. Each time the button is released, the screen will switch to the next setting. Press and hold the button when the desired setting appears on the screen, then use the UP and DOWN arrow buttons to adjust the setting.

Adjusting the Input Gain

The control panel Modulation LEDs indicate the modulation level and limiter activity. This

gain adjustment matches the transmitter gain with the microphone's output level, the user's voice level and the position of the microphone. Once set, the transmitter's audio level setting should not be used to control the volume of your sound system or recorder levels. The audio input level can be set with the unit in Stand-by Mode or while powered up in normal operation.

Signal Level -20 LED -10 LED

Less than -20 dB	Off	Off
-20 dB to -10 dB	Green
-10 dB to +0 dB	Green
+0 dB to +10 dB	Red	Gre
Greater than +10 dB	Red

Note: Voice levels vary significantly between different people. If several different people will be using the transmitter and there is not time to make the adjustment for each individual, adjust it for the loudest voice.

1) With the HMa powered off, insert the microphone plug into the XLR Input Jack, aligning the pins and ensuring that the connector locks.
2) Place the transmitter in the Standby Mode, or if the unit is to be powered up and adjusted, mute the main sound system prior to powering up the transmitter.
3) Position the microphone in the location where it will be used in actual operation.
4) Observe the audio level LEDs while speaking or singing into the microphone at the same voice level that will be used during use. While holding the AUDIO button, press the UP or DOWN arrows until the both the -20 and -10 LEDs glow green, with the -20 LED flickering red on louder peaks. This will optimize the signal to noise ratio of the system with full modulation and adequate headroom to prevent overload and audible compression of signal peaks.

Note: Setting the audio level too high reduces the dynamic range of the audio signal. Setting the audio level too low may cause hiss and noise in the audio.

5) 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.

Adjusting the Low Frequency Roll-off

The roll-off frequency can be set to 35, 50, 70, 100, 120 or 150 Hz.

This setting is often made while listening to the audio while selecting the setting.

Selecting the Phantom Power Supply

The transmitter input jack can provide phantom power for the attached microphone if needed, with voltages at 5, 15 or 48. Phantom power will consume a slight amount of battery power, so it can also be turned off.

Selecting the Phantom Power Supply (Audio Screen Menu)

The transmitter input jack can provide phantom power for the attached microphone if needed, with voltages at 5, 15 or 48. Phantom power will consume a slight amount of battery power, so it can also be turned off.

With the transmitter powered on and in the normal or standby mode, press and hold the audio button and observe the LCD. Release the button and press and hold it again. Repeat this process until the display indicates the PH.

Once you get to the PH setting, keep the AUDIO button pressed, then use the UP and DOWN arrow keys to cycle through the available settings (off, 5, 15, 48 volts) until the desired setting is displayed.

When you release the AUDIO button, the setting will be stored to the value you selected.

About the Phantom Power Supply

Three phantom voltages are selectable from the control panel. The voltages are:

• 5 Volts for lavaliere microphones,
• 15 Volts for some professional mics requiring high current and for many common stage mics that will operate over a wide phantom Voltage range of 12 to 48 Volts. With the proper adapter, this position can also be used with T power microphones. See our web site for details on finding or making the proper adapter.
• 48 Volts for microphones that do in fact require a supply greater than 18 Volts. (See following for a discussion of why 42 and not a “true” 48 Volts.)

For longest battery life use the minimum phantom voltage necessary for the microphone. Many stage microphones regulate the 48 Volts down to 10 Volts internally anyway, so you might as well use the 15 Volt setting and save some battery power. If you are not using a microphone for the input device, or are using a microphone that does not require phantom power, turn the phantom power off.

Phantom power should only be used with a fully floating, balanced device such as most microphones with a 3-pin XLR connector. If you use the phantom power with an unbalanced device or if pins 2 or 3 are DC connected to ground, then you will draw maximum current from the power supply. The HM is fully protected against such shorts but the batteries will be drained at twice the normal rate.

