To simplify backward compatibility with earlier Digital Hybrid Wireless® equipment, block numbers are presented along with frequencies in LCD screens.
About Frequency Blocks
A 25.6 MHz band of frequencies, referred to as a Block, came about with the design of the first frequency tunable Lectrosonics wireless products. These products provided two 16-position rotary switches to select frequencies as shown in the illustration below. A logical method of identifying the switch positions was using 16 character hexadecimal numbering. This naming and numbering convention is still used today.
The 16 switch positions are numbered 0 (zero) through F, presented in a two- character designation such as B8, 5C, AD, 74, etc. The first character indicates the position of the left hand switch and the second character indicates the position of the right hand switch. This designator is commonly called a “hex code.”

About Digital Hybrid Wireless®
US Patent 7,225,135
All wireless links suffer from channel noise to some degree, and all wireless microphone systems seek to minimize the impact of that noise on the desired signal. Conventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sending the audio information in digital form, however, it is often at the cost of one or more issues regarding power, bandwidth, operating range and resistance to interference.
The Lectrosonics Digital Hybrid Wireless system overcomes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique which can be accomplished only in the digital domain.
Since the RF link between transmitter and receiver is FM, channel noise will increase gradually with increased operating range and weakened signal conditions; however, the Digital Hybrid Wireless system handles this situation elegantly with barely 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.

FREQUENCY 1.6MHz 100kHz

On older transmitter models, the left hand switch makes steps in 1.6 MHz increments, the right hand switch in 100 kHz increments.
Each block spans a 25.6 MHz band. A simple formula is used to name the blocks according to the lowest frequency in each one. For example, the block starting at 512 MHz is named Block 20, since 25.6 X 20 = 512.

Power Button

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.

LCD Screen
The LCD is a numeric-type Liquid Crystal Display with screens for adjusting output power, frequency, audio level, low frequency audio roll-off and various modes and options. The transmitter can be powered up with or without the RF output turned on. A brief press on the power button turns the unit on in a Standby Mode with the output turned off to allow adjustments to be made without interfering with other wireless systems in the vicinity.

WARNING: Moisture, including talent’s sweat, will damage the transmitter. Wrap the SSM in a plastic baggie or other protection to avoid damage.

BATT LED
This LED glows green when the battery is good. The color changes to red when there is only a few minutes of operation left. The LED will blink briefly, just before the unit powers down. The exact point at which the LED turns red will vary with battery brand and condition, temperature and current drain. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time.
AUDIO Button
The AUDIO button is used to adjust the audio output level and low frequency roll-off. Each press of the button will toggle between the two settings.
FREQ Button
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 Lectrosonics Frequency Switch Setting.
Power Button
Turns the unit on and off. A brief press turns power on in a Standby Mode to make settings without interfering with other wireless systems in the vicinity. Pressing and holding the button until a counter on the LCD completes a sequence turns the power on with the RF output turned on. Pressing and holding for the duration of a countdown turns the unit off.
UP and 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.
Turning LEDs ON and OFF
These arrow keys also turn the LEDs on and off. With no other button pressed, the UP arrow turns the LEDs on and the DOWN arrow turns them off. When the LEDs turn red, the LCD will display a reminder every few seconds.

Operating Instructions
Powering On in Operating Mode
Press and hold the Power Button for several seconds until a counter on the LCD progresses from 1 through 3, followed by a display of the model, firmware version, frequency block and compatibility mode.

Screens Used in Normal Operation
When the transmitter is turned on with the RF output on, the LCD will display the frequency, audio gain or LF rolloff point.
Audio gain is expressed in dB.

When you release the button, the unit will be operational with the RF output turned on and the Main Window displayed.
Powering On in Standby Mode
A brief press of the Power Button , releasing it before the counter has reached 3, will turn the unit on with the RF output turned off. The LCD will display a reminder that the RF output of the transmitter is turned off.

Frequency is displayed in one of two ways:
Frequency expressed in MHz

Standard frequency block (22)

Frequency in hex
code (C8)

Offset in MHz (.75)

LF roll-off is expressed in Hz.

In this Standby Mode the frequency can be browsed to make adjustments without the risk of interfering with other wireless systems nearby.
After adjustments are made, press the power button again to turn the unit off.
Powering Off
Holding the Power Button in and waiting for the completion of the countdown from 3 to 1 will turn the power off.

To make changes to the settings, press either button to display the desired screen, then use the UP and DOWN arrows to select the value. The changes take effect immediately when you release the buttons.
Block 470/19 Frequency Overlap

If the power button is released before the countdown is completed, the unit will remain turned on and the LCD will return to the same screen or menu that was displayed previously.
Setup Screens
Two different setup menus are accessed by holding either the UP or DOWN arrow button while powering the unit on. See the following page (Setup Screens) for a listing of the menu items and descriptions.

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 if you have questions about this issue

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

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

1. With a charged battery in the transmitter, power the unit on in the standby mode (see previous section Powering On in Standby Mode).

2. Press and hold the AUDIO button with Aud and a numeral on the display (e.g. Aud 22).

3. 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 occur during use, or set the output level of the instrument 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. Unless the microphone or its position changes, or a different instrument is being used, leave the transmitter gain adjustment set according to these instructions. Use the audio output level control on the receiver to make adjustments for the desired level being delivered to the connected mixer, recorder, etc.

IR (infrared) Sync
An IR (infrared) link between an associated receiver and the transmitter can be used to shorten setup time and ensure that the correct settings in the transmitter are made. The dome on the side panel of the transmitter is the port used for the IR link. The receiver is normally used to identify a clear operating frequency. Once step size, frequency and compatibility mode are set in the receiver, the settings can be sent to the transmitter via this IR link.

When mounting the belt clip onto the battery door, carefully align the openings with the retaining tabs on the door. If they are not precisely aligned, the door may not close and latch properly.
Align the openings and tabs precisely.

IR port
Place the transmitter close to the IR enabled receiver with the ports facing each other within a foot or two apart. Send the settings with the trigger on the receiver. If the settings are successfully transferred, a confirmation message will appear on the transmitter LCD.

Remote Control
Remote control signals (“dweedle tones”) may be used to control the transmitter. The tones are played back into the microphone to avoid the need to reach and handle the transmitter when making changes to the following adjustments and settings:
· Input Gain
· Sleep/Unsleep
· Lock/Unlock
· Tx power output
· Frequency
A Smartphone app is available in the App Store and in Google Play to implement this control. Search for the title LectroRM.

NOTE: If a mismatch exists between the receiver and transmitter, an error message will appear on the transmitter LCD stating what the problem is.

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

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

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.
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 e-mail 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 or FEDEX 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.