The transmitter can supply 4 mA at 42 Volts, 8 mA at 15 Volts, and 8 mA at 5 Volts. The 42 Volts setting actually supplies the same voltage to a 48 Volt microphone as the DIN standard arrangement due to a dynamic biasing scheme that does not have as much voltage drop as the DIN standard. The 48 Volt DIN standard arrangement protects against shorts and high fault current with high resistance in the power supply feeds to pins 2 and 3. This provides protection if the supply current is accidentally shorted to ground and also keeps the microphone from being attenuated by the power supply.

The HMa improves on those functions and is able to use less power from the battery by using constant current sources and current limiters. With this dynamic arrangement the HMa can also supply more than twice the current of competing 48 Volt plug on units and provide four times the current for some very high end 15 Volt microphones.

FREQ Button Settings

Press the FREQ button on the Control Panel to enter this setup screen. The display will vary depending upon which StepSize setting is selected. See Selecting Step Size on page 9.

Note: The default display is in MHz. Pressing the FREQ button again displays the operating frequency as a two-digit hexadecimal number that corresponds to legacy Lectrosonics products that used two 16-position switches to set the frequency.

While holding the FREQ button, use the UP or DOWN arrow buttons to change the frequency.

Note: The operating frequency displayed on the LCD wraps as it reaches the upper or lower end of its range.

Block 470/19 Frequency Overlap

Frequencies 486.400 - 495.600 Overlap in Blocks 470 and 19

Block 470 and block 19 overlap each other in the frequency range from 486.400 to 495.600 MHz. Since block 470 starts at a lower frequency than block 19, the hex codes (and pilot tones) will not match even though the frequencies are the same in the overlap zone. When using a transmitter on the A1 band with a block 19 receiver, be sure the transmitter is set to block 19 and check the hex code on the receiver to make sure it matches the transmitter.

Call the factory for further questions on this issue.

Set Up in 100kHz Step Size

Frequency displayed in MHz

Frequency displayed as two-digit hexadecimal number

The operating frequency can be displayed either in MHz or as a two-digit hexadecimal number. The example of the two-digit display shown here indicates CH (channel) and 2C as the frequency.

The frequency can be set with the unit in standby mode or when powered up for normal operation.

Set Up in 25kHz Step Size

Frequency expressed in MHz

The hexadecimal display in the 25 kHz mode will appear with a decimal suffix to indicate the 25 kHz steps.

Examples:

Lock/Unlock Screen

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 keypad controls are locked.

The LCD will display the locked condition as long as the arrow buttons are held, then revert back to the previous screen when either button is released.

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.

NOTE: The control panel can be unlocked by removing the batteries or using the "dweedle" tone remote control.

Remote Control with "Dweedle Tones"

Various settings on the transmitter can be adjusted with special audio tones (“dweedle tones”) delivered to the microphone. The tones are generated by a smart phone using the LectroRM app.

LectroRM is a third party application written by New Endian for iOS and Android smart phones that generates the control tones for the remote control functions. The app is available for purchase from the App Store or Google Play for about \$20.

HMa transmitter settings that can be adjusted:

• Audio input level (gain)
- Operating frequency
- Panel Lock/Unlock
- RF power output
- Low frequency roll-off filter
- Power LED on/off

Enable the remote control function by holding the DOWN arrow then pressing the AUDIO and FREQ buttons at the same time. Use the arrow buttons to select on to enable the function, or oFF to disable the function.

If a remote control signal is detected but the function is turned off, the message rc oFF will be displayed briefly on the transmitter's LCD to confirm that a valid signal was received, but that the control function is not enabled. If a remote control setting is delivered to the transmitter that is not available, such as SLEEP/UN-SLEEP in the HMa, the display on the transmitter will show - - - - - and then return to the previous screen.

The usable distance between the microphone and the smart phone will vary with the input gain setting on the transmitter and the volume control setting on the Smartphone.

NOTE: Any microphone/transmitter within range of the Smartphone will "hear" and execute the remote control command. Be careful to make sure only the desired microphone/transmitter is within range when delivering the audio tone.

LectroRM

By New Endian LLC

LectroRM is a mobile application for iOS and Android operating systems. Its purpose is to remotely control Lectrosonics Transmitters, including:

• SM Series
  • WM
  • L Series
• HMa, HMa/E01

The app remotely changes settings on the transmitter 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 \$25 on the Apple App Store and Google Play Store.

LectroRM's remote control mechanism is the use of an audio sequence of tones (dweedles) that are interpreted by the transmitter as a configuration change. The settings available in LectroRM are:

• Audio Level
• Frequency
• Sleep Mode
• Lock Mode

User Interface

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

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 version's default orientation is upside-down but can be configured to orient right-side up. The purpose for this is to orient the device's speaker, which 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 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 however be in sleep mode.
• 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 transmitter must be configured to enable remote control activation.

Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com.

SYMPTOM POSSIBLE CAUSE

TRANSMITTER PWR LED OFF 1) Batteries are inserted backwards or dead.

2) Transmitter not powered up. (See Operating Instructions, Power UP and Boot Sequence.)

AUDIO LEVEL LEDs NOT LIGHTING 1) Gain control set to minimum.

2) Batteries are inserted backwards or dead. Check PWR LED.
3) Mic capsule is damaged or malfunctioning.
4) Mic connector is damaged or mis-wired.

RECEIVER RF INDICATOR OFF 1) Transmitter not turned on, or is in Standby Mode.

2) Transmitter batteries are dead.
3) Receiver antenna missing or improperly positioned.
4) Transmitter and receiver not on same frequency. Check switches/display on transmitter and receiver.
5) Transmitter and receiver not on same frequency band.
6) Operating range is too great.

NO SOUND (OR LOW SOUND LEVEL), RECEIVER INDICATES PROPER AUDIO MODULATION

1) Receiver output level set too low.
2) Receiver output disconnected, or cable defective or mis-wired.
3) Sound system or recorder input is turned down.

DISTORTED SOUND 1) Transmitter gain (audio level) is far too high. Check audio level LEDs and receiver audio levels during use.

2) Receiver output 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. (Use the receiver's Tone function to check level.)

3) Excessive wind noise or breath "pops." Reposition microphone and/or use a larger windscreen.
4) Transmitter is not set to same frequency as receiver. Check that

operating frequency on receiver and transmitter match.

5) Receiver/Transmitter Compatibility Mode mismatched.

EXCESSIVE FEEDBACK 1) Transmitter gain (audio level) too high. Check gain adjustment and/or reduce receiver output level.

2) Talent standing too close to speaker system.
3) Mic is too far from user's mouth.

SYMPTOM POSSIBLE CAUSE

HISS AND NOISE -- AUDIBLE DROPOUTS 1) Transmitter gain (audio level) far too low.

2) Receiver antenna missing or obstructed.
3) Operating range too great.
4) Signal interference. Turn off transmitter. If receiver's signal strength indicator does not drop to nearly zero, this indicates an interfering signal may be the problem.
Use a clear operating frequency.

"Loc" APPEARS IN DISPLAY WHEN ANY BUTTON IS PRESSED

1) Control Panel is locked. (See Operating Instructions, Locking

and Unlocking the Control Panel.)

"Hold" APPEARS IN DISPLAY WHEN ARROW BUTTONS ARE PRESSED

Reminder that it is necessary to hold down the AUDIO or FREQ button to make adjustments to the audio gain or frequency settings.

"PLL" APPEARS IN DISPLAY

Indication that the PLL is not locked. This is a serious condition

that requires factory repair. It may be possible to operate on another frequency far removed from the one that was selected when the unlocked condition was indicated.

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.
